Canada was never behind and outscored Australia 23-13 in the final quarter to earn a 90-70 victory Friday in Perth in a pre-season game at the World Cup.
The Canadians led 51-36 early in the third quarter when the Australians pulled together to return to a tie. They then mastered the last commitment to secure an easy victory.
The two teams will meet again Saturday at the stadium of Perth. Australia also has an appointment with Canada in their first World Cup match on September 1 in China.
Canada participates in the World Cup without most of its NBA stars. Kelly Olynyk of the Miami Heat is the last leading player to retire due to a knee injury.
The team was already without Andrew Wiggins, Jamal Murray, R.J. Barrett, Tristan Thompson, Dwight Powell, Shai Gilgeous-Alexander, Chris Boucher and Nickeil Alexander-Walker.
Kevin Pangos scored 18 points for Canada, led by coach Nick Nurse, NBA champion with the Toronto Raptors.
Andrew Nembhard added 12 points and is among the five players to have collected at least 10 points for the winners.
Patty Mills led Australia's attack with 20 points.
