Residents of the NSW east coast are coming to terms with the damage from the weekend's monster storms and destructive surf as Tasmania faces its worst floods in 40 years.
At least four people have lost their lives, three men are missing and several multi-million-dollar Sydney beachfront homes were teetering on the edge of collapse as they faced another night of king tides on Tuesday.
The storm may have abated but major flood warnings are still current in Tasmania and there are fears abnormally high tides could cause flooding and erosion in NSW.
Hundreds of homes and businesses suffered flood damage and farmers' crops have been wiped out in the wild weather, which has already resulted in $56 million of insurance claims.
Malcolm Turnbull and Bill Shorten agreed on an open-ended support package for victims on Tuesday as an insurance catastrophe area was expanded to cover the east coast of Victoria and Tasmania's northern and eastern coastlines.
The flooding in Tasmania has been described as the worst to hit the state in 40 years, with one person dead, two missing and more than 200 properties inundated.
Tasmanian search and rescue crews found the body of a 75-year-old woman on Tuesday, a day after her husband was winched to safety from their flooded Latrobe home.
An 81-year-old man swept into the Ouse River while feeding his sheep on Monday and a man whose car was swept away in Evandale on Tuesday remain missing.
Three men died in NSW and ACT during the storms, while the search is continuing for a man swept off rocks at Sydney's Bondi Beach, reported to be an American student studying at Sydney University.
The body of an unidentified woman was also recovered from the state's eastern suburbs on Tuesday afternoon.
Mr Turnbull and Mr Shorten both urged insurers to support storm-hit communities as they viewed the devastation first-hand on Tuesday.
The prime minister, who visited Picton southwest of Sydney with NSW Premier Mike Baird, said he was sure insurers would support the hardest-hit communities.
"This is very substantial storm damage," he said.
Mr Shorten, who visited Coogee, urged insurers to treat customers fairly.
"Make sure you deal with their claims in a speedy fashion," he said.
"For people who have suffered significant damage, the last thing they need is to be damaged again by a long argument with an insurance company."
