Brisbane has recorded its wettest 24 hours in more than half a century and its fifth-wettest day on record, but meteorologists say the rainfall is set to ease on Monday in south-east Queensland and northern NSW.

About 275.2mm of rain fell in the 24 hours to 9am on Monday - a level not seen since 314mm fell on 26 January 1974, the same year the Brisbane River flooded in the wake of Tropical Cyclone Wanda.
