Spirit coach Kevin Foote has named the 33 men charged with defending their NRC title.
Foote's squad features 15 players who helped lift the trophy last season, along with 11 players from Pindan Premier Grade.
“I think it is probably the strongest squad we have named,” Foote said.
“We had a strong squad last year but this year having so many contracted players come through plus the coaching staff is very positive for the competition and Western Australia.“I think the guys want to come out and go back-to-back, that is the goal and the group is very focused.
"We are going to be looking to throw the ball around and play some really attractive Western Australian rugby."
Foote spoke of his love of the NRC and the pride he takes in picking players from the local club competition.
“We have some really talented guys from the Pindan Premier Grade in the squad, those guys play for the love of the game, they play with great spirit and great heart, I think they will add a lot of value to the ‘Piggies’," Foote said.
“I love the NRC, I love seeing everyone the kids and the families come down to ‘Fill the Hill’ and watch the Spirit.
"We love playing at McGillivray Oval and running out in the black and gold jersey, everyone takes a lot of pride in wearing the state colours.”
Adam Coleman, Dane Haylett-Petty, Richard Hardwick and Tatafu Polota-Nau are the Wallabies listed among the squad, though they may only get service out of Hardwick, given the other three are fixtures in the Wallabies 23.
