Tom Trbojevic is attempting to find his voice under the tutelage of Billy Slater as he dreams of inheriting the coveted Australian No.1 jumper.
After making his Kangaroos debut in last week's Rugby League World Cup group win over France, Trbojevic will again get a chance to impress coach Mal Meninga against Lebanon on Saturday.
The 21-year-old was given a shot on the right wing against the French and will turn out in the unfamiliar position of centre against the Cedars at Allianz Stadium.
However he harbours a desire to wear the green and gold No.1.
Trbojevic has so far spent his first Australian camp trying to learn from Billy Slater, who he considers the greatest fullback of all time.
And the quietly spoken Manly young gun reckons his biggest take-away is that he needs to be a whole lot louder.
He says he's amazed at how vocal Slater is while organising his troops at the back and it's something he wants to incorporate into his game.
"He's been so good for so long and he probably is the best fullback to ever play the game," Trbojevic said.
"The thing ... is the way he talks at training, on the field. You never hear him shut up, he's that loud.
"Honestly, if you go down there and listen to him, he's so good at telling people what he wants and you need that from your good fullbacks."
With Slater rested, Valentine Holmes gets his chance at fullback against Lebanon a week out from the quarter-finals.
While the likes of Slater, Greg Inglis and Darius Boyd are still several years off retirement, their eventual departures will open a vacancy at the back for Australia.
One of Holmes, Trbojevic and James Tedesco - who missed out on Australian selection for the World Cup - is the long-term heir apparent and deciding who will give Meninga food for thought.
Trbojevic says he's happy to play anywhere knowing that Inglis, Boyd and Josh Dugan have been moved around in the backline at state and national level because of the abundance of class fullbacks.
"(Meninga) said that versatility is a big thing for him and I'm just happy to play where he wants me," he said.
