A security screening of the aircraft was carried out after the men were discovered, and nothing suspicious was found on board, the AFP said A spokeswoman for Westralia Airports Corporation, owners of the airport, said it would make no comment on the incident until a meeting of bosses had concluded. A Qantas spokeswoman also said the company had no comment on the security breach.
