All the talk's been about the halves, but it's not just in the playmaking roles that Australia coach Mal Meninga faces a selection headache.
It's also in the centres after Canberra Raiders star Jack Wighton scored two tries and set-up two more in the Kangaroos' 15-try romp over Scotland on Saturday.
He'll have to be in Meninga's thoughts come the business end of the tournament, from a pool that also included Latrell Mitchell, Valentine Holmes and Matt Burton.
Meninga will also need to decide whether he sticks with having both a back-up hooker and a utility on his bench come semi-final time.
