Both Australians finished tied for the lead after three rounds, before playoffs determined the world champions.

Representing Australia, the two young golfers delivered outstanding performances against the world's best junior players, each finishing runner-up in their respective divisions.

Seven-year-old Will Veitch, a member of The National Golf Club, produced one of the standout performances of the tournament in the Boys 7 division, carding rounds of 35, 35 and 36 to finish 2-under par, tied for the lead after 27 holes.

Will then contested a remarkable four-hole playoff before ultimately claiming the World Championship silver medal. He was one of only two players in his division to finish under par across the championship.

In the Girls 7 and Under division, Angelika Britto, a member of Sanctuary Lakes Golf Club, was equally impressive, recording rounds of 32, 36 and 33 to finish 7-under par, tying the eventual champion after regulation before also claiming the World Championship silver medal following a playoff.

Together, the pair delivered one of Australia's strongest performances at the prestigious international event, which attracts thousands of the world's best junior golfers each year.

Both children were caddied throughout the championship by their parents, with Will accompanied by his father, Nick Veitch, and Angelika by her mother, Jessie Xu.

Their performances reflected not only exceptional golfing ability, but also remarkable composure, resilience and sportsmanship under intense pressure, with both children maintaining their positions at the top of the leaderboard throughout the tournament before being separated only by playoffs.

The US Kids Golf World Championship is regarded as one of the world's premier junior golf tournaments, attracting the best young players from across the globe. With both children returning to Melbourne as world silver medallists, their performances highlight the strength of Australian junior golf and the exciting talent emerging through the state's junior ranks.
