A coast-to-coast cold front will roll across Australia from west to east from today.
Weatherzone reported that southern Western Australia would be among the most-affected regions from this morning.
A second cold front is forecast to hit the region from Tuesday, bringing heavy winds and rain, and spreading up the western coast by Wednesday afternoon.
That front will be followed by a chilly airmass keeping temperatures in the teens and even single digits.
It is set to roll across Australia to hit the east coast throughout the week.
Showers and winds are expected to hit the south and south-east.
And parts of Queensland and Victoria should brace for rain, starting from tomorrow.
Weatherzone said the chill temperatures could bring more snow to the alpine regions, which is good news for skiers.
Currently, many slopes enjoy respectable snow coverage, but the surface is hard rather than powdery.
Fresh falls could soften things.
Between 15-30cm has been forecast at this point for resorts by next weekend, as the east coast braces for the wintry snap.
Temperatures in Sydney will remain fairly consistent next week despite the approach of the cold front, ranging between roughly seven to eight degrees, up to 19 to 21 degrees.
Adelaide hit with city's wettest November day in nearly 60 years
Mid-week will be chillier, with a top of 17 forecast for Wednesday, while showers early in the week will clear up.
Things will be chillier in Melbourne, with temperatures unlikely to break out of the mid-teens, and intermittent rain and clouds.
Brisbane is also set to see rain early next week, but things will be warmer, rising to tops of 24 degrees by next weekend.
