Mandatory evacuations have been declared for the inland Queensland town of St George as it braces for a record flood to hit.
Authorities made the call on Sunday afternoon based on modelling by the Bureau of Meteorology.
The modelling shows that upstream rivers are rising quickly and the Balonne River is now expected to peak in St George anywhere between 14 and 15 metres.
The devastating flood that tore through the town in 2010 peaked at 13.5 metres.
Residents are being told to leave town along the Moonie Highway before it is cut by floodwaters, which is expected early Sunday night.
Buses will also leave from the St George Showgrounds for evacuation centres set up in Dalby.
Extra police will patrol the town to deter looters.
Air evacuation to Brisbane is being organised so evacuations can proceed after the Moonie Highway closes.
Queensland Premier Anna Bligh has urged residents to follow directions.
'This is a very serious situation and I urge people to cooperate,' she said.
Mayor Donna Stewart said residents should evacuate willingly for their own safety.
