Most waveriders from the Adelaide area can't resist the call of the desert, but rarely go further than the Eyre Peninsula. Those that make the journey as far as Penong (?The Rock Hole?), head another 21k's (13mi) south down a white lime dirt road, to Point Sinclair. The most southern spot is an outside break called Witzig's, named after Paul Witzig, the filmaker/journo who was one of the first to scope out this area. It is a powerful left with dredging takeoffs and can peel off for long distances when lined up on a moderate S-SW swell. Highly exposed.
Don't even think about it unless you are confident in your abilities. Very shallow and lots of water moving.
