Ben Simmons has been included on Australia's extended basketball squad for this summer's Olympics. 

Boomers coach Andrej Lemanis on Monday named 26 players, including Simmons, seven NBA players and 13 from the NBL, ahead of the team's one and only pre-Games camp in July.

The squad will be cut to 16 for the selection camp from July 5-10, once the Boomers' commitments in the NBA and Europe finish.

"The time frame dictates that we can only have one camp but it is the way it has been for years so it's not unusual," added Lemanis.

"It's a case of the selection staff taking into account previous history with the Boomers, current form, injuries team balance and chemistry and putting all that together."
