What You'll Learn
Shark species in Western Australia
Western Australia is home to a diverse range of shark species, from the mighty whale shark to the diminutive pygmy shark. The waters off the Western Australian coast offer a rich habitat for these marine predators, and some species have even gained international notoriety due to their presence in these waters.
One of the most well-known shark species in Western Australia is the great white shark (*Carcharodon carcharias*)*. This species is the largest flesh-eating shark in the world, growing up to six metres in length. Great white sharks have a preference for the cooler waters along the southern coastline of Australia, including Western Australia. They are known for their appetite for marine mammals such as humpback whales and sea lions, and unfortunately, they are responsible for the majority of shark attacks worldwide. Great white sharks have been a protected species in Western Australian waters since 1999, and their numbers are believed to have increased in the region.
Tiger sharks (*Galeocerdo cuvier*) are another significant species found in Western Australian waters. They can reach lengths of six metres and are known for their scavenging behaviour, feeding on a variety of prey items ranging from whales and seals to stingrays and jellyfish. While they are typically associated with the tropics of northern Australia, tiger sharks have been recorded as far south as Cape Leeuwin in Western Australia.
The hammerhead shark (*Sphyrna mokarran*) is easily recognisable by its distinctive hammer-shaped head. This species patrols the northern coastline of Australia and has a particular fondness for feeding on rays, using its unique head shape to pin them to the ocean floor.
The grey nurse shark, known for its fearsome appearance due to exposed, razor-sharp teeth, is found in all Australian waters except Tasmania. Despite its intimidating looks, it is not considered a dangerous species to humans.
In addition to these larger species, Western Australia is also home to smaller shark species such as the euprotomicrus bispinatus, which grows to only one foot in length. This tiny shark inhabits the warm, deep waters of Western Australia during the day, venturing to the surface at night to feed on small fish.
The presence of these shark species in Western Australia has led to the region gaining a reputation for shark encounters and attacks. However, it is important to remember that sharks are an integral part of the marine ecosystem and play a crucial role in maintaining its balance.

Shark attacks in Western Australia
Western Australia is home to more than 100 shark species, including great white sharks, tiger sharks, lemon sharks, sandbar sharks, and hammerheads. The region has gained an international reputation as the deadliest place in the world for fatal shark attacks, with 20 great white shark attack fatalities since 1995.
While the risk of shark attacks in Western Australia is generally considered low, there has been a consistent increase in attacks since 2000, with a significant spike during the whale migration season. This correlation suggests that great white sharks are attracted to the abundance of whale calves and adult carcasses during this period.
In recent years, there have been several notable shark attacks in Western Australia. In November 2013, surfer Chris Boyd was fatally attacked by a great white shark off the coast of Gracetown. In June 2012, a 62-year-old man named Martin Kane had a close encounter with a great white shark while kayaking off Mullaloo Beach but escaped with only minor injuries. In October 2011, a 32-year-old American tourist was killed by a great white shark while diving off Rottnest Island.
Some of the beaches in Western Australia that have witnessed shark attacks include Cottesloe Beach, Perth's Port Beach, Cable Beach, Kelp Beds at Wylie Beach, Mindarie Marina, Falcon Beach, Cheynes Beach, and Stratham Beach.
To address the increasing number of shark incidents, Western Australia has established a dedicated shark response unit to collaborate with first responders and initiated debates around shark culling as a potential mitigation strategy.

Whale migration and shark activity
Whale Migration in Western Australia
Each year, around 60,000 humpback whales migrate from the icy waters of Antarctica to the warmer waters of northern Australia. This journey, spanning approximately 5,000 kilometres, takes place from January to March and marks the world's longest mammal migration. During this period, the whales mate, calve, and nurture their young.
The whale migration path along the Western Australian coast varies. Some whales travel up the west coast, passing through renowned locations such as Margaret River, Exmouth, Ningaloo Reef, and the Kimberley region. Augusta, with its picturesque Flinders Bay, is recognised as one of the best spots to witness humpback whales on their northern migration.
Shark Activity in Western Australia
Western Australia is known for its diverse shark population, with over 29 species inhabiting its waters. The great white shark is particularly notable for its presence in the region. Shark Bay, located 800 kilometres north of Perth, is a UNESCO World Heritage Site renowned for its rich marine life, including tiger sharks, lemon sharks, sandbar sharks, and hammerheads.
There is a perceived correlation between whale migration and shark activity in Western Australia. The recovery of whale populations, including humpbacks, has led to speculations about a potential increase in great white shark attacks. The majority of non-fatal shark attacks in Western Australia have occurred during the whale migration season. This correlation suggests that great white sharks may be attracted to the abundance of food sources, such as whale calves and adult carcasses, during the migration period.
The Impact of Whale Migration on Shark Activity
The increase in whale numbers provides a bountiful food source for scavengers like great white sharks. As whales migrate along the Western Australian coast, sharks may follow the pods, leading to an increased presence of sharks in specific areas. This correlation has sparked debates about shark culling and the need for further research to understand the complex relationship between whale recovery and shark behaviour.
In summary, whale migration and shark activity in Western Australia are interconnected, with whale migrations potentially influencing the movement and behaviour of sharks, particularly great white sharks. The presence of whale calves and the recovery of whale populations may contribute to increased shark activity, highlighting the complex dynamics between these marine species in Western Australian waters.

Shark sightings in Western Australia
Western Australia is known for its beautiful beaches, but the region has gained an international reputation as the deadliest place in the world for fatal shark attacks. There have been 20 great white shark attack fatalities in Western Australia since 1995, with a majority of these occurring during the humpback whale migration season. Whale sharks, tiger sharks, lemon sharks, sandbar sharks, and hammerheads are among the 29 shark species that call the World Heritage Site of Shark Bay home. Ningaloo Reef, located 1,200km north of Perth, is another hotspot for shark sightings, particularly whale sharks that feed there every year between March and June.
The Western Australian Government has implemented a strong, evidence-based shark mitigation program to improve beach safety. The SharkSmart WA app provides users with near real-time information on shark activity, including current alerts and warnings. Surf Life Saving WA also plays a crucial role in beach safety, providing frequent updates on shark sightings via Twitter and helicopter beach patrols.
Despite these efforts, shark sightings and attacks continue to be a concern in Western Australia. Between May and December 2017, Surf Life Saving WA received over 1,400 shark reports, primarily of bronze whalers, white pointers, and tiger sharks. Perth's Cottesloe Beach was closed in November 2017 after a shark sighting, and the Rottnest Channel Swim was disrupted in February by a four-metre great white shark.
To stay safe, it is recommended to check for shark activity before visiting the beach and to report any shark sightings to the Water Police. If you see a shark while in the water, leave the water as quickly and calmly as possible, avoiding excessive splashing or noise.

Shark conservation in Western Australia
Western Australia is home to a diverse range of shark species, with some of the world's most shark-infested waters. The state has gained an international reputation as the deadliest place for fatal shark attacks, with 20 great white shark attack fatalities since 1995. Despite this, conservation efforts in Western Australia are critical to protecting these keystone species.
One of the key focuses of shark conservation in Western Australia is the protection of whale sharks, which are the state's marine animal emblem. Whale sharks are harmless filter feeders that can reach up to 18 metres in length and are protected under both state and federal laws. Ningaloo Marine Park, located off the northwest coast of Western Australia, is one of the few places in the world where whale sharks regularly appear in near-shore waters. The park has seen a significant increase in visitors seeking to swim with whale sharks, with numbers rising from 1,000 in 1993 to over 36,000 in 2022. To manage this influx, the Western Australian government has introduced a licensing system for commercial tour operators and established interaction protocols to reduce disturbances to the whale sharks.
Another important conservation site is Shark Bay, located at the westernmost point of the Australian continent. Shark Bay became a UNESCO World Heritage Site in 1991 due to its natural splendour and diverse ecosystems. The bay is home to over 300 species of marine animals, including 29 types of sharks. It features vast seagrass beds, which are the largest and richest in the world, providing a haven for endangered green and loggerhead turtles and one of the world's most significant strongholds for the protection of dugongs. Shark Bay also supports five globally threatened mammal species and several threatened plant and reptile species. Conservation efforts in Shark Bay include zoning and designating conservation areas, restricting public access, managing fisheries, and increasing staffing.
In recent years, Western Australia has faced a challenging balance between shark conservation and public safety. With a significant increase in shark sightings and attacks, the issue of shark culling has become a highly debated topic. However, conservation organisations like the Australian Marine Conservation Society have worked to stop shark culling and promote alternative solutions. They have also successfully reduced the shark catch in the Great Barrier Reef and established net-free zones to protect sawfish.
To address the issue of accidental bycatch, where endangered sharks are caught unintentionally, Australian fisheries are encouraged to modernise their methods. This includes implementing the use of cameras on board boats to monitor and reduce the accidental catching of endangered species. Additionally, public education and awareness play a crucial role in shark conservation. Many Australians are unaware that "flake," a common term for shark meat, often refers to endangered shark species. By promoting sustainable seafood alternatives and providing information about shark conservation, organisations aim to reduce the consumption of endangered shark meat.
