Having spent most of his life in the more claustrophobic environs of Hong Kong, Gus came down to New Zealand to learn about life on the farm and as Williams describes it "get his hands dirty".
"He had barely touched a horse in his life before he got here but he is loving learning all about them."
But Gus didn't come empty-handed, he brought with him a skill, the ability to speak Mandarin Chinese and Williams saw an opportunity.
"With the way the sales are this year, with no overseas buyers able to get into the country, we have really tried to up our info game," he says.
"So we have an e-book detailing everything a buyer could need to know about the horses but we are also lucky enough to have Gus here to do voiceovers for our yearling videos in Mandarin.
"So people can now go online and watch the horses parade but not just with our usual English information but separate videos in Mandarin.
"We are starting to get some really good feedback on it, now that potential buyers are starting to do more research and it is just another service we are trying to provide.
"I think a lot of vendors are working really hard to meet the market demands under the trying circumstances so for us to have Gus available to take it that one step further is great."
Little Avondale Stud is in its 80th year, itself no mean feat, and stand one of New Zealand's leading value for money stallions in Per Incanto.
He had another Group 1 winner in Bonham at Trentham last Saturday and is hugely popular in that key Hong Kong market.
"When you consider what he stands for and what his yearlings sell for and then go on and do on the track he is a wonderful stallion," says Williams.
"He has had 20 individual winners across the world in the last 20 days," Williams adds.
Little Avondale also bring the first yearling by their new stallion Time Test, a Royal Ascot track record holder by champion European stallion Dubawi, to Karaka this week.
"To already have Per Incanto and now be able to bring the Time Test yearlings to the sales, we feel pretty lucky."
Little Avondale also bred Avonallo, one of the key chances in Saturday's Karaka Million.
