While the West Australian Government pushes for an extension of its controversial shark-kill policy, one passionate opponent is going to unusual lengths to fight it.
Not satisfied with protesting from the beach, young filmmaker Madison Stewart took her underwater camera to the baited drum lines off Perth beaches and filmed sharks caught up on the hooks.
The Byron Bay diver has swum with sharks around the world and has been outraged by WA's drum-line policy, which caught more than 170 sharks in a three-month period.
"The first time I'd been in the water with a tiger shark, in Australia, was a dead one, south of Perth," she said.
"That shouldn't be happening in Australia.
"People have a right to know what's going on."
Ms Stewart has had a "burning passion for sharks" since she began scuba diving at the age of 12.
According to her website, she never learnt to ride a push bike because her father thought the roads were too dangerous. He took her diving with sharks instead.
She says she never set out to be a conservationist, but today the home-schooled 20-year-old campaigns for shark conservation through her short films, urging people to respect the creatures, rather than fear them.
One of her biggest achievements, she says, has been successfully lobbying a major supermarket chain to stop stocking shark products sourced from the Great Barrier Reef.
Stewart was flown to WA by environmental group Sea Shepherd and was among activists shadowing Fisheries patrol boats in recent months.
Her latest video features an incident off Scarborough, a popular Perth beach, where activists were warned by Fisheries officers that they were acting illegally by handling a 3.2 metre tiger shark that had died on the lines.
Authorities allege the activists broke the Fish Resources Management Act by handling the shark, a protected fish, and obstructing officers trying to perform their duties.
Two of the activists were given written warnings, but no charges were laid.
They were also asked to hand over any video or still cameras in their possession, but Madison Stewart says her footage had already been taken away by a fellow activist.
She says she was also given a warning by the Fisheries officers that she is now choosing to ignore.
"I was told that if I was to release any of the footage that I took on that day, that I would be going to court for obstruction," she said.
The footage was posted online this week in a video which features graphic images of tiger sharks caught on drum lines.
One of the criticisms of the drum lines is that they have almost exclusively caught tiger sharks, when most of the recent fatal attacks off WA's coast are believed to have been by great white sharks.
Ms Stewart hopes her films will raise awareness about the policy and help to stop a planned, three-year extension of the shark cull, which is currently before the Federal Government for approval.
"I'm not going to sit here and tell you that sharks are harmless, that's not true," she said.
"But that doesn't mean the cull is going to stop that.
"Knowledge is the only thing that dispels fear and it's going to be the only thing that people can use to protect themselves."
The WA Government has declared the drum line program a success, with Fisheries Minister Ken Baston saying the program has restored the confidence of beachgoers.
