Steve is near the Blue Mountains in Kurrajong Heights, NSW. Approx 45 minutes to an hour from Parramatta according to his website. I think to drive down it takes about 16 hours? AFAIK Steve can cater from people coming from other states and can organise accomodation for you, I'd email him and have a chat
16 hours , that would be one hell of a trip if he looked at my boy and said he couldn't help
