On March 18, 2021, an extreme rainfall event kicked off, resulting in severe flooding in the Mid North Coast of New South Wales. 18,000 people were evacuated, including 1,000 flood rescues. Flooding also impacted the North Coast, Hunter, Western Sydney, South Coast, Central West, and North West Regions of NSW. Flooding was also experienced in Southeast Queensland. The focus of this briefing is on flood impacts experienced on the NSW Mid North Coast.

Overview

On March 24, Risk Frontiers, with assistance from the BNHCRC, deployed a survey team to the NSW Mid North Coast region to observe and report on significant flooding in the area. Areas surveyed included, Bulahdelah, Taree, Wingham, Port Macquarie, North Haven, Laurieton, and Dunbogan. In addition to measuring flood depths and recording noteworthy damages to belongings and infrastructure, the team spoke with residents, business owners, and rescue personnel (Rural Fire Service, NSW Fire and Rescue, and State Emergency Services). Discussions covered evacuation, emergency response and communication, community resilience, and the insurability of their homes.

A couple of key issues emerged during the investigation. The first was insurance affordability in areas that were clearly at risk of flooding. Some residents and business owners we spoke with cited quotes for policies covering flood ranging from $5k - $30k per year. Our survey indicates that the full extent of damage will not be evident in claims data due to the low rates of insurance as a lot of individuals had chosen to remain uninsured due to the prohibitive costs quoted for them. Disaster mitigation needs to be considered in these areas to assist with insurance affordability.

Another common concern expressed was the lack of warning and mitigative action. For example, some residents had not considered sandbagging. Residents claimed they were either misinformed or warned too late, and then felt aspects of the process to recover were unclear.

Flooding impacted large areas of Townsville from Wednesday 30th January 2019, as a consequence of heavy rainfall across the north of Queensland. The Bureau of Meteorology (BoM) noted that 370mm of rain fell within 24 hours at Paluma near Townsville. Almost 3300 properties were damaged, thousands were asked to evacuate and there were widespread blackouts . The flooding came in waves, with the initial rainfall causing around 30 cm of flooding in the worst affected areas. This subsided somewhat before more rain fell in the catchment, necessitating the release of water from the Ross River Dam, which led to flood depths of up to 1.6 m over floor height.

Risk Frontiers and Insurance Council of Australia staff visited Townsville on 11th and 12th February, supported by a grant from the Bushfire and Natural Hazards CRC. The aim was to undertake unstructured interviews with residents and business operators to gain preliminary insights into impacts and responses to warnings and to examine initial recovery. In total, more than 20 residents and six business operators were spoken to. This briefing note highlights key preliminary themes that arose from this research.
