About 2,000 Queensland flood victims are eager to join a potential billion-dollar class action against the state government, lawyers say.

Maurice Blackburn lawyers and litigation funder IMF met flood victims in Ipswich, Fernvale, Chelmer and Wacol on Saturday and Sunday.

They are investigating the potential for a class action against the state government over claims that the government-owned Wivenhoe Dam operator mismanaged water releases, exacerbating the flood.

IMF executive director John Walker told AAP on Sunday that more than 700 home and business owners attended the meetings.


"They are devastated and are looking for an avenue to minimise the effects of the flood," Mr Walker said.

About 2000 Queenslanders have expressed interest in being part of a class action, Mr Walker said.

The lawyers are waiting for the flood inquiry's final report into whether the dam operator was at fault, which is due on Friday.

Maurice Blackburn principal Rod Hodgson said the next step was to scrutinise the inquiry's report.

"We are expecting the contents of the report will go some way in assisting us in making decisions," Mr Hodgson said.

"We won't rely solely on what the inquiry determines as we will conduct some of our own analysis."

Another meeting with flood victims is being planned for March 19 at Goodna, in Ipswich.
