Actor Johnny Depp has flown back to the United States from Queensland's Gold Coast for surgery on an injured hand, the Australian publicist for Pirates of the Caribbean 5 says.

The publicist said Depp left Australia today.

However, the publicist would not say how Depp hurt his hand, nor when he might return.

A report in an online magazine said Depp injured his hand on the weekend, but the actor was not working on the set or filming at the time.

Filming for Pirates of the Caribbean 5: Dead Men Tell No Tales, began in February at a set built on a secret location in the Gold Coast hinterland.

The Federal Government spent $21.6 million to secure the production for Queensland, while the State Government offered an incentive package that included payroll tax concessions.

Queensland beat several other Australian states and Mexico to host the production.

Last year, then-premier Campbell Newman said the film - the largest ever shot in Australia - would inject $100 million into the state's economy and create thousands of local jobs.

Pirates of the Caribbean 5 is slated for worldwide cinema release in July 2017.
