The Prime Minister's XIII v Papua New Guinea match is shaping as a genuine selection trial ahead of the upcoming Four Nations tournament with a large number of incumbents and other hopefuls unavailable through injury.

In particular the prop and wing positions are wide open with Aaron Woods, Brenton Lawrence, Josh McGuire and Dylan Napa all in with a genuine chance of earning a Test debut up front and Daniel Tupou, Josh Mansour and Will Chambers in line for a place on the green and gold flanks.

Roos halfback Johnathan Thurston is also out due to shoulder surgery, meaning utility Daly Cherry-Evans is likely to move into the starting side, opening the way for any of Robbie Farah, Anthony Milford, Ben Hunt – or even Michael Morgan or Matt Mylan – to claim the bench utility role.

PM's XIII coach Laurie Daley has had to fly home due to a family illness meaning national coach Tim Sheens – who was in PNG to watch the game as a selector – is now managing the team directly. With Sheens taking a more hands-on role it means the hopefuls in the squad have a golden opportunity to stake a claim in front of the Kangaroos coach.

Raiders and PM's XIII forward Josh Papalii now looks almost a certain starter for the Four Nations but could be used to plug a gap in the front row rotation with the Australian back row stocks far less depleted.

Grand Final players weren't considered for the PM's XIII but the likes of Rabbitohs centre Dylan Walker and winger Alex Johnston and Bulldogs forwards Josh Jackson, David Klemmer and Aiden Tolman may also come into contention.

Among the incumbents unavailable from the Aussies' most recent match, the Trans Tasman Test in May, are fullback Billy Slater (shoulder), wingers Brett Morris (shoulder) and Darius Boyd (personal), halfback Johnathan Thurston (shoulder), props Matt Scott (shoulder), Nate Myles (bicep) and James Tamou (neck) and lock Paul Gallen (ASADA ban), and probably also centre Josh Morris (knee).

Other unavailable players with representative experience, or who are likely future representative players, include Andrew Fifita, Trent Merrin, Justin Hodges, Josh Dugan, Will Hopoate, and rugby-bound Maroons forward Ben Te'o.

Bulldogs and NSW halves Josh Reynolds (shoulder) and Trent Hodkinson (knee) and hooker Michael Ennis (foot) are also unlikely to be available.
