Storms that ravaged parts of NSW, Victoria, and Tasmania last week are likely to result in an insurance bill of more than $120 million.

The Insurance Disaster Response Organisation (IDRO) says insurers had dealt with about 30,000 claims late last week, with more expected as policyholders discover less obvious damage.

The storms on Tuesday and Wednesday uprooted trees, damaged houses and businesses, destroyed cars and caused power shortages.

IDRO National Co-ordinator Chris Henri says NSW was the worst hit, with about 15,000 claims valued at $75 million. Victoria had about 12,000 claims ($40 million) and north-eastern Tasmania had about 2000 ($5 million).

Mr Henri says the damage bill is likely to go much higher, but insurers can cope.

“We expect the figure will be boosted by commercial claims, which take some time to assess. However, these figures do not take into account the recoveries that insurers may make through their reinsurance arrangements.”

CGU says it received more than 1100 claims by early Friday and had to roster on extra claims staff to deal with calls. But the IAG subsidiary told Sunrise Exchange News it is too early to estimate the effect in money terms.

Promina says it is too close to results time to comment on the financial effect of the storms.
