His father said because he had been busy at the motel in Mudgee - a recent acquisition - his son had not been at Flemington to see the St Leger win but had watched Cool Chap's success on television.
Mr Wilton is a part-owner of the horse and has shared in the ownership of other horses in the past, including Frisco Agogo and Frisco Lass, the latter having won on debut paying A$72 ($79) on the win machine.
Cool Chap is trained by Lee Freedman, having earlier been prepared by Peter Moody, who gave away training only a month or so ago.
The galloper has now won three times in just seven starts and has chalked up two seconds and a third.
His prize money in his short career so far totals A$213,250.
Mr Wilton is married to Jennifer and the couple have two children.
He is likely to be remembered in Wairarapa for his skill as a hockey player.
