Hi Dave, I am in perth also so I went to see Keith in Malaga, unfortunately he didn't have the scope I wanted, I also rang Midland camera house but there prices are way over the top !, I have ordered from Astronomy Alive (they have an advert here) and they have a little info on the web site about warranty , take a look here
http://www.astronomyalive.com.au/about-us you will have to scroll down a little to read it, then you can ask Keith if he does the same warranty

Actually you will have to scroll down quite a bit, there is also some info on grey imports
