It comes as the company that funded the legal action, IMF Bentham, estimates it will make up to $130 million from the case.

The Queensland government and dam operators were negligent in managing the deluge and damage was worse as a result, the NSW Supreme Court found on Friday.

Following the decision, the insurance industry said firms could be looking at the commercial implications of the flooding, for which they paid out $1.5 billion in claims.

Insurance Australia Group - whose subsidiaries include NRMA, RACV and Coles Insurance - told AAP on Monday it will not launch legal action to recoup from those at fault what it paid out to customers.

Suncorp Insurance declined to comment on the ruling.

Insurance Council of Australia spokesman Campbell Fuller said customers would not be in their sights for any potential legal action by firms looking to retrieve losses.

"Any action that insurers take from here won't affect what has already taken place between insurers and their customers," Mr Fuller told AAP.

"Anything insurers do from this point won't impact the customers from an insurance perspective."

It was up to individual companies to seek action, he said.

"The decision from the court named responsible parties so insurers will be examining that and determining their next course of action," Mr Fuller said.

"That will be on an individual basis - each insurer had a different level of exposure to the floods."

Queensland Attorney-General Yvette D'Ath said the government's legal representatives were still going through Justice Robert Beech-Jones' 1600 page judgment.

"It is taking some time to look through the judgment in detail," Ms D'Ath said on Monday.

She said the government was waiting on advice from its lawyers before forming any views about whether to appeal the decision.

She said some advice was expected back before the end of the week.
