Australia will boast four NBA players - but just one from its domestic league - at this year's basketball World Cup in Spain.

Boomers coach Andrej Lemanis on Monday announced his final 12-man squad for the tournament, beginning next month, headlined by San Antonio Spurs NBA title-winner Aron Baynes, Cleveland Cavaliers guard Matthew Dellavedova and 2014 draftees Dante Exum (Utah Jazz) and Cameron Bairstow (Chicago Bulls).

Adam Gibson from the Adelaide 36ers is the only NBL star in the team, with four others cut from the initial 17-man squad following a training camp in Canberra.

Surprisingly, one of Australia's brightest young talents - and son of a former NBL import - Ben Simmons, also missed on a spot.

"Really disappointed didn't make the Worlds Team, Good luck to all the guys who did #grindtime," Simmons, considered a future top-two NBA draft pick, wrote on Twitter.

Six players will be making their major tournament debuts for the Boomers, including Bairstow and Exum, as well as NBA prospect Brock Motum.

Three-time Olympian David Andersen will go around for his fifth major international tournament for Australia, alongside fellow experienced leaders Joe Ingles and Brad Newley.

Lemanis said the final team selection was challenging, given the depth of talent now available.

"I have always said that difficult decisions would need to be made, and it was very tough as a staff to settle on the final squad, which is tremendous credit to all who competed at the camp," he said.

"Now that we have settled on a team, I look forward to building together over the next month.

"We all know there is plenty to be done to achieve the result we all desire. We also know we have the people, chemistry and talent to attack the challenge ahead with confidence."

The Boomers will leave for Europe on August 5 for a nine-game pre-World Cup tour of Lithuania, including matches against fellow group rivals Finland and Ukraine.

They will take on Finland again in Helsinki, before travelling to Nice for clashes with France, Ukraine and the Philippines, and then a final two-game stop in Strasbourg.

Their World Cup campaign begins on August 31 (AEST) against Slovenia in the Canary Islands.
