HINCHINBROOK'S Joseph Mawson won the final round of the CIK-FIA under-18 world karting championships in Bahrain on Saturday night.
He beat Monaco driver Charles Leclerc and Britain's Ben Barnicoat.
The win was the first by an Australian in a world championships event since 2010 V8 Supercar champion James Courtney won his second world karting title in 1997.
"When I crossed the line for the win, I was just overwhelmed with emotion. It is the first time ever that I've cried in my helmet,"16-year-old Mawson said.
"I would have been happy with a podium finish to round the year off but to come away with a win is just amazing - not only for me but also for Australian karting."
Mawson said the race was one of the toughest he'd contested.
It was also the biggest win of his career.
"It was definitely a hard race, the track layout was extremely tough and made it hard to get a break," he said.
"I just put my head down and did the best that I could and on the last lap I had to block, which made it pretty interesting but in the end I got the win and to cross the line first in a world championship event is just unreal."
