Stallone was not stopped from leaving Australia, where he spent the weekend promoting his latest movie, "Rocky Balboa," after officials searched his plane on the tarmac at Sydney airport on Monday, Sydney's The Daily Telegraph reported, without citing sources.

Officials are still examining substances collected from Stallone's entourage to determine whether further action would be taken, the newspaper reported.

Stallone and several people traveling with him were detained for several hours at Sydney airport on Friday as they arrived. Australian Customs Service national investigations manager Richard Janeczko said some contraband items were taken, but didn't identify them, reports AP.

Stallone initially said the detention on Friday was the result of a misunderstanding on his part, then later refused to answer questions about the incident.

In addition to illicit drugs, Australia prohibits the unlicensed importation of a wide range of steroids and performance-enhancing substances for sporting use. Penalties for possession of such substances can range from fines to prison terms.
