Australia was home to all 15 of the world's hottest temperatures on Monday, with parts of south-east Queensland suffering its hottest March day on record.

The sweltering autumn day was set to be capped off with severe thunderstorms on Monday night, the Bureau of Meteorology warned.

Severe thunderstorms were detected on the weather radar near Coolangatta at the Gold Coast and north of Noosa Heads at the Sunshine Coast.

Both storm cells were moving to the north-east on Monday afternoon and were likely to produce damaging winds and large hail, according to a BoM warning.
