Jockey Craig Williams travelled with success at the weekend, and there is more travel to come for the in-form Victorian hoop.

The four-time Scobie Breasley Medal winner earned his 36th Group 1 win in Australia when steering the Chris Waller-trained Good Project to victory in the $1million Railway Stakes (1600m) at Ascot in Perth.

And Williams, fourth in the Victorian Metro Jockey Premiership with 17 wins, will continue his travels up until Christmas, with the highlight of those being a venture to Sha Tin to partner Criterion in the Hong Kong Cup (2000m) on December 13.

"I'm looking forward to it. David's very happy with his preparation," Williams told Racing.com'sRacing Ahead on RSN.

"When you look at the field this year, it's not as strong as previous Cups.

"Most importantly, we've seen Criterion compete in Hong Kong - he likes getting over there. He's had a rock solid preparation over the last 18 months.

"I'm looking forward to representing Australia."

And either side of teaming up with Lindsay Park at the international event, Williams will also be flying the Victorian flag for the Origin Jockeys' Series - a four-week competition created by Racing Queensland, held over three meetings at Doomben and one at the Gold Coast.

Williams and Dwayne Dunn are among the Victorian representatives, while Glen Boss will don Queensland colours, Tye Angland steps out for New South Wales while Opie Bosson and Damian Browne ride for New Zealand.

"Really looking forward to be able to promote Victoria and this concept," Williams said.

"It worked out well that we didn't have to do all four Saturdays in a row.

"Because they were flexible with availability, I was very keen.

"Glen Boss, Damian Browne, Dwayne Dunn are involved.

"Bossy was chatting to Alfie Langer the other day, so there's no doubt he was getting some advice off him about State of Origin."

On his all-the-way win aboard Good Project, Williams said the four-year-old entire was always going to measure up well despite being his first start at Group 1 level.

"When you go through the history of the race, he fit the profile really well," two-time Railway winner Williams said.

"He'd been targeted for the race, the horse was in form, and even though he was racing in lesser company in the eastern states, the times he was running with really big weights, it showed you he could have that great acceleration.

"Also that he's very versatile in his running style that proved to be a big advantage on Saturday."
