Powerful storms packing giant hail and destructive winds have lashed communities in two states, cutting power to thousands of properties.

A series of severe thunderstorms brought wild weather to parts of NSW and Queensland on Saturday, the Bureau of Meteorology said.

More than 48,000 properties were without power in southeast Queensland at 7pm, according to Energex.

Large hail up to 6cm in diameter fell at Croppa Creek in northern NSW, with a 109 km/h wind gust recorded at nearby Walgett.

In southeast Queensland, more than 50mm of rain was recorded in 30 minutes at multiple locations and hail up to 7cm in diameter fell in the tiny town of Silverspur, about 60 km southwest of Stanthorpe.

Social media posts showed flash flooding events on the Sunshine Coast and in the Scenic Rim Region.
