Highway shut as Qld flood waters rise

Floodwaters in a rural Queensland town have shut a main highway and are expected to continue rising throughout the week.

The town of St George - about 500km west of Brisbane - is expecting the Balonne River to peak at about 12.5m late on Wednesday or early Thursday.

The river has risen to 11m and is over the Andrew Nixon bridge, which connects communities in regions west of the town.

Downpours across the state's southwest last weekend have resulted in several towns experiencing flooding.

Homes along the river are at risk of moderate flooding and sandbags have been prepared, says Balonne Mayor Richard Marsh.

The town's main water supply, Breadmore Dam, is overflowing after sitting at just six per cent at the start of February.

The floodingis expected to hit the town of Dirranbandi - about 100km south of St George - on Friday.

The Balonne River flows into the Murray Darling system.

Brendan Sweeting, who is manager of The Dirran Pub, said there has been a positive attitude around the town which has been crippled by drought in recent years.

"They are all pretty upbeat here because it has been so dry for so long," Mr Sweeting told AAP.

He said farmers were now talking about what they were going to plant, rather than wondering when rain will come.
