Animal activists have backtracked on claims they are sabotaging Western Australia's controversial shark drumlines, as they released video of a confrontation with the fisherman being paid by the state government to kill them.
As authorities repeated warning about potential massive fines for individuals or groups tampering with the baited hooks, a group of "anti-cull" activists made a show of strength on the steps of state parliament.
Led by Greens MP Lynn MacLaren, activists accused the contracted fisherman of misidentifying the shark caught early on Australia Day, while also decrying his method of euthanasing the shark - a .22 shotgun.
They refused to confirm they had removed bait from the hooks placed along beaches near Meelup and Dunsborough, claiming it would negatively impact their campaign against the policy.
The video released showed activists confronting the contractor, who is heard identifying the catch as a bull shark.
Shark Conservation president Ross Weir said its markings and teeth identified it as female tiger shark.
He also claims it could be under the three metres specified in the government catch-and-kill order.
"This individual has not been adequately trained, and we are calling on the state government to stand down the tender operator," Mr Weir said.
"He is using an inadequate firearm to euthanase these animals. It is not powerful enough, and four shots into a tiger shark is not a humane manner of dispatching the animal."
After saying on Monday groups had been removing bait from the lines, Mr Weir refused repeatedly to repeat his claim.
"We have had no contact with police, and have not broken the law. We are pursuing non-violent, direct action, legal tactics - but we will push the boundaries," Mr Weir said.
Anyone tampering with the equipment could face penalties of 12 months' jail for individuals and a $25,000 fine, while groups could be fined $50,000.
Reports suggest five drumlines checked on Tuesday morning were without bait.
Ms MacLaren said she was attempting to build a legal case against the policy and the tender process, backed by Jeff Hansen, the managing director of Sea Shepherd.
"We are seeking advice and help, and with help we have written asking there be a environmental impact assessment done on what is happening," Mr Hansen said.
Under the policy introduced following a string of fatal attacks in WA waters in recent years, any great white shark, tiger shark or bull shark longer than three metres that is caught on drum lines set by a commercial fisherman in the South West region or by the Department of Fisheries in the metropolitan area will be put down.
With Sir Richard Branson in the anti-kill corner, comedian Ricky Gervais is continuing his social media campaign against the program.
"You can kill any shark that gets out of the sea and starts killing us in our natural habitat of streets and pubs and internet cafes. Deal?," he tweeted.
"I love everything about Australia. The people, the attitude and especially the wildlife. Please protect your sharks. They were there first."
