World Rugby has confirmed the Wallaroos will join USA, Canada and New Zealand as part of the inaugural Pacific Four Series.
The USA and Canada will kick off the tournament later in the year in the form of a soft launch, with the four-team format set to formally debut in 2022.
The tournament will serve as major preparation ahead of next year's World Cup, along with acting as one of the main annual qualifying routes for the top tier of the WXV tournament, which was announced at the start of the year.
World Rugby Chairman Sir Bill Beaumont said in a statement: “World Rugby is committed to investing into high-performance competitions to increase the competitiveness of the women’s game at elite level.
“We had previously announced a new cross-regional tournament featuring New Zealand, Australia, USA and Canada as part of the WXV competition qualification structure, which starts in 2023.
“The Pacific Four Series will provide quality playing opportunities and further support teams as they prepare to compete at Rugby World Cup 2021 in New Zealand next year.
“We look forward to watching teams compete again at the highest level for what will undoubtedly be a thrilling showcase of women's elite rugby from some of the best teams in the world."
