I'm sure there are Hobie dealers down under that would be happy to sell you a dolphin striker. There's two ways to buy one. 1) you can buy the individual pieces which include a new mast step, horizontal dolphin striker rod, and the verticle rod that passes through the mast step. Just think of a H16 dolphin striker and you've got it. The sum of those parts comes to $226 US through Mariner Sails, the Dallas, Texas, Hobie Dealer. 2) You can purchase the dolphin stiker kit from a Hobie dealer for $96 US. However, the kit, which I have on my boat and I feel is adequate, has a steel cable that runs horizonatally across the boat below the front crossbar and a post that extends down from the front crossbar to hold it in place. If you can't find a dealer in Australia that will help you out, try Mariner sails, http://www.mariner-sails.com
. One member of their staff, John Webster, is a fellow Aussie and I'm sure he knows how to ship stuff home.
