Flood victims get class action trial date

Victims of southeast Queensland's devastating 2011 floods have a trial date set for the largest class action in Australian history.

The class action for approximately 4500 flood victims will be heard in court on July 18, 2016, according to lawyers representing the victims.

The date was handed down on Thursday at the Federal Court of Australia to the relief of victims, who claim dam operators were negligent during the 2011 flood.

As the rain pelted down and water backed up, operators were forced to make large water releases to prevent Wivenhoe dam from collapsing.

The result was unnecessary flooding in Brisbane and Ipswich to the west, lawyers have claimed.

Previous estimates have suggested a possible compensation claim of $1 billion.

Maurice Blackburn principal Damian Scattini says the trial date may seem distant, but it's sooner than expected and there is a lot of work to do.

Many of the victims, he said, thought it would never happen.

The action was lodged in NSW because there's no class action regime in Queensland.
