Breen is part of a 35-strong squad that will be narrowed down to 30 by coach Scott Bemand before the trip to Canada and the 25-year-old believes she is in the best condition to stake a claim to be on the plane to Vancouver.
“I had a good pre-season, was worked hard and played the Interpros, so I felt that I have built nicely towards this campaign and can put my best foot forward.”
There are 10 uncapped players in the squad, as well as five sevens players who have returned from the Olympics in Paris.
As a result, Breen explained that Ireland’s focus before the Australia game has largely been on developing their own patterns of play.
“We’ve had a few new faces, which is normal at the start of a new campaign, so there are opportunities for everyone and the first few days have just been about building a connection,” she said.
“Australia are a team that likes to play, so do we, but we’re focusing on us and what we want to do.
“Whatever Australia throw at us we will have our own gameplan. We need to take our opportunities and use our attack as a weapon, as we use our defence as a weapon.”
