Hi Sheap
You can obtain to GSO 8" Dob from Andrews Comms in Sydney (Greystanes) via mail order. I had my 12" dob shipped to my home in Townsville - a little further from Syadney than you would be in Melbourne - for around $90; bargain. It arrived 3 days later, at my door, in perfect order. No trouble.
Andrews has the 8" standard version for $399, or the deluxe version for $449. This version has a 2" Crayford style focusser which will allow you to use 1.25" and 2" eyepieces. This is a superior focusser to the r&p type
Good luck
Dave
PS; you won't be dissapointed with a Dobsonian 'scope.
