Australia's bid to defend their Asian Cup crown began in miserable fashion as they slumped to a shock 1-0 loss to Jordan in Al Ain on Sunday.
Anas Bani Yaseen's bullet header midway through the first half gave the unfancied underdogs a hard-earned and entirely deserved victory in the opening fixture of Group B.
Though content to sit back and counter, Vital Borkelmans' men forced Mat Ryan into regular saves and could have had a second to celebrate if not for a fine save from the Brighton and Hove Albion goalkeeper.
Awer Mabil also tested the woodwork late in proceedings, while Jamie Maclaren had a goal ruled out for offside, but concerns over Australia's ability to replace the goals of the retired Tim Cahill are threatening to linger throughout the tournament.
