Shark culling

Shark culling is the deliberate killing of sharks by a government in an attempt to reduce shark attacks; shark culling is often called "shark control". These programs have been criticized by environmentalists and scientists—they say these programs harm the marine ecosystem; they also say such programs are "outdated, cruel, and ineffective". Many different species (dolphins, turtles, etc.) are also killed in these programs (because of their use of shark nets and drum lines)—15,135 marine animals were killed in New South Wales' nets between 1950 and 2008, and 84,000 marine animals were killed by Queensland authorities from 1962 to 2015.

Great white sharks are currently killed in both Queensland and New South Wales in "shark control" (shark culling) programs. Queensland uses shark nets and drum lines with baited hooks, while New South Wales only uses nets. From 1962 to 2018, Queensland authorities killed about 50,000 sharks, many of which were great whites. From 2013 to 2014 alone, 667 sharks were killed by Queensland authorities, including great white sharks. In Queensland, great white sharks found alive on the drum lines are shot. In New South Wales, between 1950 and 2008, a total of 577 great white sharks were killed in nets. Between September 2017 and April 2018, fourteen great white sharks were killed in New South Wales.

KwaZulu-Natal (an area of South Africa) also has a "shark control" program that kills great white sharks and other marine life. In a 30-year period, more than 33,000 sharks were killed in KwaZulu-Natal's shark-killing program, including great whites.

In 2014 the state government of Western Australia led by Premier Colin Barnett implemented a policy of killing large sharks. The policy, colloquially referred to as the Western Australian shark cull, was intended to protect users of the marine environment from shark bite incidents, following the deaths of seven people on the Western Australian coastline in the years 2010–2013. Baited drum lines were deployed near popular beaches using hooks designed to catch great white sharks, as well as bull and tiger sharks. Large sharks found hooked but still alive were shot and their bodies discarded at sea. The government claimed they were not culling the sharks, but were using a "targeted, localised, hazard mitigation strategy". Barnett described opposition as "ludicrous" and "extreme", and said that nothing could change his mind. This policy was met with widespread condemnation from the scientific community, which showed that species responsible for bite incidents were notoriously hard to identify, that the drum lines failed to capture white sharks, as intended, and that the government also failed to show any correlation between their drum line policy and a decrease in shark bite incidents in the region.
