Clean-up begins across Australia after wild weather leaves one dead

Extreme weather across three Australian states is expected to ease as the clean-up gets under way after strong winds left a woman dead, homes destroyed and towns on flood watch.

The wind and rain, which started on Sunday night, resulted in the death of a 63-year-old woman after a tree struck a cabin at a holiday park in Moama, on the New South Wales-Victoria border.

NSW police will prepare a report for the coroner following the woman's death after a tree landed on a cabin she was staying in at holiday park Merool on the Murray.

A man, also aged 63, was taken to hospital with minor injuries.

More than 120,000 Victorians were without power and 660 homes damaged on Monday following a night of pulsing winds and abnormally high tides.

The Bureau of Meteorology's senior meteorologist Sarah Scully said that while the worst of the weather had taken place, some damage was still to come.

"We're expecting the winds to gradually ease from the west ... and for all of the wind warnings to be cancelled by late (Monday)," she said.

"However, winds of this strength do have the potential to bring down trees, branches that may cause property damage, that may cause power outages and hazardous driving conditions."

Some low-lying properties in Tasmania may become isolated by flood waters and property, and livestock could be at risk from flood waters, according to the bureau.

Evacuation warnings have been issued for residents in the Derwent River, Meadowbank to Macquarie Plains and Styx River at Bushy Park to Macquarie Plains and surrounds.

In NSW, a bushfire near Wollongong closed the M1 Princes Highway while a second at Erskine Park in western Sydney closed two lanes on the M4 for several hours on Monday afternoon.

Another blaze was burning in Tomago north of Newcastle, with residents told to prepare their homes, before it was downgraded to watch and act.

A woman in her 50s suffered multiple injuries after being hit by a falling tree in Sydney's west.

Strong winds of up to 85km/h caused the cancellation of 90 flights to and from Sydney Airport and left just one of its three runways open.

The SES confirmed a home in Melbourne's Dandenong Ranges was destroyed along with a property in Corio in Geelong's north due to wind damage.
