Sorry guys, been away for a few days. Werribee strip is at the north west edge of Werribee (just off the road to Bacchus Marsh), about 3nm NW of the racecourse and about 5nm NW of the Mansion/Equestrian Centre. It's marked on the Melbourne VTC.
Noel's home number is 03 9742 4227 (it's noted on a few websites, white pages so don't think disclosing it here is infringing). As mentioned, Noel and his wife Fay are lovely people and very welcoming.
