The great white shark, also known as the white shark, white pointer, or simply great white, is a species of large mackerel shark which can be found in the coastal surface waters of all the major oceans. It is the only known surviving species of its genus Carcharodon. The great white shark is notable for its size, with the largest preserved female specimen measuring 5.83 m (19.1 ft) in length and around 2,000 kg (4,400 lb) in weight at maturity. However, most are smaller; males measure 3.4 to 4.0 m, and females measure 4.6 to 4.9 m on average. According to a 2014 study, the lifespan of great white sharks is estimated to be as long as 70 years or more, well above previous estimates, making it one of the longest lived cartilaginous fishes currently known. According to the same study, male great white sharks take 26 years to reach sexual maturity, while the females take 33 years to be ready to produce offspring. Great white sharks can swim at speeds of 25 km/h (16 mph) for short bursts and to depths of 1,200 m (3,900 ft).
A shark attack is an attack on a human by a shark. Every year, around 80 unprovoked attacks are reported worldwide. Despite their rarity, many people fear shark attacks after occasional serial attacks, such as the Jersey Shore shark attacks of 1916, and horror fiction and films such as the Jaws series. Out of more than 500 shark species, only three are responsible for a double-digit number of fatal, unprovoked attacks on humans: the great white, tiger, and bull. The oceanic whitetip has probably killed many more shipwreck and plane crash survivors, but these are not recorded in the statistics. Humans are not part of a shark's normal diet. Sharks usually feed on small fish and invertebrates, seals, sea lions, and other marine mammals. A shark attack will usually occur if the shark feels curious or confused.
Port Lincoln is a city on the Lower Eyre Peninsula in the Australian state of South Australia. Known as Galinyala by the traditional owners, the Barngarla people, it is situated on the shore of Boston Bay, which opens eastward into Spencer Gulf. It is the largest city in the West Coast region, and is located approximately 280 km (170 mi) from the state's capital city of Adelaide.
A shark net is a submerged section of gillnets placed at beaches designed to intercept large marine animals including sharks, with the aim to reduce the likelihood of shark attacks on swimmers. Shark nets used are gillnets which is a wall of netting that hangs in the water and captures the marine animals by entanglement, however only around 10% of catch is the intended target shark species. The nets in Queensland, Australia, are typically 186m long, set at a depth of 6m, have a mesh size of 500mm and are designed to catch sharks longer than 2m in length. The nets in New South Wales, Australia, are typically 150m long, set on the sea floor, extending approximately 6m up the water column, are designed to catch sharks longer than 2m in length. Shark nets do not create an exclusion zone between sharks and humans, and are not to be confused with shark barriers.
The Eyre Peninsula is a triangular peninsula in South Australia. It is bounded by the Spencer Gulf on the east, the Great Australian Bight on the west, and the Gawler Ranges to the north.
Shark cage diving is underwater diving or snorkeling where the observer remains inside a protective cage designed to prevent sharks from making contact with the divers. Shark cage diving is used for scientific observation, underwater cinematography, and as a tourist activity. Sharks may be attracted to the vicinity of the cage by the use of bait, in a procedure known as chumming, which has attracted some controversy as it is claimed to potentially alter the natural behaviour of sharks in the vicinity of swimmers.
Streaky Bay is a coastal town on the western side of the Eyre Peninsula, in South Australia just off the Flinders Highway, 303 km (188 mi) north-west of Port Lincoln and 727 km (452 mi) by road from Adelaide. At the 2016 census, Streaky Bay recorded a population of 1,378.
Gracetown is a small town in Western Australia. It is located 269 kilometres (167 mi) south of the Perth central business district, and 21.5 kilometres (13.4 mi) north-west of the township of Margaret River in the Augusta-Margaret River Shire Council area on the coast at Cowaramup Bay.
The Mid West Football League was an Australian rules football competition based in the Eyre Peninsula region of South Australia, Australia. It was wound up prior to the 2021 season after Wudinna and Central Eyre merged and transferred to the Eastern Eyre Football League.
Baird Bay is a small fishing village located 50 kilometres south of Streaky Bay on the west coast of Eyre Peninsula in South Australia. It is situated on the east coast of a bay named Baird Bay which opens into the north end of Anxious Bay.
Perlubie is a locality in the Australian state of South Australia located on the west coast of Eyre Peninsula about 472 kilometres (293 mi) north-west of the state capital of Adelaide and about 24 kilometres (15 mi) north-east of the municipal seat of Streaky Bay.
Smoky Bay is a town and locality located in the Australian state of South Australia on the west coast of the Eyre Peninsula. Previously used as a port, the town is now a residential settlement and popular tourist destination known for its recreational fishing, with a boat ramp and jetty located in the town.
Between 1791 and April 2018 it was reported that there have been 1068 shark attacks in Australia with 237 of them being fatal.
Wildlife attacks in Australia occur every year from several different native species, including snakes, spiders, freshwater and saltwater crocodiles, various sharks, cassowaries, kangaroos, stingrays and stonefish and a variety of smaller marine creatures such as bluebottles, blue-ringed octopus, cone shells and jellyfish.
The Western Australian shark cull is the common term for a former state government policy of capturing and killing large sharks in the vicinity of swimming beaches by use of baited drum lines. The policy was implemented in 2014 to protect human swimmers from shark attack following the deaths of seven people on the Western Australian coastline in the years 2010 to 2013. National public demonstrations opposing the policy attracted international attention to the issue. In September 2014 the seasonal setting of drum lines was abandoned following a recommendation made by the Western Australian Environment Protection Authority. From December 2014 to March 2017, the special deployment of drum lines was permitted in cases where sharks were deemed to present a serious threat to public safety. This policy allowed the government of Western Australia to kill "high-hazard" sharks it found to be a threat to humans; the policy was criticized by senator Rachel Siewart for damaging the environment. In March 2017 the use of drum lines was abandoned by the newly elected West Australian state government. In August 2018 following continual shark attacks the West Australian state government reversed their position and announced a 12-month trial of "SMART" drumlines along Western Australia's South West coast, near Gracetown.
A shark barrier is seabed-to-surface protective barrier that is placed around a beach to protect people from shark attacks. Often confused with shark nets, shark barriers form a fully enclosed swimming area that prevents sharks from entering. Shark barrier design has evolved from rudimentary fencing materials to netted structures held in place with buoys and anchors. Recent designs have used plastics to increase strength, versatility and to reduce the environmental damage of bycatch.
There are a range of shark attack prevention techniques employed to reduce the risk of shark attack and keep people safe. They include removing sharks by various fishing methods, separating people and sharks, as well as observation, education and various technology-based solutions.
Shark culling is the deliberate killing of sharks by government authorities, usually in response to one or more shark attacks. The term "shark control" is often used by governments when referring to culls. Shark culling has been criticized by environmentalists, conservationists and animal welfare advocates—they say killing sharks harms the marine ecosystem and is unethical. Government officials often cite public safety as a reason for culling. The impact of culling is also minor compared to bycatch with 50 million sharks caught each year by the commercial fishing industry.
