Snow has fallen in New South Wales and there have been reports of flurries as far north as Queensland, as a winter cold snap hits much of south-eastern Australia.

Some areas of Victoria copped 100 millimetres of rain overnight on Monday as a “windy, wintry blast” moved north from Tasmania into NSW and Queensland.

There were reports of snow at Shooters Hill in central NSW, on the Oberon Plateau in the Blue Mountains, and at Guyra in the Northern Tablelands.

Forecaster Weatherzone said snow flurries were also possible from Tuesday until Thursday in southern Queensland’s Granite Belt region “as a cold airmass originating in Antarctic waters crosses the border”.

“The chilly air will be accompanied by sufficient moisture for occasional light showers which could fall as snow on high ground above about 1000 metres,” Weatherzone wrote.

If there is snow in the Granite Belt, it will be the first fall in three years.

Well the cold weather and snow has certainly arrived. #RFS crews have been kept busy, with the Adaminaby Brigade attending several motor vehicle accidents across the Snowy Mountain region. In these cold and icy conditions it’s important you slow down and drive carefully. pic.twitter.com/cUnK5jdmAZ

It follows a wild night in Victoria, with more than 300 requests for help from the State Emergency Service. Most were for fallen trees, building damage and floods in the area east of Melbourne.

Flood warnings remained active across Gippsland and the Latrobe Valley on Tuesday.

Weatherzone noted a low-pressure system over the Tasman Sea had brought about 20 millimetres of rain to central Melbourne but 100 at Mount Sabine, near Apollo Bay on the Great Ocean Road, and 117 millimetres at Mount Baw Baw.

“[That was] the heaviest 24-hour total for the site in three years, some of which was snow but most of which was rain,” it said.

“The heavy Mount Baw Baw rain would just about have broken the heart of ski resort operators. Baw Baw’s advantage is being the closest ski destination to Melbourne, but its disadvantage – and it’s a biggie – is being the lowest mainland Australian ski resort.”

Weatherzone said other mainland snow resorts fared slightly better, with falls of 10 to 25 centimetres reported at the NSW resorts, as well as the northern Victorian resorts of Falls Creek and Mount Hotham.

North of the Murray, the NSW SES warned of damaging winds and blizzard conditions into Tuesday.

The Bureau of Meteorology cancelled an earlier severe weather warning but said it would continue to monitor conditions.

A sheep graziers warning for “cold temperatures, rain and showers and westerly winds” on Tuesday and Wednesday remained active for the following regions: Parts of the mid-north coast, Northern Tablelands, Illawarra, Central Tablelands, Southern Tablelands, central-west slopes and plains, south-west slopes and Snowy Mountains.

Elsewhere, Weatherzone warns that the crowd heading out for the State of Origin decider in Brisbane on Wednesday night should wrap up.

“If you happen to be heading to the game, it’ll be a cold night by Brisbane standards with a low of nine degrees with maximums of 19 degrees expected from Monday through to Thursday,” it said.

“Kickoff is at 8.05pm, at which time the apparent or ‘feels like’ temperature should be around 11 or 12 degrees in the stands. That’ll drop by a degree or two throughout the game even as temperatures rise on the field and in the coaching boxes.”
