The Wallaroos squad features two potential debutants, with fellow Sevens star Mahalia Murphy joined by Western Australian fly-half Trilleen Pomare. 

The squad features 156 caps of Test experience with nine having tasted Rugby World Cup action before, as the Wallaroos aim to build on their seventh place finish at the 2014 edition.

"We have had some solid preparation during our Test series in New Zealand earlier this month, and had the opportunity to blood some new talent at Test level,” Wallaroos coach Paul Verrell said.

"That tour in New Zealand really showed us the standard of the best three teams in the world and we know what we need to do to reach that level now, so it's time for the next generation of Wallaroos to really step up.

"We have a really competitive pool with Ireland, France and Japan and we know that there's no such thing as an easy game at a World Cup.

“We're really looking forward to pulling on that gold jersey and doing it proud," Verrell said.

Forward Mollie Gray returns to the Wallaroos fold, after injury ruled her out of the tour of New Zealand while young guns Kayla Sauvo and Millie Boyle have earned their trip to Ireland following a stand-out series.

Star back Ashleigh Hewson, who will be attending her third World Cup, needs just two more points to become the highest-points scorer in Wallaroos history to surpass the tally of former flyer Tricia Brown who scored 65 points.

The squad will convene in Sydney at the end of July for a three-day camp, ahead of flying out for Ireland on August 1.

The Wallaroos are in Pool C alongside hosts Ireland, as well as France and Japan.
