The men's and women's Olympic sevens champions will take to the field today for the time since their Rio success.
Osea Kolinisau is one of three gold medallists in the Fiji men's line-up contesting the Oceania Sevens Championship in Suva, alongside Jasa Veremalua and Samisoni Viriviri.
Seven debutantes are also in the Fiji squad, which will be coached by Naca Cawanibuka until January, following the departure of Ben Ryan.
The Australian women's team were equally dominant last season, adding Olympic gold to their maiden World Series crown.
Head coach Tim Walsh said they're looking forward getting back into it.
"We love coming to Fiji and also playing the Oceania competition, and it's just the perfect way to prepare yourself for a World Series," Walsh said.
"It's hard and fast and entertaining and it gets the team back touring again so to get out there and play, leading into a World Series and having that label of the Olympic medallists as well, all the other teams are out to get you."
Walsh said the true reflection of any champion team is how they go in their second year and if they can show that character that got them there in the first place to back it up.
The seven women's teams will play each other once during the round robin phase.
Australia's opening match is against Solomon Islands, while the Fijiana open the tournament against Papua New Guinea.
The 10 men's teams have been split into two groups, with Fiji's first match against American Samoa in Pool A.
Fellow World Series regulars Samoa and Australia are both in Pool B.
