Total losses from catastrophes since the start of the last bushfire season have raced past $4.5 billion, according to the latest Insurance Council of Australia (ICA) figures.

Losses from the bushfire catastrophe which hit NSW, Victoria, SA and Queensland have risen to $2.2 billion from more than 31,000 claims. About 36% of building claims are already closed, along with 70% of contents claims.

January’s hailstorms across NSW, Victoria, ACT and Queensland have generated losses of $1.2 billion from almost 108,000 claims, with about 15% of building claims and 15% of motor claims closed.

Losses from floods and storms in Queensland and NSW last month have risen to almost $677 million from 77,598 claims, while losses from a Queensland hailstorm in November are now estimated at $368 million from 25,000 claims.

Smaller fires in Queensland and NSW in September and October had combined losses of $56 million.
