I don't know a whole lot about the salvage market here, but there are a few places which specialise in stripping old yachts and selling parts through their chandleries. I guess it depends if your friend is buying or selling. Yachts in Austalia are relatively expensive, especially second hand. To gauge the approximate state of the second hand market in Oz, go to boatpoint.com.au. It is the largest used boat collection in the country.
You will be amazed by just how much you will have to pay for a 15 to 20 year old Beneteau in fair condition.
