Payouts for victims of the 2011 Queensland floods are being delayed because just 1 per cent of claims involved in the long-running class action cannot be finalised.

In an update to more than 7,800 claimants, which has been seen by the ABC, those involved in the court case were told final sums will now be paid between July and September this year.
