Police will remain in Burketown, in the Gulf of Carpentaria, overnight after the last evacuations of the flooded town were carried out on Saturday.
The majority of the town's 150 residents were flown to neighbouring communities amid the worst flood ever seen in the region.
Police said no further evacuations were expected to be carried out after Saturday but if emergency rescues were required they could be arranged.
"In total we've moved about 88 people back to Mount Isa via trips by helicopter to Doomadgee and then by plane back to Mount Isa," said Superintendent Tom Armitt of the Queensland Police.
"A small contingent of about 60 will be remaining in Burketown. There is a contingent of police that will remain in Burketown overnight for safety reasons.
"Tomorrow helicopters will remain on stand-by for rescue operations if required."
While power remains on in dry areas, floodwater was creeping toward the power station.
Sewerage systems were compromised.
"We just ask that you remain in place," Superintendent Armitt said.
"If you do feel that your safety is being threatened please contact the local police in Burketown and we'll make arrangements for your safety."
At least 65 millimetres of rain fell in already saturated catchments for the Nicholson and Leichhardt rivers in the 48 hours to 9am Saturday, according to the Bureau of Meteorology, which had issued a major flood warning.
The Albert River at the Burketown airstrip swelled higher than seven metres on Friday afternoon, exceeding the 2011 record flood level of 6.78 metres.
Bureau of Meterology Senior Meterologist Harry Clark said the Burketown peak was expected on Sunday and "it's going to be quite a prolonged peak" staying high for days.
"We're seeing record-breaking flood levels through the north-west of the state currently and with major flooding ongoing for the Leichhardt, Nicholson and Gregory river catchments as well as the Flinders river catchments," he said.
Mr Clark said the rain system was spreading into southern and central Queensland.
"We are seeing the rain push into much of the Darling Downs and Maranoa and Warrego and eventually it will push into the south-east coast later this afternoon or this evening," he said.
"Not expecting to see the same intensity of rain that we saw in the north-west of the state … but certainly could see some isolated heavy falls with thunderstorm activity."
'Up to their necks'
Fourth-generation Burketown resident Shannon Moren was evacuated with her three daughters to Mount Isa on Friday.
She said there was concern about loss of cattle from the grazing properties across the region.
"I checked on my parents' cattle property the other day and you can see cattle up to their necks in the water, literally swimming for their lives," she said.
"You can see some of the bodies floating on the water.
"It's really distressing."
Ms Moren said the flood was the worse she had seen in the region.
"We're used to floods out here," she said.
"But in my lifetime I haven't seen this, my parents haven't seen this."
Disaster assistance available
Telstra continued to try to restore phone services that had been out intermittently in the Gregory region this week, but efforts were hampered by demand for helicopters.
Disaster assistance was made available to residents and councils impacted by the widespread flooding across the gulf region.
Residents could access payments of up to $180 for individuals and up to $900 for a family of five to cover the costs of essential items such as medicine, food and clothing.
Councils would receive financial support to cover the cost of disaster operations and the clean-up.
