A five-year-old girl is in hospital after a freak traffic accident on the Gold Coast.

The girl was standing directly behind a cement wall at her home on Nineteenth Avenue in Palm Beach, when it was struck by a car around 11.30am on Sunday.

Part of the wall collapsed on the girl, seriously injuring her leg.

The 81-year-old female driver of the car was uninjured.

Police say the car had struck another car travelling in the same direction before losing control and hitting the cement wall.

Investigations are continuing.
