Hi Slayer,
As I said find a fiberglass supplies shop listed under the yellow pages. West Systems epoxy is available in Australia, or you can use one of the locally produced ones Ciba Geigy make it for sure but I can't remember the brand name - and no it's not Araldite. LOL
Although they do make that as well, but it's made by their adhesives branch. If I get a chance I'll go past my local supplier and get you the Aussie brand name.
