The Castleford Tigers hooker has recently secured a £185,000 transfer to Warrington Wolves on a four-year deal.
The Steve Prescott Man of Steel winner is expected to take his game to another level with the Super League high-fliers but will still only be 25 when that contract expires.
Hull KR hooker Josh Hodgson – who joins Clark in the England squad heading out to the Four Nations next week – has already earned a deal with Canberra Raiders.
Many of the top players here are now making the move and Clark said: “I am a massive fan of the NRL. And, one day, I would like to go there and test myself.
“I want to establish myself in Super League first.
“I’ve already been made aware I’ll have pretty big boots to fill at Warrington after Michael Monaghan’s retirement.
“He’s been outstanding for the four, five years he’s been there but I’m going in quite confident.
“I’ll get my head down, work hard and hopefully carry on from where I left off at Cas and playing well.
“Then, in a few years time, I would like to try the NRL.”
Clark, 21, is sure he and fellow uncapped nine Hodgson can handle the pressure of taking control for England on the biggest stage.
National coach Steve McNamara is without first-choice hooker James Roby and Wigan’s experienced Michael McIlorum for the tour due to injuries although there is nothing to say he would still not have taken the impressive in-form rookie duo.
“Josh has had a great season with Hull KR and he’s been rewarded by signing with Canberra,” said Clark.
“It is going to be tough but we’re both confident we can fit in and do a job. I am and I’m pretty sure Josh will be as well.”
