Horses are Australia's deadliest animal
Horses: Australia's Deadliest Animal
When most people think of dangerous Australian animals, they imagine venomous snakes, scary spiders, or perhaps even crocodiles. However, the animal that has caused the most human deaths in Australia over the past two decades is the horse.
Between 2000 and 2010, horses were responsible for 74 deaths, with that number rising to 77 between 2001 and 2021, and even as many as 222 according to some sources. This makes horses the deadliest animal in Australia, with the number of fatalities they cause far surpassing that of any other creature. The majority of horse-related deaths occur due to falls, with 36% involving trail or general horseback riding and 15% involving horse racing.
While it is true that Australia is home to many dangerous creatures, the country also has a strong equestrian culture, with humans riding horses for transport and recreation for thousands of years. This helps explain why horses are involved in so many fatalities.
In comparison to horses, cows, the second deadliest animal in Australia, killed 33 people between 2000 and 2010, and 92 people between 2001 and 2021. Dogs, the third most deadly, caused 27 deaths between 2000 and 2010, and 82 deaths between 2001 and 2021.
Interestingly, despite their fearsome reputation, crocodiles were only responsible for 9 fatalities between 2000 and 2010 and 25 fatalities between 2001 and 2021, placing them 8th on the list of Australia's deadliest animals. Similarly, snakes, for which Australia is known to have many, caused 27 deaths between 2000 and 2013 and 50 deaths between 2001 and 2021.

Cows are the second most deadly
Cows, bulls, and other bovines killed 92 people in Australia, and 83.7% of them were men. Cow-related deaths usually occur from "blunt force contact" with the animal, according to coroner data. In the UK, 76% of people killed by cows were farm workers, whereas in Australia, cow-related deaths are less common because walking routes are mostly in national parks rather than farmland.
Cows are not the only surprising animal to be among Australia's most deadly. Horses, including ponies and donkeys, are the most deadly animal in Australia, causing 77 deaths in 10 years, mostly related to falls. Dogs are the third biggest killer, causing 27 deaths, mostly in children under four years old and the elderly.
Despite their fearsome reputation, crocodiles are not among the top three most deadly animals in Australia. Between 2001 and 2021, there were 25 crocodile-related deaths in Australia, with 17 in the Northern Territory and seven in Queensland.

Bees kill as many people as sharks
While Australia is known for its venomous snakes, scary spiders, and dangerous saltwater crocodiles, the animals that pose the biggest threat to human life might not be the ones you expect. Horses, including ponies and donkeys, are the most deadly animal in Australia, causing 77 deaths in 10 years, mostly due to falls. Cows, including bulls and cattle, are the second most deadly, causing 33 deaths between 2000 and 2010, 16 of which were caused by motor vehicle accidents.
Interestingly, bees kill as many people as sharks in Australia, with 16 deaths attributed to each between 2000 and 2010. Bees are more likely to be deadly if you are allergic to their venom, with nearly 80% of deaths occurring in adults over 40 and men being twice as likely as women to develop hypersensitivity. While it's important to be cautious around bees, it's worth remembering that other factors, such as heart disease, pose a much greater risk to human health than bee stings or shark attacks.
In fact, according to Professor John Dunn of the University of Adelaide's School of Psychology, our perception of risk is often influenced by the availability of information and dramatic news stories, leading us to overestimate the probability of certain events occurring. This may explain why many people fear sharks and spiders more than horses or cows, even though the latter are responsible for significantly more deaths in Australia.
When it comes to animal-related deaths in Australia, it's important to consider the whole picture. While bees and sharks can be dangerous, they are not the most significant threats, and our interactions with common animals like horses and cows can often lead to more fatalities.

Cassowaries are the world's most dangerous bird
While horses are the deadliest animal in Australia, causing almost a third of deaths by animals, cassowaries are considered the world's most dangerous bird. Native to Northern Australia, New Guinea, and surrounding islands, cassowaries are shy and hard to spot in their natural rainforest habitats. They are also surprisingly adaptable, making them the largest urbanised birds in the world.
Cassowaries are descended from dinosaur ancestors and are extremely powerful. They can stand as high as six feet and weigh up to 160 pounds. These large birds cannot fly, but their powerful legs enable them to move at great speeds, up to 50 km (31 miles) per hour. They are also strong swimmers and can move quickly on both land and water.
Cassowaries have a reputation for being dangerous to people and domestic animals. During World War II, American and Australian troops in New Guinea were warned to avoid them. They have been observed to attack when provoked or angered, and their innermost toe bears a long, dagger-like nail capable of slashing and eviscerating with ease. There are many records of natives being killed by this bird, and one famous attack in 1926 resulted in the death of a teenage boy.
While human fatalities from emus are extremely rare, cassowaries are considered more dangerous due to their propensity for aggression and their powerful physical attributes.

Cats have caused 12 human deaths
While cats are widely known for killing birds and other wildlife, they are not usually known for killing humans. However, according to data from the National Coronial Information System, cats have been responsible for 12 human deaths in Australia between 2001 and 2021. This makes cats a more significant cause of human deaths than crocodiles, which were the eighth most deadly animal in the country over the past 20 years.
When considering the deadliest animals in Australia, it is worth noting that horses, including ponies and donkeys, were responsible for the most human deaths, with 77 deaths in 10 years, mostly from falls. Cows, including bulls and other bovines, were the second most deadly, causing 33 deaths between 2000 and 2010, and 92 deaths in the past 20 years. The majority of these deaths were due to blunt force contact with the animal, according to coroner data.
Dogs were the third biggest cause of human deaths in Australia, with 27 deaths, most of which occurred in children under four and the elderly. Kangaroos were also responsible for indirect deaths, causing 18 deaths between 2000 and 2010, mostly related to car accidents. Bees killed as many people as sharks (16 each), and snakes caused 14 fatalities, with crocodiles just behind at 9 fatalities.
While cats may not be the first animal that comes to mind when thinking of deadly creatures in Australia, the data shows that they have indeed been responsible for a small number of human deaths in the country. It is important to consider that the number of deaths caused by any animal is influenced by various factors, including the prevalence of the animal, human interaction with them, and the potential for accidental or intentional harm.
