"I'm pretty stoked that he's (coach Stephen Kearney) given me the opportunity this season.
"I feel I've put my best foot forward in all of the games I've been able to play.
"Hopefully next year I can build and get a few more games and go from there.
"That's the goal. I feel like I can definitely make a big step forward going into next year - after winning the finals with ISP."
Papali'i admits it's been a big learning curve, having played in the Under 20s NYC competition last season before being thrust into the NRL for the round one home match against the Knights.
Having been given a taste of the big time, he was then put back to reserve grade and made to wait, before injuries saw him called on again for the round 22 rematch in Newcastle.
The time spent in the second tier competition has been beneficial, he says, in conditioning his body and mind to handle the rigours of NRL.
"I've just been learning whenever I got the opportunity and even in ISP, because it's my first year there," he said.
"I definitely found improvement from it and it really helps me when I play NRL, just the physicality of playing against men that are a lot bigger and stronger than me."
Papali'i looked right at home in 12 appearances for the reserve grade side, who finished second in the regular season, although they'll again be without him in Sunday's week one playoff against Penrith at UOW Jubilee Oval (6pm kick-off NZT).
"We've got a strong group of boys heading into the finals which is definitely good for us as a club as well as a team.
"I'm looking forward to playing a part in that finals series after this weekend."
