The most recent autumn in Canberra was the most destructive in almost five years, with nearly half of insurance claims made in the season due to extreme weather.
New data released on Thursday by insurer NRMA revealed there were 272 claims made in the territory in the past three months due to severe weather events, with 259 of those being for storm damage.
Of all claims made in Canberra during autumn, 43 per cent were due to severe weather, significantly more than the ACT average of 33 per cent for that time of year.
Suburbs in Canberra's south were significantly impacted due to the wild weather, with areas including Gordon, Kambah, Isabella Plains, Monash and MacGregor the hardest hit.
NRMA executive general manager of direct claims Luke Gallagher said the insurer had noticed a large increase in recent years of claims due to extreme weather events not just in the ACT but along large parts of the east coast of Australia.
"We used to say that storm season lasted from September to March or April, but that doesn't exist any more and storm season can happen at any point in time," he said.
"The last 18 months have seen an increase in the frequency and severity of weather events, and you only have to look at the Black Summer bushfires and the hailstorm all occurring close together."
Across the ACT, NSW and Queensland, the number of insurance claims due to extreme weather has almost tripled in the past five years, with more than 15,700 claims in the past season in the three jurisdictions alone.
The past autumn was marked by heavy flooding across eastern Australia, with areas in Sydney's north-west and the NSW north coast most heavily affected.
Parts of Canberra also experienced heavy flooding during that time, which closed off large parts of the Namadgi National Park, with emergency crews having to rescue multiple Canberrans who became trapped in rising waters.
The NRMA data also revealed that 79 per cent of Canberrans surveyed were worried that severe weather and natural disasters were becoming more frequent and more intense.
Mr Gallagher said while high numbers of those surveyed have expressed concern about natural disasters, a lower number of people had prepared their property for such an event.
"While 79 per cent have expressed concern, less than 50 per cent of Canberra residents are ready or have shown some form of preparedness, which equates to about 73,000 houses," he said.
"If the past 18 months is anything to go by, there will be more severe weather events in the south of NSW and in the ACT."
