The Garry Beers one is a Fender, I don't know if the CS sells bodies but why not start there?
I won't comment on the weight as it has been said a million times, but I will be shocked if Fender charges less than $3000 for the body alone, that isn't even counting the shipping to Australia.
You can buy Gary's bass here
. Personally I would much rather spend $25,000 elsewhere.
You could always call Fender CS and have them make you a replica, I imagine it would be cheaper but I assure you it will still be easily over $10,000, probably over $15,000. It costs almost $8k for a left handed jazz bass through the Fender CS.
