Australia can secure passage to Tokyo 2020 at the Oceania Sevens by winning their section of the tournament, where Tonga and Samoa shape as their two biggest hurdles.
A strong Australian squad will play Vanuatu and Nauru on Thursday before games against American Samoa and Tonga on Friday and if they both top their pool, a likely Olympic play-off against Samoa on Saturday.
The already-qualified New Zealand and Fiji will also play in Suva, but not against Australia until the Olympic quota spot has been decided.
