Steve ,
In Carbon?,
no one in Tassie, in fact not even on mainland anymore.
There are a few in Tassie who have made their own and a few on mainland who have made customs for customers .
There are a couple who make in polyester not epoxy ( Stone surf design WA) ..
Nick stranger who used to make all the Island Energy boards still produces surfboards in his factory in Rokeby.

Or go modern production ,
Like the malibu customs - pay $2000 when you can get a very good production board for $1400
Also Sailboards in particular have very poor resale if custom.
