Despite dominating the Opals' warm-up series sweep over Japan, Australian basketball star Liz Cambage's best is still to come, according to coach Brendan Joyce.
Cambage top-scored in each of the women's team's three games, including a 26-point haul in Tuesday night's 84-73 win in Tokyo.
She shot 10-14 from the field and had seven rebounds, three steals and as many blocks.
It was the centre's first competitive hit-out with the Opals since rupturing her anterior cruciate ligament in 2014.
"Everyone was waiting to see how Liz would fit back in and she's fitted straight back in," Joyce told AAP.
"We made her a focal point because obviously her size is a big factor against a team like Japan because they're not tall, and she was able to deliver."
Joyce said Cambage would give Australia an edge they lacked at the world championships in Turkey at the Olympic Games in Rio - especially against the world No.1 USA.
"She's going to create problems for anybody we play," he added.
"And she's not at her best yet. We had her firing on all cylinders before worlds; her fitness levels were superior to what they are now (before her ACL injury).
"That's what we're working towards on these tours and I think her best is going to come when the timing is right in late July-August."
Joyce was pleased with his side's speed against their world No.16 rivals, who have been drawn in the same group for Rio, and the consistent defensive efforts of Steph Talbot and Nat Burton.
Tuesday's 11-point win was the tightest of the Opals' tour, having won game one 80-41 and their second 81-55.
The team next head to Europe for a two-week tour starting later this month, before returning to Australia for two final camps in June and July.
Joyce expects injured centre Marianna Tolo to join the team in Europe, as well as France-based star Laura Hodges, but doubt remains over Tess Madgen (ankle) and Sara Blicavs (foot).
"There's a number of spots there still open and the European tour is going to sort a lot out," adds Joyce, who is yet to name his final team of 12.
The Opals are chasing their first Olympic gold medal in Rio, having won silver or bronze at every Games since 1996 in Atlanta.
