Josh Giddey is on an Olympic collision course with NBA teammate Shai Gilgeous-Alexander, with the Boomers learning who their opponents will be in the pool stage in Paris.

The Olympic men's and women's basketball draws were conducted in Switzerland on Wednesday morning AEDT, with the Boomers receiving no favours as they look to defend a historic bronze medal won in Tokyo three years ago.

The Boomers will play World Cup bronze medallists Canada, as well as qualifiers from two July tournaments that could include Greece, Slovenia or Spain in a stacked Games pool.

In the women's competition, the Opals — ranked number three in the world — will play Canada, France and Nigeria, ranked fifth, seventh and 12th in the world respectively.

Canada's men have not qualified for an Olympics since Sydney's 2000 Games.

But they will be among the favourites after Oklahoma City Thunder weapon Gilgeous-Alexander led them to bronze at last year's World Cup, toppling the US in the medal game.

The team will be brimming with NBA talent, with Jamal Murray, RJ Barrett, Kelly Olynyk, Dillon Brooks, Luguentz Dort and Dwight Powell all likely to suit up.

Giddey became the Boomers' focal point at last year's World Cup, leaving coach Brian Goorjian with some tough decisions ahead on how to best mix his emerging NBA talent with Patty Mills and Joe Ingles, who are set to play in a fifth Olympics.
