Canada had no answer to Australia's greater speed and organisation. And they did not have a clue how to cope with Batt, who cemented his reputation as the world's best player in a 66-51 win.

The 23-year-old, appearing in his third Paralympics, scored 37 goals to give him a remarkable tally of 160 from his five tourrnament starts.

Canada were effectively out of contention by the end of the first quarter, when they trailed 18-11, and Australia required no second invitation to turn the screw.

The silver medallists at Beijing 2008 went one better this time around, ending the five-day tournament as its only unbeaten team.

They collected Australia's 32nd gold medal of the Games, and 85th in total.

The USA, reigning Paralympic Games champions and world number ones, won bronze after recording a comfortable 53-43 victory over Japan.

Chuck Aoki inspired them to victory, with his 13-goal haul - backed up by 10 from Joe Delagrave - ensuring Japan were always up against it.

Although they only lost the opening two quarters 12-11 and 12-10, Japan conceded a crucial five-goal advantage in the third quarter that condemned them to defeat despite 27 goals scored by Ikezaki Daisuke.

USA coach James Gumbert said: 'I'm overwhelmed, they lived our model "together as one", and they went out there and said "we're going to leave it all out there for each other". As a coach, that's all you can ask for your team.'
