The 2025 Pacific Championships is heating up, and this week’s round two action promises a blockbuster showdown with Papua New Guinea’s (PNG) Kumuls set to unveil a supercharged lineup headlined by the return of five key stars, including skipper Lachlan Lam and tryscoring weapon Alex Johnston.

After fielding an experimental side in the Prime Minister's XIII clash a week ago, which the Australians won 28-10, the Kumuls have reloaded with experience, flair and firepower in every position - a clear signal they’re here to contend.

With Lam pulling the strings at halfback and electric hooker Edwin Ipape injecting speed around the ruck, PNG look primed to unleash their trademark aggressive style.

But it's not just about who's back, it's who’s stepping up.

Morea Morea, who only made his debut last November off the bench, has earned the No.1 jersey in a bold call by coach Justin Holbrook.

His elevation has allowed Nene Macdonald, a veteran of 20 Tests, to shift to centre in a move that adds both stability and strike power.

Joining them are ironman Rhyse Martin in the back row and silky centre Zac Laybutt, giving the backline a dangerous mix of size and skill.

Up front, enforcers Jack de Belin and Nixon Putt anchor a forward pack built to dominate collisions, while young gun Cooper Bai, son of PNG legend Marcus Bai, is set for an emotional Test debut from the bench.

PNG’s opponents this week, the Cook Islands Aitu, will need to be ready for a side that suddenly looks like a serious title threat.

Around the grounds

Elsewhere in the Pacific Championships, Tonga XIII are boasting a near Test-strength lineup, led by powerhouses Addin Fonua-Blake and Jason Taumalolo.

With State of Origin centre Robert Toia and NRL regulars Stefano Utoikamanu and Isaiya Katoa among their ranks, Tonga are in win-now mode - though missing Sea Eagles stars Haumole Olakau'atu and Taniela Paseka could leave a dent in their go-forward.

Toa Sāmoa are battling injuries, with Jazz Tevaga named despite a head knock last week, and prop Terrell May in a race against time. But the inclusion of Super League champion Tyrone May adds steel and smarts, while exciting Dragons prospect Lyhkan King-Togia waits in the wings as 18th man.

In the women’s competition, all eyes will be on the Jillaroos as they launch their campaign with three fresh faces, including Jesse Southwell, who replaces injured playmaker Tarryn Aiken.

Australia’s depth remains unmatched, but Tonga and Fetu Sāmoa both bring rising talent and aggressive intent, with Moana and Tonga XIII naming a combined total of 12 Test debutants between them.

With finals fast approaching and pride on the line, this week feels like the calm before the storm.

For PNG, it’s a week of resurgence. With Lam at the helm and Johnston out wide, the Kumuls have the look of a team that not only believes they belong, but intends to take the trophy home.
