Deborah Tsai (20), Danielle Kettlewell (22), Danielle ten Vaanholt (21), Rose Stackpole (19) and Amie Thompson (19) have been training at HBF Stadium and the new WA Institute of Sport High Performance Centre for the past two weeks.
National assistant coach Julianna Ghazali Bujang is also based in Perth.
The 10-player team that will represent Australia at the World Championships in Russia from July 22 will be selected at the Australian Institute of Sport in Canberra this week.
Tsai said being selected for her first World Championships was one of her main goals.
She said everyone had their different strengths so it was hard to predict who would win selection but being able to train with four other West Australian squad members was an advantage.
�It�s been really good over the past year being able to train together here,� Tsai said.
The Claremont-based West Coast Splash club member is vying for an �acrobat� place in the team.
The World Championships will be held in Kazan and Australia has to beat New Zealand to qualify for the 2016 Olympics.
Australia has beaten NZ in the past few matches but Tsai said NZ had a few new and younger players so would be tough opposition.
