Captain Ase Boas is back after being given the green light, while fullback Stargroth Amean has been ruled out of the opener due to injury.
Forward John Andy will become Hunter #54 after being named in the starting side.
"Stargroth is still nursing a rib injury and also has a chest infection so Adex Wera comes in for him at fullback," said Assistant Coach, Nigel Hukula.
"John is a dynamic player and brings a lot of aggression to the game, earning him a call up."
On the return of Boas, Hukula said the star halfback is fit and will be back at his best.
He said Boas will be backed up by Charlie Simon.
Boas knows it won't be easy.
"It will be another tough year as we are the defending champions.
"It's going to come with a lot of hard work."
An excited Andy said he was looking forward to his debut in front of a home crowd.
"It's a dream-come-true for me."
This Sunday's match kicks off at 3pm at the Oil Search National Football Stadium.
