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. RESEARCH SCOPE AND METHODS 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 University of Wollongong and Macquarie University were engaged by the Bushfire and Natural Hazards Cooperative Research Centre to conduct this research. The NSW RFS Statement of Work identified the following themes for investigation: Establishing the community context • Understand the socio-demographic characteristics of the community • Identify and document the history of previous bushfires in the area Community planning (long term) • Assess the community’s perception of bushfire risk prior to the Reedy Swamp Fire • Assess community awareness and attitudes toward bushfire risk reduction activities in the area over recent years such as: Hazard reduction burning; Fire trail management; Bushfire construction measures for dwellings; Mechanical works, such as establishment and maintenance of Asset Protection Zones (APZs); community engagement; and ignition management Community preparation (short term) • Identify what information and sources people used when planning and preparing for bushfire • Identify what action people took to prepare for this fire season, including fire plans and preparedness measures • Establish what the community’s perception of the risk posed by the forecast fire danger rating and conditions leading into the bushfire, and their subsequent response 3 UNDERSTANDING BUSHFIRE RISK, WARNINGS AND RESPONSES: A STUDY OF THE 2018 REEDY SWAMP FIRE | REPORT NO. 518.2020 Community responses to the fire • Establish how the community became aware of the bushfire and how they reacted to it • Identify if people were able to implement their fire plan. Why they did/did not implement their plan • Identify what information people sought about the fire and how they obtained it and what they did with it • Establish how people/ businesses hosting non-residents responded to the fire; • Establish the community’s expectation of warnings and information, particularly in known mobile coverage black spots; • Establish the effectiveness of warnings delivered to the community during the fire event, and the resulting actions taken as a result of these warnings • Identify if the time of year (i.e., later in the bushfire season) influenced how people responded to the fire Community responses after the fire • Identify the experiences of the community in the aftermath of the bushfire, such as communication and information, evacuation centres, returning home etc. • Establish how people intend to plan, prepare and respond to a bushfire in the future. Investigation and analysis of firefighting responses and building impact assessments were outside the scope of this research. The research involved 87 interviews with 120 people affected by the Reedy Swamp Fire. Interviews were audio recorded with each participant’s consent and transcribed in full, generating over 1300 pages of interview transcript. Qualitative analysis of interview data was undertaken using the qualitative data analysis software NVivo 11. This process involved careful reading and rereading of each interview transcript and sorting (coding) information related to the issues and themes under investigation to derive summary findings (Thomas 2006). 4 UNDERSTANDING BUSHFIRE RISK, WARNINGS AND RESPONSES: A STUDY OF THE 2018 REEDY SWAMP FIRE | REPORT NO. 518.2020 KEY FINDINGS 1. Assess the community’s perception of bushfire risk prior to the Reedy Swamp Fire Key insight – Many residents within the town of Tathra were not aware of the bushfire risk. • Residents with properties within or adjoining the forest tended to be more aware of the risk posed by bushfire and were more likely to have taken action to plan and prepare. • Tathra residents often referred to the forest that adjoins the town’s western edge as the prime source of bushfire risk. • Many people within the town had not considered that a bushfire could impact on Tathra, or had not considered the potential for a bushfire to penetrate beyond the forest edge (e.g. via embers). 2. Assess community awareness and attitudes toward bushfire risk reduction activities Key insight – Many people were aware of activities that had been undertaken to reduce bushfire risk, including hazard reduction, Asset Protection Zones (APZs) and RFS community engagement. These activities were viewed
