Celtic have begun life under Tony Mowbray successfully with a 3-0 win over Australian opposition Brisbane Roar at Suncorp Stadium.
A pretty big crowd of 31,340 saw Chris Killen snare two goals towards the end of the first half before substitute Koki Mizumo scored a brilliant diving header to take the game beyond reach for the A-League side.
Stand-in captain Scott McDonald was danger man for Celtic but was unable to score and was substituted on 61 minutes for new signing Marc-Antoine Fortune, who was making his debut and although not scoring looked lively and had some great touches on the ball.
The game wasn't perfect though as it was marred by three pitch invaders during the second half.
This was the first of four pre season matches until Celtic face their first UEFA Champions League test. Brisbane Roar will now face a number of domestic teams before they begin their A-League challenge.
A trophy was awarded to Celtic for winning and was presented by Queensland Premier Anna Bligh.
