The Queensland city of Gympie has been cut off by floodwaters which saw the Mary River peak just above 16m overnight, as storms yet again batter the state.
More than 100mm fell overnight in parts of the south-east, leading to properties being flooded yet again.

They were also warned, along with residents of Ipswich and Logan, to conserve water due to major issues at the Mount Crosby Water Treatment Plant.
