Contact Simon in the surf shop in Merimbula and see what he can do for you.
Ask him for Steve's number (the plumber) and see what he can do for you.
And then try Dave in the surf shop in Pambula.. Good luck..

You could just order a new 11' NSP and they're pretty cheap band new.. One of those would be a good starter and you could use it also on the river and inlet.
Any idea what type of board that you're looking for?
You could also call the RPS and SHQ shops here in Melbourne and see what demo boards that they have for sale.
