The Fiji 7s teams will be playing New Zealand and Australia twice during the Oceania 7s later this month.
The national sides will also play the Oceania Men’s and Women’s 7s teams twice and the highest ranked team after six matches will be declared champion.
The three-day tournament will mirror the Olympic format.
It will be the first time the men's teams from Australia, New Zealand and Fiji team have played in the same tournament since the Vancouver Sevens in March 2020, with the women last playing together in Sydney, a month earlier.
Australia and New Zealand played a six-match series in Auckland in May, but Fiji have not played an international match since early 2020.
This will be the last official hit-out for the three national teams before the Tokyo Olympic Tournament, which begins July 26, and will ensure teams the best possible preparation for the Games.
All matches will be played at Townsville’s Queensland Country Bank Stadium from June 25-27.
