GAV’S WEATHER | COOL CHANGE MOVING IN

Autumn has settled in for good with a cold burst of polar air cooling much of South-East Australia.

On Thursday, it will be mostly fine thanks to a large high pressure system.

But hold on to your hats, the high will generate onshore winds, cooling much of the East Coast.

West of the divide, expect it to remain fine.

Elsewhere, Cyclone Wallace will remain well off the Pilbara Coast.
