Australia picked up gold in the wheelchair rugby yesterday with a 66-51 win over Canada at the Basketball Arena.
USA took the bronze medal with a 53-43 win over Japan, while Great Britain, who managed fourth in Beijing, finished one place lower.
Canada, semi-final conquerors of 2008 Paralympic gold medallists the United States yesterday, had no answer to Australia's greater speed and organisation.
The silver medallists from Beijing went one better this time around, ending the five-day tournament as the only unbeaten team, with Ryley Batt cementing his reputation as the world's best player.
The 23-year-old, appearing in his third Paralympics, scored 37 goals to give him a remarkable tally of 160 from his five tournament 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.
Meanwhile, a second-half strike from Eduard Ramonov was enough to give Russia a 1-0 win over Beijing champions Ukraine in the 7-a-side football at the Riverbank Arena.
In the last available medal event at the Games, the sides cancelled each other out for large periods of the game before the breakthrough came in the 44th minute, giving Russia their 36th gold of the Paralympics and a second place finish overall – just ahead of Great Britain in third.
Ukraine's silver saw them leap-frog Australia into fourth place overall in the medals table, setting their best ever tally since first competing in 1996.
Iran also finished their Games with a new record haul of 24 medals, making up the honours in the football with a convincing 5-0 win over Brazil earlier on in the bronze-medal match. Great Britain finished seventh after a 3-1 win over the United States, while the Netherlands claimed the fifth classification place with a 3-0 win against Argentina.
