Great white sharks are a protected species in Australia, and state authorities were given a special exemption from Australia’s Environment Protection and Biodiversity Conservation Act to be able to kill them. The shark cull is a pilot program. If it were to continue after the April 30 trial period ends, there would have to be a full environmental act assessment.
