Shark culling (the killing of sharks) currently occurs in New South Wales and Queensland (in government "shark control" programs). These programs have damaged the marine ecosystem. Roughly 50,000 sharks have been killed by Queensland authorities since 1962, including in the Great Barrier Reef. Queensland's "shark control" program has been called "outdated, cruel and ineffective". The "shark control" programs in New South Wales and Queensland have killed thousands of animals, such as turtles and dolphins. In 2018, the Humane Society International filed a lawsuit against the government of Queensland to stop shark culling in the Great Barrier Reef.
