The Burnley teenager has no less than three England gloveman and an ex-Manchester United shot-stopper ahead of him at Turf Moor.
But the 18-year-old kid from Wollongong, who is on the cusp of Young Socceroos recognition, is up for the fight as he looks to duplicate the English top-tier feats of Mark Bosnich, Mark Schwwarzer and Mat Ryan.
The former Wollongong Wolves junior views competing with the England trio of Tom Heaton, Joe Hart, Nick Pope and Denmark international Anders Lindegaard as more a mission of attrition than mission impossible.
Having already picked up a smattering of Under-23 appearances along with a freshly signed one-year contract extension at Burnley’s academy, Calderbank-Park is playing the long game.
“You look at what Mark Schwarzer achieved in his career here in England and of course Mat Ryan at Brighton now, and you think why not me?” the ambitious youngster told The World Game.
“That’s the plan for sure. I feel that if they’ve achieved so much, and have been there and done it, then if I work hard enough I can follow suit. I’ve got to put the effort in and see what happens.”
Working with, and learning from a pedigree crop of keepers, is not something he takes lightly.
“It’s unbelievable talking and learning from keepers like Joe Hart and Nick Pope,” he said.
“I never thought in a million years I’d be in this position.
“The senior keepers are so professional and friendly and always make time to chat and help you.
“Sometimes when we train with them, they’re world class. Great to watch and look up to.
“The setup here is superb and it’s a great club to develop.
“For me it’s all a learning curve. Joe Hart and Tom Heaton are in their 30s and maybe getting towards the end of their careers.
“I’m just grateful to be in and around them, working hard and picking up as much knowledge as I can.
“You never know, once they crack on over the next few years and take another path, I can hopefully get an opportunity.”
Calderbank-Park was on the radar of Wales as recently as last month, before enquiries to Burnley by the Welsh FA revealed he did not meet the eligibility criteria after all.
Since then, Australia goalkeeping coach Tony Franken has been in touch with the family and Burnley’s academy chief John Pepper, and the youngster could be involved in an Under-20s camp in Canberra later this year.
“He’s doing well at Burnley and is definitely somebody we’re looking at,” Franken said.
“He’s been on our radar for a while now and we’ll continue to monitor him closely.
“He’s a promising young keeper who’s developing well at an EPL club where he’s learning from some top goalkeepers. We’re keen to have a look at him in a camp situation.”
Calderbank-Park, who left the ‘Gong in 2016 to chase his dream, won’t have to be asked twice, saying: “I’m buzzing about the possibility of that. I’ll grab that chance if it comes.”
On match days - when not involved with Burnley’s Under-23s - Calberbank-Park plays with Padiham in English football’s seventh tier to gain experience, with a possible loan to a club higher up the pecking order in the offing next season.
