The former Wigan utility back, who operates mainly at centre, but can also play fullback, wants to improve his skill levels, but also get physically bigger, during his time Down Under.
“I want to put on a bit of size, and maintain the fitness I had,” he told Australian reporters.
“There’s a lot of big boys here! I need to do that, but, obviously, coming over here, I’ll work a lot on my skill.
“Hopefully I can adapt to that, and put on some size, and that will hopefully stand me in good stead for the season.
“Careerwise, it’s the best decision I could have made – coming to a club like this.
“The only thing that was half-stopping me was my family, but once I’d got over that, and a few tears at the airport, I’m alright and I’m ready to rip in.”
“It’s a much higher level of competition. It can only improve you as a player.
“Hopefully I can follow in their footsteps and develop as a player.”
Sarginson is also ready to fight for a first-team berth, in whatever position in which he is selected.
“As long as I’m on the field, I’m happy,” he said.
“I’ll fight to play in the centres, and if I’m needed at fullback then that’s definitely an option.
“I wouldn’t turn it down.”
