Tim Clark has been back from Hong Kong for more than a year and is starting to get back to the top of the Sydney riding ranks, but it has not been easy.

Hong Kong is considered the most competitive riding theatre in the world but Clark believes Sydney is just as tough.

‘‘There is such depth here and you need to be at the top of your game,’’ Clark said. ‘‘I rode well when I came back and then went through a bit of form slump, but this year I have very happy with my form and the winners have started to flow.’’

He has not been forgotten by Hong Kong and ventured back there last weekend for a day of riding, but Australia is home and it is where he wants to make his mark.

‘‘I just want to stay here for a while,’’ Clark said. ‘‘I had that experience over there and it was good. If was to return [to Asia] I would rather do it on a short-term contract, but I want to get back to riding group 1 winners here.’’

Clark is always on the outlook for the next emerging horse. He has linked with Les Bridge, with who he shared Hot Danish’s group 1 successes, and Avoid Lightning in more recent times.

‘‘Les has always stuck solid and I think we are both looking for another Hot Danish,’’ Clark said. ‘‘She was the sort of horse that gets you noticed. It helps get other rides because people want the bloke who is in form.’’

Avoid Lightning is a quality sprinting mare, which won the Birthday Card Quality and was runner-up to Cosmic Endeavour in the Sapphire Stakes during the carnival before winning an open 1100 at Randwick last time. She has been given the 59-kilogram top weight for the June Stakes but Clark is confident she will have the measure of her rivals on a wet track again.

‘‘She has been going terrific," he said. "She gave weight to all her rivals last time and gave them a beating. She will handle the big weight and they will have to be pretty good to beat her. She loves the wet and she is getting better with every run.’’

Clark has been in demand and is booked for rides by Bart and James Cummings, Chris Waller and Paul Messara on Saturday.

He teams with debutant Coolcraft to open the Randwick program after riding him in a couple of barrier trials. ‘‘He has got some confidence out his trials and Saturday's race looks a good place for him to start because I think it is a very winnable race,’’ Clark said.

Later in the day he rides the Waller-trained Specific Choice, which has proven a frustration for punters, but Clark is expecting him to improve from his first-up run, where he finished midfield. ‘‘They went so slow in that race he was never a hope,’’ Clark said. ‘‘I'd be giving him another chance because he is talented.’’
