Overnight, residents in low-lying areas of the Lockyer Valley, west of Brisbane, were urged to evacuate as Laidley Creek continued to rise.

Mayor Ron Dyne says the Kidd Bridge was cut overnight and the Normanby Bridge was expected to be flooded.
Councillor Dyne says at this stage, homes are unlikely to be affected.
"We are expecting a high of 13 metres at 11 o'clock to 12 o'clock tonight and about 16 metres by nine o'clock tomorrow morning," he said.
"Now 16 metres indicates that some businesses in the CBD will be impacted by water because they'll go in at 15.1 metres."
Emergency services are urgently calling on motorists to avoid non-essential travel and not to cross flooded roads in the state's south-east.
