The data released by NRMA Insurance through its wild weather tracker is based on a seasonal analysis of insurance claims data showing the impact of severe weather in NSW, Queensland and the ACT.

NSW experienced its most devastating autumn in five years with floods and storms triggering more than 14,000 home claims, NRMA Insurance said. This represents 76 per cent of all home claims in NSW in autumn 2021 and is triple the five-year average.

Port Macquarie was ranked the worst-affected region in NSW with North Haven, Dunbogan, Nambucca Heads, Taree, Laurieton and Forster also in the state's top 10.

The data for March 2021-May 2021 show over three-quarters of all home claims in NSW were the result of natural disasters or severe weather, with 21 per cent of all claims from the Mid North Coast region.

On the Mid North Coast, the regions most impacted were Port Macquarie, North Haven, Dunbogan, Nambucca Heads, Taree, Laurieton, Wauchope, Macksville, Harrington and Lake Cathie.

The flood recovery effort across the Mid North Coast continues with families in some of the hardest hit regions including North Haven and Telegraph Point, still displaced after their homes were destroyed.

The tracker also analyses new research from NRMA Insurance on community attitudes to preparedness.

When asked to self-assess their readiness for wild weather on a scale of 1 to 100, residents of the North Coast, Mid-North Coast and Far South Coast felt most prepared, while residents in Sydney's Eastern Suburbs and Inner West felt the least prepared of any region in NSW.

Executive general manager, direct claims Luke Gallagher said the last 18 months have been demanding for so many communities who've been hit by multiple disasters - from the Black Summer bushfires, to extreme hail and storms.

"We've created the tracker to help communities understand that wild weather is getting more severe and happening more often. However, we can learn from these events and people can take practical steps to be better prepared, which could ultimately help save lives and property," Mr Gallagher said.

NSW SES Commissioner Carlene York said the tracker provides valuable insights for communities.

"By empowering communities to learn from past events, they can make changes that will go a long way to keeping them safe in future," Commissioner York said.

"Taking the time now to prepare can keep you, your family and even your animals safe when the next severe weather event hits.

"There are a lot of handy resources available on the NSW SES website that can help guide people in what they can do now."
