Tom Rogic will have the chance to play in the Scottish FA Cup final next month.
The Caltex Socceroos star has come off the bench in Celtic's 2-0 win over Rangers in their semi-final at Hampden Park.
Rogic was introduced with 15 minutes remaining and struck the post with a late effort from outside the box.
Callum McGregor and Scott Sinclair scored Celtic's goals in front of 50-thousand fans.
Celtic will meet Aberdeen in the final in late May.
