Philadephia 76ers star Ben Simmons headlines an NBA player-dominated preliminary Australia squad announced Thursday for this year's Basketball World Cup in China.

Nine US-based players form the core of the 17-man Boomers squad, including Andrew Bogut of NBA champions Golden State Warriors, Joe Ingles of the Utah Jazz, Patty Mills of the San Antonio Spurs and another 76er, Jonah Bolden.

The NBA has seen a record number of Australian players this year and the Boomers are being touted as the strongest from the country to play at a World Cup.

Simmons' 76ers lost the Eastern Conference semifinals after an incredible game seven buzzer-beater by the Toronto Raptor's Kawhi Leonard earlier this month.

The former NBA rookie of the year took to social media this week to let 76er fans know he was energised for next year after a "tough way to finish the season." "I would also like to announce that I am going to be a Boomer for the upcoming events. So stay tuned," Simmons added in a video posted to Twitter.

Sudanese-Australian Thon Maker was pulled from the Boomers squad at the last minute, reportedly at the request of his NBA team the Detroit Pistons.  

The final 12-man squad will be selected during team camp in August. They will take on Canada and the US in warm-up matches in Perth and Melbourne that month with their World Cup campaign beginning against the Canadians on September 1 in China.
