Thousands registered, but no timeline for flood class action A map showing which parts of southeast Queensland should not have flooded (in green). Yellow marks parts that would have got 6 inches or more. Almost 5000 people have registered for a class action over the 2011 floods but there is still no timeline for when it could be launched. Maurice Blackburn, the law firm behind the class action, has had just under 2500 sign up to the proposed lawsuit and 4800 people have registered their interest. There are hopes the class action could yield up to $500 million for people whose homes flooded - something Maurice Blackburn argues should not have happened if Wivenhoe Dam had been operated properly. "Work on the class action is building strongly, and as in any lawsuit of this size, there is much to do to ensure that the evidence is properly in place before we file," principal at Maurice Blackburn Lawyers, Damian Scattini, said. We now have over 4800 registrants, and will be looking to hold more public meetings soon to update people. The action will be filed following completion of the work required for the case to be undertaken over the coming months. The law firm has not spoken publicly about the class action since it unveiled flood maps that it claimed showed the houses and properties which should not have flooded. It later admitted it would not be use the maps in any court case and they had been used to publicise the case. The law firm held a series of public meetings last year to drum up interest and is planning to hold another series in the coming months. The action is being funded by IMF which is expecting to invest about $10 million but it is conditional on enough flood victims being recruited with a certain dollar amount of damage done to their homes.
