Pantelis took advantage of a poor clearance by goalkeeper Paul Henderson to fire the visitors in front on the hour before Leckie curled in an excellent second at the death.

Iain Fyfe also hit the post for the visitors.

North Queensland dominated the first half, threatening with eight shots on goal and four corners, but lacked the finishing touch required to find the back of the net. Adelaide were restricted to their own half for most of the first period.

 Fury's Daniel McBreen looked guaranteed to score early when he lashed at a loose ball in the box with only one defender in his path but the shot was wide of the post.

Robbie Fowler then forced a save form United keeper Eugene Galekovic.

The strikers combined late in the half with McBreen charging down the left wing with Fowler on his inside but in a communication meltdown the marquee man let the ball roll behind him thinking it was meant for a team-mate.

United had their first real chance of the night straight after the break when Cassio forced a turnover on the wing to set up Pantelis but the striker could not get a shot away

A clumsy clearance from Henderson fell straight to an opponent who laid the ball off to an unmarked Pantelis to open the scoring in the 60th minute with a thunderous strike from outside the box.

Iain Fyfe almost doubled the score just minutes later but thudded his shot off the post.

Dyron Daal was injected into the game from the bench and almost had an immediate impact when he used his height to meet a cross but his header was off target.

Daal won a midfield highball with another header into the path of a rampaging Jason Spagnuolo who brought McBreen into the frame but the striker again pushed his shot wide of the goal.

Leckie then sealed the game when he dribbled through sloppy defence stepping around the final defender to slot the final nail in Fury's coffin in injury time.
