Australia has experienced a tropical cyclone, snow, severe thunderstorms, and some unusually chilly evenings - and now we are in for another heatwave.

Residents should brace themselves for a heatwave that could reach as high as 40 degrees for the next five days across South Australia, south-west Western Australia and western Victoria.

Weatherzone however said the heatwave will not be as fierce as the one that hit Australia at the beginning of the year.
