Christian Tsangas was born with cerebral palsy.
The condition affects his agility, how he walks and - crucially - his sideways movements.
Given the challenges, goal-keeping wasn't a natural fit.
But the 19 year-old has overcome his challenges to guard the net for Australia with the Pararoos.
He says it was worth every drop of sweat it took to get there.
"It's played a massive part in my development as a person, it's given me a greater amount of confidence around my family and friends. I don't know where I'd be without my football to be honest, it's been a massive part of my life."
Tsangas debuted in the Pararoos seniors' squad last month in Denmark, helping Australia qualify for the 2017 World Championships in the seven-a-side football competition.
He says running out on the pitch for Australia has been his biggest achievement.
"It's a special feeling - nothing beats it, that'd why we play football. It's the goal every player wants to achieve, to represent your country it's the highest of honours."
But it's an honour Australian players are in danger of losing.
Federal funding for the Pararoos was scrapped two years ago, leaving the Pararoos to rely on donations to get to the World Championships next year and the 2019 World Cup - both of which they've already qualified for.
But Tsangas says they're no strangers to overcoming obstacles.
"Everyone has their limits at the end of the day, but you can go as far as you want to go - it just depends on how hard you want to work and how much you'll put in to get there."
And - like the rest of his team - he's put in a lot.
As the best-ranked side in Oceania, the Pararoos have a real chance at an international title if they can find the funds to continue the journey.
"It's been a hell of a ride, so hopefully it can continue."
