Towns around the southeast Queensland city of Bundaberg could spend up to two days without power after five tornadoes wreaked havoc in the area on Australia Day.

Burnett Heads and nearby Bargara were declared disaster areas after twisters ripped through the coastal townships from 1pm AEST on Saturday, injuring a total of 17 people and damaging more than 150 homes.

Two people were critically injured when a giant pine fell on their parked car on the Esplanade at Bargara, while two homes were completely destroyed in the mini-cyclone that struck Burnett Heads.

Authorities said Burnett Heads was again struck by the latest in the series of twisters, which hit the area at 6pm AEST and 6.30pm.
