Charlie Camus was only six years old when he decided he wanted to be a professional tennis player.
He was sitting in the stands with his father at the Australian Open at the time, watching some of the world's top players on the court.
"When I was watching all those pros play, I just thought 'that's what I want to be when I grow up,'" he said.
Now 15, he is the youngest player preparing to compete at this year's Australian Open Junior Championships after earning a wildcard spot.
Charlie is currently ranked number one in Australia for his age and 5th in the under 18s category.
He also holds a junior world ranking of 232 after winning four titles in International Tennis Federation (ITF) tournaments in Europe in October and November.
"It was a trip of a lifetime," he said of his European tour.
"Not many 15-year-old kids get to go to Europe for two months.
"I speak French which helped, and we got to do a few tourist things as well."
Tennis ACT CEO Kim Kachel said Charlie's resilience on the court was "impressive to see".
"He hit the ground and won his first event straight up and turned 15 during that event."
Training with Nick Kyrgios 'priceless'
To top off his recent success, Charlie spent December training in Canberra alongside one of his idols and his mentor, Nick Kyrgios.
"There are thousands of people in the world who would wish to have that opportunity and you can't take it for granted.
"He gives me priceless advice to help my game and life on tour."
Reaching the men's top 100 like Kyrgios is a dream for Charlie, who first picked up a racquet when he was just three years old.
And he is well on the way there, with a current win-rate of 87 per cent.
Mr Kachel said Charlie had what it took to become an elite player, spending hours on court each day and in the gym.
"That fire inside of him has been burning for quite a while and he's been a very promising junior all the way through from 10 [years of age].
"He's got a great family and a great support network behind him … and I have high hope he'll keep progressing the way he is."
