After being battered by strong winds, heavy rainfall and even snow in some parts, New South Wales and Victoria will shiver through another icy day on Wednesday.
Sydney is forecast to reach a maximum of just 16C - a little higher than Tuesday's 10.2C - but the wild weather is set to continue prompting a warning from the State Emergency Service.
Melbourne will see highs of just 14C, with Adelaide at 15C and Hobart at 12C.
SES volunteers had responded to more than 350 calls for help from the public by Tuesday evening and thousands of homes have lost power.

'The worst-hit area was Orange, where a narrow part of the town bore the brunt of the damaging winds, which resulted in roof damage and fallen trees,' the SES said in a statement.
The Bureau of Meteorology said a low pressure system is expected to remain offshore and track slowly east over the next few days, generating vigorous winds and seas over the central and southern coastline.
BoM on Tuesday issued a severe weather warning for damaging winds which they said could reach up to 120 km/h along parts of the coastline in the state's south.
Closer to Sydney, the Bureau said wind speeds averaging 60 to 70 km/h with peak gusts in excess of 90 km/h are probable along the coastal fringe of the Sydney Metropolitan, Illawarra and northern parts of the South Coast districts.
Nearly 140 of the calls to SES came from the Sydney area on Tuesday.
In the Blue Mountains the cold winds brought snow for Jenolan and Blackheath with more expected on Wednesday.

While on the coast a hazardous surf warning has been issued for the Hunter, Sydney, Illawarra, Batemans and Eden beaches with people advised not to go fishing, swimming or boating.
Surf Lifesaving NSW added that anyone thinking the swells might provide good surfing or fishing conditions should exercise caution.
'With the current COVID environment our resources aren't committed to actively patrolling until mid-September, so if you take a risk and find yourself in trouble there could be a delay in response in getting emergency services to the scene,' a spokesperson said.
