Most shark attacks in Australia occur in New South Wales
Australia has one of the world's most comprehensive shark safety programs, balancing public safety with marine conservation goals. The country has implemented various shark mitigation strategies, including aerial surveillance, drone monitoring, acoustic tagging, and the use of personal deterrent devices. Despite these measures, shark attacks continue to occur, and Australia reported the second-highest number of total shark-related incidents worldwide.
The high number of shark attacks in New South Wales can be attributed to several factors. The state has a long coastline, providing extensive opportunities for shark interactions. Additionally, the popularity of water-based activities such as surfing and diving increases the chances of human-shark encounters. The use of certain beaches for activities such as surfing and swimming can also attract sharks, as they follow schools of fish or search for cooler water near the coast, where there is likely more food available.
New South Wales has invested in initiatives to reduce shark bites and protect its tourism industry. The state government allocated AU$16 million to this effort, implementing measures such as SMART drumlines and barrier nets. These strategies aim to strike a balance between public safety and the conservation of sharks, which play a vital role in maintaining the health of marine ecosystems.
While shark attacks can be traumatizing for victims and bystanders, it is important to remember that they are rare. Most incidents are cases of mistaken identity, as sharks confuse humans with their natural prey. By taking precautions, such as avoiding swimming far from shore or in dirty water, and not wearing jewellery or reflective clothing while in the water, the risk of a shark attack can be further reduced.

Most fatalities occur in Western Australia
Shark attacks are rare in Australia, but when they do occur, they can be traumatic events for both victims and bystanders. Since 1791, there have been over 622 unprovoked shark attacks in the country, with most recorded attacks taking place in New South Wales. Despite this, Western Australia has seen the most fatalities.
The Australian Shark-Incident Database has recorded 237 fatal shark attacks between 1791 and April 2018, with 11 additional fatal attacks in 2020 and 2021. While the majority of these incidents occurred in New South Wales, with 214 attacks, Western Australia has reported the highest number of fatalities. This disparity in the number of attacks and fatalities between the two states is notable and warrants further investigation.
The high number of shark attacks in New South Wales can be attributed to the state's popular surf beaches and the presence of prey such as seals and fish, which sharks may mistake for humans. To enhance shark safety, New South Wales has implemented various measures, including SMART drumlines and barrier nets. These measures aim to reduce the risk of shark attacks and protect both the public and the marine ecosystem.
On the other hand, Western Australia has taken a different approach to shark mitigation. The state has experimented with personal deterrent devices, which may include electronic deterrents, the Rpela, SharkBanz bracelet, and Chillax Wax. While these devices may not fully prevent shark bites, they can be effective when combined with other strategies such as drones and acoustic tracking. It is worth noting that Western Australia's unique marine environment and shark species may contribute to the higher number of fatalities.
To further prevent shark attacks and reduce their impact, Australia has implemented comprehensive shark safety programs and incident response protocols. These include rapid response teams, improved first aid capabilities, and enhanced mobile coverage at popular surfing locations. Additionally, states like South Australia have invested significant funds in new prevention measures, such as surveillance hubs and trauma kits at busy beaches. By continuously refining these protocols and public education efforts, Australia maintains a balance between public safety and marine conservation.

Shark attacks have increased from 9 per year between 1990-2000 to 22 per year from 2010-2020
Shark attacks in Australia have witnessed a notable surge, with the average annual number rising from 9 shark bites per year during the 1990s decade to 22 bites per year in the 2010s. This increase in shark attacks, specifically in Australia, is a subject of ongoing debate among researchers.
One school of thought attributes this rise to the swelling population density along coastal areas, coupled with an increase in aquatic recreational activities like surfing and diving. The allure of Byron Bay, a renowned surfing and fishing destination, exemplifies this trend. Its crystal-clear waters and abundant marine life, including mackerel and flathead, attract both enthusiasts and predators alike.
Environmental factors also play a role in this phenomenon. Variations in water temperature, declining water clarity in certain regions, and the broader impact of climate change are all considered contributing factors to the rise in shark bite incidents. The impact of climate change is particularly evident in the increased rainfall in Byron Bay, causing the Richmond River to flood and discharge a feast for sharks, including unwanted fish dumped by the prawn industry.
Additionally, the unique characteristics of certain shark species cannot be overlooked. Bull sharks, for instance, possess the rare ability to thrive in both saltwater and freshwater environments, enhancing their potential for dangerous encounters with humans. Tiger sharks, historically responsible for the second-highest number of attacks, are drawn to shallow waters and are easily provoked.
While the reasons behind the increase in shark attacks are multifaceted, it's important to remember that sharks do not inherently seek out humans as prey. Their instinctual response to splashing, activity, and the scent of blood in the water may inadvertently lead them to popular swimming and surfing spots, resulting in unfortunate but often unintentional encounters with humans.

Shark netting has reduced deaths in New South Wales since 1937
Shark attacks are a common concern for beachgoers in Australia, with the country reporting the second-highest number of total shark-related incidents in the world. Between 1791 and April 2018, there were 1068 shark attacks in Australia, 237 of which were fatal. New South Wales, in particular, has historically struggled with shark attacks, recording the highest number of attacks in the country between 1990 and 1999, with 73 attacks out of a total of 186 reported incidents.
To address this issue, New South Wales Fisheries developed shark net meshing in 1937, following a series of fatal shark attacks off Sydney beaches in the preceding years. The meshing was designed to catch large sharks as they swam within range of the surf, rather than enclose a body of water, as barrier nets cannot withstand the surf zone. The program was initially very successful, capturing over 600 sharks in its first year of operation off just a few Sydney beaches. Over time, the number of sharks caught declined, and today the New South Wales meshing annual average catch is 143 sharks, with many of these being released alive.
The use of shark nets has proven effective in reducing shark attacks in New South Wales. Before the introduction of nets in 1936, there was an average of one fatal shark attack per year in the state. Since then, there has been only one fatal attack on a protected beach, which occurred in 1951. This reduction in fatalities is especially notable given the significant increase in the human population of New South Wales and the corresponding rise in beachgoers.
However, the use of shark nets has also faced criticism due to its impact on the ecosystem. Environmental groups have called the New South Wales net program "outdated and ineffective," arguing that it does not adequately protect swimmers while causing significant harm to marine life. Between September 2017 and April 2018, more than 403 animals, including critically endangered sharks, dolphins, sea turtles, and other marine creatures, perished in the nets in New South Wales.

The Australian Institute of Marine Science advises against wearing jewellery when swimming
Shark attacks are a serious issue in Australia, with the country reporting the second-highest number of total shark-related incidents worldwide. The Australian state with the most shark attacks is New South Wales, specifically in the popular tourist spot of Byron Bay. With over 2 million visitors annually, Byron Bay has seen almost one out of five (16%) of all recorded shark attacks in Australia. The increase in attacks in this area is partly attributed to the fishing industry, with blood and discarded fish attracting sharks, as well as the presence of rivers and strong currents.
To address the issue of shark attacks, the Australian Institute of Marine Science advises swimmers to take several precautions. One recommendation is to refrain from wearing jewellery when swimming. This advice is supported by data from the Australian Shark-Incident Database, which has recorded over 1,100 individual investigations of shark-bite cases since 1791. The database helps evaluate the context and potential causes of shark bites, aiding in the development of preventive measures.
The recommendation to avoid wearing jewellery when swimming is based on the understanding that jewellery can increase the risk of a shark attack. Jewellery, especially metal items, can create a reflective surface that may attract the attention of sharks. Additionally, some types of jewellery, such as necklaces or bracelets, can dangle and move in the water, resembling the movements of prey. This similarity in motion could inadvertently attract curious sharks, increasing the likelihood of an encounter.
Furthermore, wearing jewellery while swimming can pose a safety hazard in the event of a shark attack. Jewellery can get entangled in a shark's teeth or gills, potentially causing injury to both the swimmer and the shark. If a person is wearing jewellery and becomes a victim of a shark attack, the jewellery could also complicate rescue and medical treatment, especially if it is difficult to remove. Therefore, by not wearing jewellery, swimmers can reduce the risk of accidental harm to themselves and the sharks.
In addition to the advice provided by the Australian Institute of Marine Science, there are other precautions that swimmers can take to reduce the risk of shark encounters. These include avoiding swimming far from the shore, near the mouth of a river, or in dirty water. It is also recommended to stay out of the water if there are people fishing nearby or if you have any bleeding wounds. By following these guidelines, swimmers can minimise their chances of encountering sharks and improve their overall safety while enjoying the water.
