SUP Animals / Surf Animals has a few I think. He's snapped a couple, and kept them in his garage... unless he's cleaned them out...
Otherwise, try ringing around... Ring maybe Force 9... Maybe try Shaun Wilde on the northern beaches...
I've only ever snapped 1... I paid $250 to get it put back together, but I had fallen out of love with it by then, and sold it to OceanBlue64 from here, for $250. So on that basis, you should be getting them for free... ?
