Snow and heavy rainfall: Parts of Australia battered by wild weather

There have been more than 700 calls for help and 13 flood rescues in the past 48 hours as rain batters the NSW South Coast.

Up to 200mm of rainfall hit a number of towns including Moruya, Nowra and Captains Flat over the past 24 hours, and the bad weather is likely to linger in NSW until Tuesday.

In the 24 hours leading up to 9am Sunday, Wattamolla received 132mm while nearby Hampden Bridge got 128.

More than 20 homes at Broughton Vale near Berry were also cut off by floodwater after more than 200mm of rain fell in 24 hours, NSW SES said.

Flood warnings associated with the low pressure system have been issued for the Shoalhaven, St Georges Basin, Deua, Moruya and Bega rivers, while flooding along the Snowy River and the Queanbeyan River has not been ruled out.

Photos of the Oallen Ford Bridge, which crosses Shoalhaven River, show it completely covered in water.

Sussex Inlet, which only a fortnight ago had homes evacuated due to flooding, is also under a flood warning from the Bureau of Meteorology with the tide expected to peak at midnight.

Severe weather warnings have been issued on Sunday for a large stretch of the NSW coast from Moruya to Kempsey, taking in Wollongong, Sydney and Newcastle. Heavy rainfall, damaging winds and very heavy surf are expected.

"Residents are waking up to a changing landscape," NSW State Emergency Service deputy incident controller Allan Budziarski said in a statement on Sunday.

"We remind everyone, whether you are a local or just passing through, never walk, ride, drive or play in floodwaters.

"The rain is expected to remain around until Tuesday but we urge drivers, especially those travelling along south coast NSW, to take care while on the roads, drive to the conditions."

Disaster assistance has been made available to those impacted in the local government areas of Bega Valley, Eurobodalla, Kiama, Shellharbour, Shoalhaven and Newcastle.

The NSW SES encourages those dealing with the heavy rainfall to move vehicles under cover, secure loose items around their homes and keep at least eight metres away from fallen power lines.

Meanwhile, in Orange in NSW’s Central West, residents on Sunday morning were treated to snow flurries.

Temperatures in Orange are expected to peak at just 6C on Sunday with a minimum of 1.8.

At 9am on Sunday, it sat at just 2. It’s been a chilly week in the town too – last Sunday it fell to -4.2.
