About 90 millimetres has fallen over two days at Charlotte Plains, a 27,000 hectare station near Cunnamulla, about eight-and-a-half hours from Brisbane.

"It makes a huge difference to our stock. They'll be nice and fat and hopefully we'll be able to restock," station owner Robyn Russell said on Tuesday, noting prices would also likely rise.

"Everything will be so expensive we won't be able to."

Normally running between 8000 to 9000 head of sheep, Ms Russell said years of drought meant undergoing "dramatic destocking".

Currently she runs about 1500 head of sheep and 120 head of cattle.

"We could easily take about 400 head of cattle," she said.

She has been on the station for two decades and says this week's falls are the best she has seen for years.

"It certainly makes a difference to our sheep and cattle and the strain it puts on us when we're trying to keep them alive," Ms Russell said.

"I'm sure a lot of people are smiling."

The station has turned to tourism as a means of broadening revenue, and as well as relief the rain brought some extra work.

A tractor had been tasked with rescuing a bogged tourist on Tuesday morning.

Southern Queensland has been inundated by rain for several days as flash flooding cuts roads and closes schools in the east.

The Bureau of Meteorology is warning of possible flash flooding in Brisbane, Ipswich, Gold Coast, Toowoomba, Warwick, Stanthorpe, Kingaroy, Dalby, Goondiwindi, Roma, Charleville and St George.
