Photos: First snow at Australian ski resorts for 2018

A cold snap across south-eastern Australia has seen the first major snowfalls of the year arrive in the Alps with 15cm of snow recorded at Mount Hotham in the past 24 hours, and 16cm at Mount Buller.

Mount Buller was running its snow guns on Thursday night on its Bourke St ski run.

More significant snow is expected to fall on Friday as the cold weather continues.

In NSW, rugged-up residents in the NSW central west have woken up to a blanket of snow as a cold snap sweeps through the state.

A light dusting of snow covered the Central Tablelands overnight, with higher mountain peaks receiving a few centimetres, according to the Bureau of Meteorology.

"We are expecting the snow to be done with by this afternoon and anything on the ground is likely to melt away," BOM spokeswoman Anita Titmarsh said.

A complex low-pressure system near Tasmania is to blame for the sudden winter chill as it brings wind and cold weather to much of south-east Australia.

Thredbo Resort spokesperson Suzie Diver said Thursday night's snowfall is a good base ahead of the ski and snowboarding season when it opens on June 9.

"It is always nice to see a bit of snow falling in the village and colder temperatures this time of year," Ms Diver said.
