Tornadoes and a thunderstorm "supercell" have swept across Queensland in Australia, injuring four people and causing widespread damage.

The dangerous weather system hit the state's south-east on Thursday, the Bureau of Meteorology (BOM) said.

One tornado struck Tansey, a town 250km (155 miles) north of Brisbane, snapping trees and ripping roofs from houses.

Elsewhere, four people were injured when tennis ball-sized hail shattered car windscreens, authorities said.

One, Fiona Simpson, posted images online of bruises and scrapes across her body.

"I covered my infant with my body to stop her from getting badly injured.... never drive in a hail storm," she wrote of the incident in the town of Kingaroy.

Local man Steven Harland described the storm as "pretty intense", telling the ´óÏó´«Ã½ he had seen "flash flooding, countless trees down, and damage to vehicles from the hail".

"It's just a reminder what Mother Nature can do in such a short period of time," he said.

Authorities said they had fielded more than 300 calls for help, including for a driver trapped by a fallen tree.

Almost 10,000 properties remained without power on Friday, the Australian Broadcasting Corporation reported.
