Australian jockeys continued to shine overseas with Craig Williams, Hugh Bowman and Tommy Berry riding winners in Japan and Hong Kong this week.

Williams snared the biggest win of the trio when he steered Esmeraldina home in the Group Two Kanto Oaks in Tokyo on Wednesday night.

It was the biggest victory of Williams' current stint in Japan where he has enjoyed Group One success previously.

In Hong Kong, Bowman continued his strong form on Wednesday when he celebrated his second winning double at Sha Tin in as many meetings.

Goldland Dancer gave Bowman a brace after he partnered Sledge Hammer to victory in the opening event on the card.

The Sydney jockey has ridden six winners at his past four meetings, taking him to eight winners since he joined the Hong Kong ranks at the end of April.

Berry joined the party aboard the Casper Fownes-trained Gun Pit to give the youngster 17 winners in Hong Kong this season.

Compatriot Zac Purton, who leads the Hong Kong Jockeys' Premiership by 18 winners with seven meetings remaining, failed to add to his tally at Sha Tin.

Purton's nearest rival Joao Moreira made up some ground on Purton with a victory on the John Size-trained Master Sommelier.

Meanwhile Sydney-based jockey Christian Reith has been granted a half-season contract in Hong Kong, starting mid-September.
