Protect your Deck from Wildfire (Bushfire)

Decks are used for many family and social activities. A deck that is attached to a home can threaten the home if ignited by the wildfire. Once ignited, a burning deck can threaten your home by breaking glass in window or sliding glass doors, igniting your siding and burning into house, and by flames spreading vertically and laterally up the siding into the area under the eave and entering the attic. Minimizing the chance that a deck will ignite, and if it should it ignite, minimizing the chance that fire can spread to your home is an important part of hardening your home against wildfire. In this video how your deck can be ignited during a wildfire will be reviewed, as will actions you can take to make your new or existing deck less vulnerable.

Jan 21, 2008, The National Wildland/Urban Interface Fire Protection Program www.firewise.org Using Water Effectively in the Wildland/Urban Interface FWC-625-04-V This training video for fire departments shows various approaches to using water wisely for reducing interface structure loss. Using Water Effectively in the Wildland/Urban Interface can help change the way fire departments address the risk to interface residences and structures, through Firewise preparation and mitigation before a wildfire threatens a community. The video is incredibly valuable and informative to show different ways of using water effectively in interface firefighting and provides examples of techniques or strategies including planning and locating water sources, accessing those water sources for supply; and testing and maintaining the source. Some of the tactics shown include: developing quick engine fill sites, making the best use of limited water, proper use of foams and gels, mobile water delivery using various extinguishing options, and site preparation to reduce water needs.

 

NOTE: This is an old video (2008) that was made as a training video for firefighters and therefore offers an interesting and different perspective and valuable clues that residents can utilise.

The computer program that saved a town: A fire ecologist and a programmer have teamed up to develop a tool that is changing the way we fight bushfires – for the better.

January 2, 2015: An ominously hot Friday at the height of a bone-dry Australian summer. Bill Taylor remembers the wind, a “stiff northerly”, as one harbinger of the trouble ahead. Just before noon, Mr Taylor, farmer and fire captain of Moyston, in Victoria’s western district, received a pager message that a fast-moving grass fire was bearing down on the town and its 350 residents. “By the time I got there it had progressed about 400m and was 50m wide,” he recalls. “It jumped the road and we’d lost it. “It got into a paddock of old Phalaris (grass). Two of our trucks were on site, but the flames were rearing above where the firefighters were standing. They had to back off due to the radiant heat.” Access full article here

 

Fire, Space and Time

Kevin Tolhurst has spent thirty years studying the role, impact and management of fire in the Victorian environment. In the Wombat Forest, 100 kms north-west of Melbourne, he reflects on the need to appreciate fire as a defining force and presence and to develop a stronger knowledge of the environments in which we live.

ABC February 2019: Kevin’s Story | Aftermath: Beyond Black Saturday

Dr Kevin Tolhurst, Associate Professor of Fire Ecology and Management at the University of Melbourne.Kevin Tolhurst is a bushfire behaviour scientist who provided the risk assessment for Brown Hill residents northside. This short video lets you hear from him directly. He talks about where he was on Black Saturday — called in from a day off at six in the morning, spending the day at the State Control Centre watching a disaster unfold that none of them had seen anything like before. He describes that sinking feeling of not quite believing how bad it was getting.

He then explains Phoenix, the fire simulation model he was central to developing — how it draws on real weather forecasts, terrain, fuel loads, and fire history to predict where a fire is likely to go before it’s even started. It’s a plain-language explanation that makes sense without a technical background.

He closes with something worth sitting with: that there’s no way to remove bushfire from the Australian landscape, and that what we actually need to do is learn to live in a fire environment “working with the environment much more, rather than trying to control it.” That’s the foundation the FireAware Network is built on.

Since Black Saturday, Phoenix Rapid Fire, a fire simulation program designed by for ecologist, Associate Professor, Kevin Tolhurst has been widely adopted throughout Australia by Land Management and Fire Agencies for fire behaviour, prediction, research and risk analysis.
7 June 2009:The Black Saturday fires were a “blow-up” – a ferocious mix of factors only now being understood, writes Michael Bachelard. (Sydney Morning Herald) KEVIN Tolhurst is not prone to emotive outbursts. A scientist who has spent his career analysing bushfire behaviour, he has presented the most astounding evidence in the most dispassionate manner to the Bushfires Royal Commission. But on the afternoon of February 7, when he saw the predictive map of the Kilmore East fire that one of his trainees had produced, he admits he was “horrified”. The map showed Victoria’s most deadly fire front heading swiftly into the suburbs of Melbourne — Eltham, Greensborough, St Helena, Warrandyte; heavily populated, leafy places, well within range of flame and flying ember.

If the prediction had come to pass, parks and gardens would have been alight and houses incinerated, Tolhurst says. Power to the area would probably have failed and power poles collapsed; cars would have been unable to get out, fire trucks unable to get in. The fire would have raced up wooden fence lines, using them as wicks, setting gardens alight. Burning houses would ignite properties next door, causing a “mosaic” of fires for two days, causing confusion, panic and possibly death. “Just the number of people that were likely to be impacted by the fire … you get wall-to-wall traffic and everything jammed up … it’s a paralysis effect,” Tolhurst told The Sunday Age. That none of this happened was due to luck and meteorology. The prediction was based on a weather forecast of a cool wind change coming through at 9pm. As it happens, it came through earlier, at 6pm, and blew the fire towards Kinglake, where 38 people died.

 

Phoenix Rapid Fire

What is Phoenix? Phoenix Rapid Fire (Phoenix) is a research tool developed by the University of Melbourne (Kevin Tolhurst and Derek Chong). It has been used by fire agencies for both incident prediction (State Control Centre) and as a key tool for bushfire risk assessment and strategic bushfire management planning. For more information

Understanding bushfire risk, warnings and responses – lessons from the 2018 Reedy Swamp fire

6 March 2020 Bushfire & Natural Hazards CRC Report: On Sunday 18 March 2018 a bushfire impacted on the communities of Reedy Swamp and Tathra in the Bega Valley Shire on the NSW south coast. The fire, known as the Reedy Swamp Fire, destroyed 65 and damaged 48 homes. 35 caravans and cabins were also destroyed. The fire displaced approximately 700 residents on the day, as well as an unknown number of tourists and visitors to Tathra. Fortunately no human lives were lost. The NSW Rural Fire Service (NSW RFS) commissioned the Bushfire and Natural Hazards Cooperative Research Centre to undertake research into community preparedness and responses to the Reedy Swamp fire. The research involved 87 semi-structured, in-depth interviews with 120 people affected by the fire.

Ten years after the Black Saturday fires, what have we learnt from post-fire research?

April 2019 edition– Australian Journal of Emergency Management

Researchers were deployed within days of the Black Saturday bushfires in 2009, assessing community behaviour, fire behaviour and building construction.Ten years ago, 173 people lost their lives and more than 2000 homes were destroyed in the Black Saturday bushfires. The fires of 7 February 2009 led to a royal commission and significant changes to bushfire management throughout Australia. Research played an important role in the royal commission and subsequent changes. This paper reflects on what was learnt from research into human behaviour and community safety undertaken as part of the Bushfire CRC 2009 Victorian Bushfires Research Taskforce. The research involved interviews with over 600 householders and a mail survey of 1314 households affected by the fires. This paper reviews findings from subsequent post-fire research to consider the extent to which there have been changes in findings related to community planning, preparedness and responses to bushfire. The review suggests that many of the issues encountered on Black Saturday—limited awareness of and preparedness for bushfire risk, a tendency for leaving (or evacuating) at the last moment and a commitment to defending, even under the highest levels of fire danger—persist, despite major changes to policy and public messaging.

Learning to learn from bushfires

November 2015, Graham Dwyer, Doctoral Researcher, Faculty of Business and Economics, University of Melbourne

Finger pointing, blame and scapegoating is not the answer. Looking forward and understanding the risks is the right way. In October, a large bushfire created headlines in Australia proclaiming that fire seasons are starting earlier and earlier. The experts have been telling us this for a decade. Professor Tim Flannery has said: Worryingly, since 2009 we have experienced more days of catastrophic fire danger, and this number will very likely increase in the future.” What are we doing to prepare for this scenario?

In the last 10 years, one of the ways emergency services, governments and the public learn from bushfires has been through public inquiries such as Royal Commissions. Emergency services also seek to learn continuously through independently commissioned reviews and operational debriefs. However, governments will likely establish a Royal Commission after a major bushfire. Unfortunately, the last bushfire Royal Commission — after the 2009 Black Saturday fires — resulted in finger pointing, blame, vilification and scapegoating. We have already seen these characteristics at the start of this year’s fire season, which only keeps us looking backwards when we need to look forward.We now know enough about bushfire behaviour and how our community and emergency services react that the money, time, energy and political attention devoted to Royal Commissions would be better spent planning for the future. This is a key finding from my three years of doctoral research, including interviews with 63 Victorian emergency services experts, and an analysis of public inquiry reports, recommendations and comments from politicians and experts since 1939 — Victoria’s first bushfire Royal Commission.

Reports

CSIRO report released Wye River and Separation Creek bushfires

10 May  2016 A CSIRO report released into the Wye River and Separation Creek bushfires identifies ignition of extensive surface litter and domestic fuels within the township as the main contributors leading to house loss. The review, commissioned by the CFA, identifies the factors that led to the loss of and damage to more than 100 houses and the survival of others following the bushfires on Christmas Day. CSIRO experts conducted surveys of houses within the fire footprint from January 6-8 as part of the study which highlights a range of weaknesses in building design and materials, vegetation management and the storage of heavy fuels as the main factors impacting house loss.

 

Other key factors identified in the report as contributing to house loss include:

  • No distinct border between the forest and urban areas of the township with widespread established tree coverage spread across residential properties
  • Extensive surface litter provided a near continuous flammable fuel bed
  • Ignition of heavy fuels such as plastic water tanks, building materials, small garden sheds, boats and kayaks stored under or adjacent to houses
  • Strong evidence of house-to-house fire spread despite the generally large distances between buildings of up to 12m
  • Timber retaining walls provided a direct threat to buildings and adjacent fuel elements
  • Positioning and storage of LPG pressure vessels

Indicators of Fire Vulnerability:   Risk Factors in Victorian Settlements  Kimberley; Alan March; Justin Leonard; Glenn Newnham

March 2014, Recent research shows that as metropolitan and major regional area areas grow quickly in Australia, proportionally greater amounts of land are being developed as fragmented, low density peri‐urban settlements (Low Choy, Sutherland, Gleeson, & Sipe, 2008).  This development form will expose increasing numbers of houses to bushfire threats (Buxton, Haynes, Mercer, & Butt, 2011).  Ensuring that new settlements can deal with bushfire threats is a central element of ensuring Australian settlements’ long‐ term resilience, particularly as the incidence and intensity of extreme weather increases (Lucas, Hennessy, Mills, & Bathols, 2007).   Access full report here

Bushfire risk at the rural/urban interface 

Blanchi R.M., Leonard J.E., Leicester R.H. CSIRO CMIT, Highett, Victoria ; Bushfire CRC

Abstract: Living in a bushfire prone area provides many lifestyle advantages but also presents a risk to life and property. This paper describes the development of a model to predict the potential risk of loss of a specific house at the rural/urban interface.

The three fundamental mechanisms of attack have been considered: embers, radiation and flame contact. The spatial and temporal properties of these attack mechanisms are combined with our evidence based knowledge of house loss. The probabilistic model takes into account a wide range of parameters such as vegetation, climatic conditions, topography, building design, human behaviour and other infrastructure elements close to the house. Each of these elements may play a role in mitigating or contributing to the risk of building loss.

The model uses the principle of aggregated probability of failure of each object that contributes to the risk of house loss. The outcomes of the model provides a risk estimation for any given building/environment/people scenario and allow us to determine the level of risk mitigation achieved by a specific strategy or combination of strategy. The application of this model will be tailored to fellow researchers, community education, policy developers, town planning, and regulation reform. Access full paper here

Human Settlement Fire Vulnerability

March 2014, Melbourne School of Design (Melb Uni): Climate Change Adaptation: Suitability Indices of Human Settlement Fire Vulnerability. In the context of increasing fire risks resulting from climate change, metropolitan and many regional area in Australia are growing quickly. This growth is exposing increasing numbers of houses to bushfire threats. There is a need for improved bushfire assessment tools at the strategic planning level for existing and proposed human settlements to ensure that new housing is appropriately located and designed, and that existing settlements facing high fire risks can be improved. Current design guides tend to focus on individual buildings, giving little comprehensive attention to the arrangements of settlements overall, a form of maladaptation which may actually encourage increased amounts of settlement in areas of high bushfire incidence. This project developed an index of fire vulnerability to assess existing and projected settlement areas, extant policy, and to guide improved adaptation to climate change.Access full report here

Learning from 100 years of bushfire loss data

20 December 2016, ECOS, CSIRO, …….Current building regulations are only designed to be effective only up to ‘extreme’ conditions, so, as Leonard puts it: “All bets are off, even for a regulated house when you get to catastrophic.” “In a sense, we’re resigning ourselves to the inevitability that when we have those days we’re going to lose thousands of houses and hopefully only a handful of people.” Future-proofing our homes, now This scenario may become even less palatable as the changing climate brings an increase in the likelihood of catastrophic weather conditions. For many parts of Victoria, catastrophic weather conditions are roughly 1-in-20-year conditions, meaning that in any one bushfire season there is about a 5 per cent likelihood that such catastrophic bushfire conditions will arise. By 2050, that likelihood could increases to about 15 per cent, says Leonard, and by 2100 about 30 per cent. “The inevitability that a big fire will run on that day is nearly absolute – it just depends where in the landscape it’s going to turn up,” he says.

December 2012, CSIRO Report: Life and house loss database description and analysis Final report. This report describes the development and analysis of a dataset containing bushfire related life loss in Australia over the past 110 years (1901-2011). Over this time period 260 bushfires have been associated with a total of 825 known civilian and firefighter fatalities. This dataset encompasses the spatial, temporal and localised context in which the fatalities have occurred (known as the Attorney General Department’s (AGD) NFDRS Life Loss database). This database was developed to provide a firm evidence base for which an Australian National fire danger rating system can be developed. It represents the most complete set of known bushfire fatalities and the most comprehensive spatially and temporally correlated dataset of these fatalities ever assembled. The analysis phase of the project has focused on the characterisation of the relationship between fatal exposure location, fire arrival, weather conditions (using the McArthur Forest Fire Danger Index (FFDI) and its individual components), proximity to fuel, and fatality activity and decision making leading up to the death.

NCCARF: Bushfires are extremely unpredictable climate-related events. They already pose a significant threat to life and property. Adapting to an increased risk will mean improving existing preparedness and response activities. Weather conditions that lead to bushfires are expected to worsen with climate change. Even under current conditions, complex and large bushfires can have catastrophic outcomes. Five principal adaptation challenges emerge from the research evidence: Read More here

 

Issues in Community Bushfire Safety

December 2011: Report Number 4: 2011 Issues in Community Bushfire Safety: Analyses of Interviews Conducted by the 2009 Victorian Bushfires Research Task ForceSchool of Psychological Science La Trobe University. Access full report here

EXTRACT: Section 6 Concluding Discussion Bushfire Survival Plans

Bushfire Survival Plans: It was clear from the content of the transcripts that householders’ understandings of what constitutes a meaningful bushfire survival plan differed greatly. Many residents of isolated rural properties who intended to stay and defend had quite sound plans and had prepared accordingly. Many residents who lived in town streets and planned to stay and defend failed to take into account possible loss of electric power and town water supply. The overwhelming majority of bushland urban interface (‘suburban’) residents had never seriously considered the possibility of bushfire threat: they were, effectively, ‘blind’ to the implications of adjacent bushland and thus had no bushfire survival plan.

It seems from the transcripts that in the absence of a major change in community perceptions of bushfire risk, very few residents in at-risk areas are likely to leave and go somewhere safer the day before a predicted day of total fire ban. Based on the transcripts of the few who did so in light of the fire danger weather warnings prior to 7 February 2009, those most likely to do this are people who are elderly or have young children and have a second residence elsewhere, such as a major city.

It was also clear from the content of the interview transcripts that there was a general failure by residents to understand the necessary requirements of a sound plan to leave safely under the stress of potential bushfire threat. Indeed, for most survivors who did not attempt to defend, their ‘plan’ seemed to consist of an intention to simply not be there if a fire threatened. Prior household consideration and discussion of suitable places to go, alternative routes to travel, what would constitute the trigger for safe departure, and what preparations were needed to make leaving safe and minimally inconvenient mostly had not happened. In many households, the needs of pets and livestock, young children, and elderly/handicapped members of a household had not been thought about.

Preparing, Staying and Defending: The overall impression created by the transcripts of ‘stay and defenders’ was that most had planned and prepared for a low to moderate intensity bushfire which could be dealt with quickly and easily without undue risk. We speculate that such an anticipatory understanding was created, at least in part, by a decade of television news images of residents wearing shorts, singlets and thongs, easily subduing flames of about half a metre in height using a plastic garden hose. There appeared to have been a general failure to appreciate the potential threat posed by a high intensity bushfire on a day of extreme fire danger weather, and ways in which houses are vulnerable to sustained ember attack associated with very strong winds.

In general, household bushfire ‘human-machine defence systems’ were brittle, and most failed to a greater or a lesser extent in face of high-intensity bushfire attacks lasting 30 minutes to more than an hour. Mains electrical power and water supplies failed. Plastic pipes and fittings melted due to radiant heat, petrol driven pumps motors stopped as fuel vaporised in carburettors, plastic water tanks melted, defenders got injured and/or became incapacitated through fatigue. Defenders were distracted from their primary survival-focussed tasks by concerns about the safety of less-able household members.

A robust fall-back plan to survive if defence failed and the house burned was rare. There seemed to be a generally low level of prior appreciation of the lethally destructive effects of radiant heat from a bushfire.

Notwithstanding, there were some accounts of successful household defence that demonstrated survival-enhancing behaviour under adversity. Most of these accounts described an acknowledgment of the high level of threat, extensive long and short-term preparation (including back-up plans if defence failed). The interviewees also reported high levels of personal and outcome efficacy (i.e. they were confident in their own abilities and their preparations), they remained task-focused and identified emerging threats, and were able to set aside potentially distracting thoughts or negative emotions like fear/anxiety. These interviewees were mostly rural land owners and those with some prior bushfire, or closely related (e.g. military), knowledge and/or experience.

Leaving Safely: As suggested above, an overall impression created by the transcripts of ‘leavers’ was that few had thought beyond a simplistic notion of ‘if a bushfire threatens we are out of here’. Another overall impression is that the typical ‘plan-in-action’ of those who ultimately left involved ‘waiting and seeing’, without having any clear idea of what they were waiting for and what they might expect to see that would spur them into action. A prior plan which comprised a checklist of preparations for leaving; agreed alternative safe havens and travel routes; and an agreed trigger set of circumstances which would initiate leaving, was rare.

While there were few fatalities on the day associated with leaving late in vehicles (n = 7, 4% of fatalities: Handmer, O’Neil, & Killalea, 2010, p. 24), some survivors’ accounts of their journeys leave a disturbing picture of ‘what might have been’ if even a single large tree had fallen and blocked any one of several major escape roads used by residents fleeing at the last minute.

Several of those interviewed indicated a belief, presumably based on bushfire safety messages, that it was dangerous to be on the roads in a bushfire. For some, paradoxically, this belief appeared to be a factor in delaying departure and potentially increasing their actual risk when evacuation became unavoidable. While there were fatalities associated with vehicle accidents and entrapments (see above), others survived because they used their vehicles as mobile last-resort ‘fire shelters’ in locations relatively clear of fuel (McLennan, 2010).

Location-Specific Issues Concerning Expectations and Bushfire Survival: While not coded for, two important issues emerged from the transcripts related to two specific locations. Several transcripts of interviews with Marysville survivors expressed the view that there was a widespread belief among residents that ‘Marysville would never burn’, largely because there was no prior history of bushfires ever impacting the town (the town was not impacted by the 1939 Black Friday fires). Several transcripts of interviews with householders in the Kinglake area indicated that many residents believed that any fire which broke out on 7 February 2009 would be a repetition of events associated with the bushfire which occurred in 2006: slow rate of spread, ample warning from authorities, and plenty of time to prepare properties or to leave safely (—and ultimately this fire did not threaten life or property).

Learnings from the 2015 Wye River bushfires

20 December 2016, ECOS CSIRO. What Wye River can teach us about building for bushfiresOn Christmas Day 2015, the weather conditions around southern coastal Victoria weren’t particularly notable. There had been a long dry spell, and a total fire ban had been forecast, but otherwise there was little to forewarn of what was to come. That day, a bushfire swept through the small coastal township of Wye River and destroyed more than 100 houses – 80 per cent of the town. Thanks to early warnings and a fast-acting community, no lives were lost. But the devastating event has revealed some significant flaws in our interpretation and implementation of bushfire regulations, as well as highlighting opportunities for improvement. Some of the houses that burned in the Wye River fire had been built to bushfire regulations. There is a misconception that this makes them bushfire-proof, and this reveals a basic flaw in our understanding of the aims of these regulations. The goal of bushfire building regulations is ultimately to prevent loss of life, by making a house that can withstand bushfire long enough that its occupants can escape safely after the fire front has passed. But no house is an island. It is surrounded by other houses, by landscaping, by add-ons, by natural debris, by the everyday bits and pieces of life, and by an environment whose aesthetic appeals to its owners. None of these elements are covered by bushfire building regulations, and each one of these can significantly amplify the impact of a bushfire on a house and a community. Read More here

July 2010, Final Report, preface extract: This report is an important part of securing the memory of the fires. The first volume describes the origins and course of the 15 fires that wrought the greatest harm on 7 February and the response to them. It also tells the stories of the 173 people who died. Volume II looks at what lessons can be learnt from these experiences—how we can reduce the risk and impacts of fire and minimise fire-related loss of life in future. Volume III reports on the Commission’s administration and processes. Volume IV reproduces the statements of the 100 lay witnesses who gave personal accounts of their experiences in the fires in late January and February and in their aftermath. The stories told by these people grounded our work. They continually reminded all at the Commission that bushfires deeply affect people and communities and that their needs and safety must be at the forefront of government policy….

Victoria has a long, sometimes devastating, history of fire. The conditions on 7 February gave rise to particularly destructive bushfires. These very intense fires share some features that set them apart from less intense fires. Very dry fuels and strong surface winds resulted in erratic fire behaviour and the development of strong convective activity capable of lifting firebrands such as burning bark high in the convection column. Strong upper air winds transported burning bark downwind for many kilometres, resulting in long-distance fire spotting. Spotting was an important factor in the spread of some fires. Firebrands carried by the strong winds spread from one ridge top to the next in areas of broken terrain. They were carried across sparse eaten-out pasture or areas where grass was less than fully cured and might otherwise have arrested the fires’ spread. Although they varied in their size and impacts, the most severe of the 7 February fires the Commission examined shared a number of features:

  • Rapid fire spread followed ignition, which responding crews could not contain.
  • Fires crowned in forested areas, which made them impossible for ground crews to control.
  • Powerful convection columns were generated above the fires.
  • Extensive forward spotting occurred as a result of the fuel type, the weather conditions and the topography.
  • Late in the day a wind change altered the direction of fire spread and extended the firefront

Investigation of bushfire attack mechanisms resulting in house loss in the act bushfire  2003 Bushfire CRC Report

April 2005 Raphaele Blanchi and Justin Leonard

Preliminary studies of the damaged area around Canberra revealed unusually high impact levels of both wind and fire attack, with a significant loss of houses. It appears that most houses were ignited by either ember attack or house-to-house ignition. These ignitions were exacerbated by high localised winds that damaged houses in some parts of Canberra during the fire event, thus making them more vulnerable to ember attack.

The insured losses in the Canberra fires were comparable to the losses on Ash Wednesday with inflation taken into account, even though the number of houses lost was much less. In terms of insured losses, Ash Wednesday stands as Australia’s largest bushfire event and sixth largest natural disaster. If the Ash Wednesday losses are indexed to inflation to today’s prices, it represents a total insured loss of $300–350m (Walker 2002), with 1511 houses lost (Leonard & McArthur 1999).

Canberra’s total insurance loss approaches this level, with approximately 516 houses destroyed. There is a considerable increase in the asset value at the urban interface that needs to be considered during future policy development. Thankfully, life loss has not followed the same trend, with 75 lives lost in the Ash Wednesday fires compared to 4 lives lost in the ACT fires.

However, structural loss so deep into the urban area interface has not been observed since the Hobart fires of 1967 (Leonard & McArthur 1999), which resulted in 62 deaths, and destroyed 1300 homes and 128 major buildings, and was the seventeenth largest insurance loss in Australia’s history (IDRA) (McArthur 1968; Walker 2002).

House Select Committee on the recent Australian bushfires

On 26 March 2003 the House of Representatives established a Select Committee to inquire into the recent Australian bushfires. The Committee invited interested persons and organisations to make submissions addressing the terms of reference and it held public hearings around Australia. The committee tabled the report of its inquiry on Wednesday 5 November 2003. The tabling of the report concluded the committee’s work and the committee was then dissolved.The Australian government presented its response to the report on Thursday 15 September 2005.
