Falls of up to 300mm to drench eastern Australia

Australians are advised to keep their umbrellas handy, with falls of up to 300 millimetres expected for parts of eastern Australia in the coming days.

Weatherzone meteorologist Joel Pippard told nine.com.au that two troughs off the eastern coast would make it a wet week for parts of Queensland and NSW.

The heaviest falls will come in northern Queensland, between Cairns and Townsville, Mr Pippard said.

"It's pretty likely that over the next few days, say until Thursday, there will be isolated rainfalls of up to 150-300mm there," Mr Pippard said.

"It is Australia's wettest region though."

A southern coastal trough off the shores of southern Queensland and northern NSW is set to bring lighter but more widespread rain to both states.

Mr Pippard said between Hervey Bay and Sydney there would be falls of five to 10 millimetres, along with isolated heavier showers bringing 30-50mm.

But although widespread from north to south, he said the weather wouldn't roll inland.

"It's not making it further than the Great Dividing Range," he said.

The heavier showers are likely to be extremely localised.

Yesterday, 31mm fell at Williamtown, Newcastle, while surrounding areas received just one to two millimetres.
