More than 25,000 homes and businesses were left without power after storms across south-east Queensland on Monday afternoon.

Hailstones up to three centimetres were reported as the first of the forecast severe storms hit.

It comes after almost two weeks of heatwave conditions across the state, driving temperatures as high as the mid-40s. 

These conditions have driven very high and severe fire danger ratings for parts of Queensland’s south, east coast and central interior as firefighters continue battling blazes threatening populated areas of Fraser Island.
