Orange has been painted white and Sydney is shivering through its coldest day in more than 25 years as much of eastern Australia is shrouded in a winter storm.
A cold air mass has blown in from Antarctica, sending temperatures plummeting and widespread snowfall all the way up to the Queensland border.
Towns near Orange in NSW have been turned into a "winter wonderland", meteorologist Gabrielle Woodhouse told reporters.
"The Central Tablelands is where you're seeing some of the most significant snow falls and there's some pretty impressive imagery out there," she said.
Orange appears to have copped up to 15cm of snow, while half a metre was dumped on the NSW slopes.
Even places like Inverell and Coonabarabran, which are only around 500m above sea level, have received a dusting.
"It's quite pretty to look at but it can also pose quite a risk," Ms Woodhouse said.
More than 500 homes across the state are without power due to weather damage, a number of roads have been closed, and temperatures are generally at least 10 degrees below average.
Several locations look set to break records for the coldest maximum temperatures in years.
It is so far the coldest day in Sydney for at least 25 years, potentially since 1984, Ms Woodhouse said.
However, the icy blast will begin to move offshore during Friday, likely meaning Thursday is the last chance for snow chasers to catch the spectacle outside the alpine regions.
