Fresh from signing with French side Basket Landes, the four-time WNBL championship winner will feature in a star-studded squad captained by Jenna O'Hea, and featuring four debutants as well as WNBA stars Liz Cambage and Eziyoda Magbegor.

Tolo was thrilled about getting her chance to compete for the Opals again and help her side back in to medal contention.

"It's what every kid dreams of, especially the way the Olympics went for us last time," Tolo said.

"We lost in the quarter-finals and didn't get the chance to play off for a medal, that was really heartbreaking. It would be a chance at redemption for me."

The Opals have a history of success at Olympic level having won five medals since Atlanta in 1996 and will be looking to bounce back from the team's disappointing result in Rio in 2016 where they fell in the quarter finals to eventual Bronze medalists Serbia.

The Australian Olympic Committee announced their squad with Head Coach Sandy Brondello at the helm for what will be her first Olympics as a coach.

She took on the role in 2017, having competed in four Olympics as a player.

Brondello was optimistic about the Opals' chances of success at the delayed Tokyo Olympics.

"We know it's hard to win an Olympic medal but I do believe this team puts us in the best position to do that and we'll be working extremely hard to make sure we achieve that goal," Brondello said.

"I think we are capable of that gold medal."

The Opals are ranked number two in the world and have been drawn in Group C and will go head to head with Belgium, Puerto Rico and China in the group stage of the competition when it tips off on July 27th.

Cambage, who took part in London 2012 and Rio 2016, is the most experienced member of Brondello's squad.

The imposing centre and Rebecca Allen will link with the national side for the first time in 16 months at a pre-Games camp in Las Vegas, which will serve as the Opals' final match practice before flying to Japan.

Cambage, who was born in London to an Australian mother and a Nigerian father, has been a vocal advocate regarding racism, discrimination and other issues.

There had been speculation as to whether the 29-year-old would compete in Tokyo after publicly condemning a photo shoot of Australian Olympians as being "whitewashed", asking how was she meant to represent a country that doesn't represent her.

Chef de Mission Ian Chesterman is yet to speak with Cambage but conceded "she made a valid point".

"It's important that athletes feel free to speak about issues close to their heart. We fully support that," Chesterman told AAP.

"It's not something we, as an Olympic movement, want to silence."

Cambage recently found herself in the headlines, having been subjected to a remark about her weight during an WNBA match that led to a fine and suspension for Connecticut Sun coach Curt Miller.
