Thousands of southeast Queensland flood victims have had another win with the state government deciding not to appeal a landmark class action decision.
Attorney-General Yvette D'Ath said on Thursday they wouldn't appeal the NSW Supreme Court's ruling in favour of 6800 claimants who sued the government, Seqwater and Sunwater over the scale of the 2011 flood disaster.
However she noted the decision was "separate to any action that may be taken by other parties to the NSW Supreme Court decision".
Maurice Blackburn principal lawyer Rebecca Gilsenan welcomed the announcement but said for her clients to promptly get the compensation they deserved, a "whole-of-government approach" was needed.
"It will make little difference to the situation of the people of southeast Queensland if the state doesn't appeal, but state-owned entities Seqwater and Sunwater do appeal," she said in a statement.
Former Ipswich councillor and claimant Paul Tully said his community was overjoyed.
"Premier Palaszczuk should be congratulated for her decision to draw a line in the sand and put an end to this costly litigation," he said in a statement.
The NSW Supreme Court in November ruled flood victims were failed by engineers who negligently operated infrastructure built to save them from the kind of "biblical" deluge that fell upstream of Brisbane and Ipswich in January 2011.
Justice Robert Beech-Jones found claimants suffered worse flood damage because engineers did not properly manage the two dams during an extraordinary rain event.
