Australia is keeping mum on reports it partnered with Lebanon for more than a year to monitor a plot to blow up a flight from Sydney to Abu Dhabi.
Transport Minister Darren Chester, who has primary responsibility for Australia's airports, was reluctant to confirm statements by the Lebanese Interior Minister.
"The bottom line is we work very closely with our security partners around the world," Chester told Sky News today.
"It's a team effort in the sense that we do need to share information, because the threat of terrorism crosses international boundaries."
Australian police this month charged Khaled Khayat and Mahmoud Khayat with two counts of planning a terrorist attack after conducting raids to disrupt what authorities described as an Isis-inspired plot to bomb an Etihad Airways flight.
