It occurred to me a month or so ago that the most dangerous animals in Australia other than humans might be the introduced animals:
- dog, bee, cattle, horse, feral pig, camel, water buffalo, sheep, goat, cat
rather than native animals:
- saltie, taipan, other snakes, red back, funnel web, jellyfish, cone snail, shark, devil, cassowary, kangaroo, stingray, blue-ringed octopus, stonefish, magpie
or mosquito?
What do you think?

“In summary, dog attacks result in more than 2,000 hospital admissions per year in Australia.”
“It was estimated in 1991 there were up to 30,000 people going to hospital annually because of domestic dog attacks in Australia.”

People in Melbourne who attended hospital emergency over a period of two years because of bites by mammals, “509 were dog bites, 122 were cat bites, 36 were human bites, and the remaining 50 were by monkey, rat, possum and bat.” “48% of dog bites required surgery, 34% of cat bites, 31% of human bites, and 22% of bites from other species”.

“The estimated incidence of snakebites annually in Australia is between 3 and 18 per 100,000 with an average mortality rate of 0.03 per 100,000 per year”
“3,520 Australians were hospitalised due to contact with a venomous animal or plant in 2017–18. More than a quarter of these hospitalisations were caused by bee stings (26%), almost one-fifth were caused by spider bites (19%), with redbacks the most common spider involved, and 17% were due to venomous snakes, including 215 brown snake bites. Nineteen people died due to venomous bites and stings in 2017–18.”
“A survey of Agriculture workers in 2009–10 found 17,400 had incurred a work-related injury or illness in the previous 12 months. Bitten or struck by cattle accounted for 9% of farm hospitalisations. For women from July 2006 to June 2009, 13% of farm hospitalisations involved females who had been injured in a horse-related incident with a further 6% having been Bitten or struck by horse and 10% Bitten or struck by cattle.”
“From 2015 to 2018, crocodiles in Australia killed a total of four people … average of two per year.” I count seven non-fatal crocodile attacks from Oct 2019 to Oct 2020. “in Australia, about 25% of saltwater crocodile attacks are fatal”.
