Baited hooks removed off Cottesloe for the Rottnest Channel Swim have been replaced as photos emerged of a big tiger shark caught on a drum line in the South West.
Three divers reported a 5.5m great white shark off Three Mile Reef near Ocean Reef yesterday and other divers left the water as the news spread quickly. The Westpac helicopter could not spot it.
Sea Shepherd and Animal Amnesty released pictures from Moses Rocks, near Margaret River and Gracetown, which they claimed showed inhumane treatment of tiger sharks.
Sea Shepherd Australia managing director Jeff Hansen said a tiger shark caught at Moses Rocks on Saturday threw up because it was so distressed while entangled.
He said they also filmed an undersize shark's head being hacked to free a hook and the shark sank on release.
A spokeswoman for Fisheries Minister Ken Baston said the minister was confident the contractor was working within his contract.
The Government would release catch data, she said.
