The Condamine River at Condamine on Queensland's Western Downs is expected to peak later today but authorities say no homes in the town will be inundated.
The river is expected to reach a major flood height of at least 11 metres, cutting the main bridge.
The Western Downs council says roads to the south and east will remain open.
The town was evacuated twice in 2010-2011 when the river exceeded record levels of 13 metres.
