Johnny Depp is set to leave Australia in the coming days, but the publicist for the Pirates of the Caribbean says there is no truth to reports he is fleeing to resurrect his marriage.

There has been extraordinary attention on the movements of 51-year-old Depp, who has been filming the fifth instalment of Pirates on Queensland's Gold Coast.

News Corp reported on Thursday that Depp had walked off set and and was planning to head back to the United States because of relationship problems with wife Amber Heard.
