In the 2013/14 season, Purton ended the 13-year championship reign of
Douglas Whyte, becoming the first Australian jockey to win the Hong Kong title since Noel Barker in 1991. (112 wins). He notched up 112 wins on his way to the title. Purton also raced to what was then the fastest 50 in Hong Kong history that season and became the second rider, after Whyte, to notch 100 wins in a season. Purton lost his title when he came second to
João Moreira in 2014/15 with 95 wins, then was runner-up to Moreira again in 2015-16 and 2016–17 before reclaiming the Hong Kong championship in 2017–18 in a close finish. Purton's record-setting 179 wins in the 2023–24 season delivered a sixth Hong Kong jockeys’ championship, but that was achieved with his arch-rivals Whyte and Moreira out of the picture. First there was the 2021-22 title which he took after a season-long duel with Joao Moreira. Purton rode four winners to Moreira's none on the final day of the season to clinch his fifth title. Whyte has the most wins all-time by a jockey in Hong Kong. Purton took the record with his 1,814th win, View Of The World at
Happy Valley on January 22, 2025. Purton represented Hong Kong in the
World Super Jockey Series held by the
Japan Racing Association in 2012, recording two wins and being crowned as champion. He won the Hong Kong Derby in 2015, with the John Size-trained Luger, and his Hong Kong Cup win on Time Warp in 2017 made Purton only the third jockey, after
Gerald Mosse and Moreira, to have won all four of Hong Kong's December international races. In the 2024/25 season, Purton won eight races from eight starts on sprinter Ka Ying Rising, including four Group 1 races. Ka Ying Rising first broke Sha Tin's 1200m track record in November 2024 when he ran 1:07.43 in the G2 Jockey Club Sprint – shading former champion Sacred Kingdom's 17-year-old record – before setting a new mark of 1:07.20 in the G1 Centenary Sprint Cup in January 2025. ==Major wins ==
