This will probably only be interesting to South Aussies, but there is a proposal for alternate shark cage diving sites. Ever since a great white shark was attacked by some killer whales (orcas) at the Neptune Islands in February, no great whites have been spotted. Diddums - poor old shark got a fright
Anyway, the shark cage diving industry is hurting and wants permission to try some new sites. I have nothing against shark cage diving, but several of the sites suggested, in particular the islands of the Sir Joseph Banks Group are popular sailing destinations. IMO, encouraging sharks to come inshore, whether for fishing or cage diving, is reckless and will serve only to increase the risk of shark attacks. Last year I was anchored off Wedge Island with half a dozen other yachties and some clown was chumming for sharks just down the beach.
Sharks belong offshore and shark cage diving should be limited to more remote locations only, such as the Neptunes and The Pages. The latter has the merit of being (partially) in a marine park and effectively already off limits.
