One Melbourne Cup will be enough for Green Moon but four aren't sufficient for his owner.

"There's a lot more Melbourne Cups to come," said Lloyd Williams, the man who found Green Moon in England and brought him to Australia.

"It's a bit late in life for me to stop now ... it's a disease."

Williams, however, didn't indulge his passion to the extent of going to Flemington to see his horse run.

He admitted on Wednesday to watching the Cup from his training complex at Mt Macedon north of Melbourne "with the sound turned down", and to celebrating with a cup of tea.

Green Moon, who spent much of the day after his momentous win munching on grass fed to him from the $175,000 solid gold trophy he won on Tuesday, will be aimed at more conservative targets in the future.

"He will probably go down a different path next year," his owner said.

Whatever that path may be, it won't involve racing overseas nor will Green Moon go to stud.

"We're pretty happy here at home," Williams said.

"I'm fiercely Australian, fiercely Melburnian.

"And no one is asking me to send him to stud just yet. I like racing them."

Williams has spent several fortunes on his passion, collecting his first Cup in 1981 with Just A Dash, his second with What A Nuisance in 1985 and a third in 2007 with Efficient.

But Green Moon is the only one of his quartet of Melbourne Cup winners capable of fathering a winner of Australia's greatest race.

As he recovered from his Cup exertions, even that aspect of his future seemed too distant to contemplate.

Green Moon spent much of the day posing for the cameras and eating, watched by his proud owners and his recently retired predecessor Efficient who looked on from his stall.

Approvingly, you would have to think.
