Outback town evacuated as floodwaters hit sodden state

Stephen Cowley's high-set Adavale home was the last residence in town still "high and dry" on Friday, yet he still chose to be relocated by SES crews to a nearby evacuation centre where he expects to remain for at least a week.

"We've been advised we should all leave town," Mr Cowley told AAP.

"The water has been rising the last three days. Last night there was a huge rise.

"At 4.30am it was running through our yards but now my truck and tractor is underwater, the four cars are gone."

Flood warnings have been issued across the state after days of downpours, with about 500mm recorded within a week at Adavale's neighbour Quilpie, representing a year's worth of rain.

A severe weather warning is current spanning the central west's Winton down to Cunnamulla near the NSW border.

Additional aerial support and swiftwater crews have been deployed out west to towns like Charleville and Longreach with more bound for Emerald on Friday.

"We are dealing with a significant event over a really large part of Queensland," Queensland Premier David Crisafulli said.

Widespread downpours of up to 400mm hit Queensland's west and southwest, with up to 200mm to come.

The wet weather has cut roads, isolated communities and disrupted telecommunications.

Quilpie locals said their plight had not been helped with no weather radar available between Alice Springs and Charleville and called for government support.

Quilpie Mayor Ben Hall said no radar meant the Bureau of Meteorology was "flying blind" and unable to provide his region a heads-up on when peak flooding would hit.

"It makes it very hard to coordinate emergency responses in times like this," he said.

"No forward planning for stock movement or anything else can happen without more accurate forecasting and we're still flying in the dark trying to work out what next for Quilpie Shire.

"It's heart breaking for farmers who were battling drought only a week ago."

The local towns inundated ironically include Eromanga, renowned as Australia's furthest town from the sea.

"We're working closely with the state (government) to look at if there's a need to fly in food supplies," Quilpie Council CEO Justin Hancock told AAP.

"It's too early to tell how long we're going to be cut off for to make the call."

A major flood warning has also been issued for the Haughton River near Townsville in north Queensland after downpours of up to 120mm, with more rain forecast.

The small town of Giru has been one of the worst hit, with the Haughton River 2.63m above the major flood level and rising.

The wet weather is set to move southeast by the weekend, bringing heavy rain as far down as northern and eastern NSW that may cause flooding.

Sandbagging sites are reopening around Brisbane and the Gold Coast, weeks after ex-Tropical Cyclone Alfred battered the southeast.
