The bus carrying all of Britney Spears' tour equipment has been involved in a serious accident in Australia - the vehicle flipped off the road during a bad storm.

The Toxic hitmaker is currently touring Down Under with her Circus shows and her equipment bus was travelling to Melbourne on Thursday (26Nov09) ahead of her concert at the Rod Laver Arena on Friday night (27Nov09).

Police reports state the accident occurred in Parkes, New South Wales after strong winds whipped the truck off the road.

The driver was admitted to hospital, where his condition is unknown as WENN went to press. All of Spears' equipment was undamaged, according to TMZ.com.

Spears was not involved in the accident and is expected to take the stage as scheduled on Friday night.

The news comes just days after Miley Cyrus' tour bus was involved in a fatal accident in Virginia, which left the driver dead and nine members of her crew injured.
