Australia is known for its dangerous wildlife, including venomous snakes, spiders, crocodiles, and sharks. However, its neighbour New Zealand has a very different reputation when it comes to wildlife. While there are some potentially dangerous animals in New Zealand, such as sharks, spiders, and sea slugs, the country is considered one of the safest in the world in terms of wildlife. New Zealand has no land snakes, large predators, or venomous land animals, and even its few defensive creatures are relatively mild compared to those found in other countries. So, while it's always important to be cautious and aware of potential dangers, New Zealand's wildlife is generally not something to be feared.

What You'll Learn
Australia's most venomous animals
Unlike New Zealand, Australia is known for its venomous and deadly creatures. The country has more deadly snakes than any other country in the world. Its inland taipan snakes, box jellyfish, Sydney funnel-web spiders, stonefish, and European honey bees are among the most venomous of their kind.
The Sydney funnel-web spider, for instance, releases a neurotoxin that can kill a child in only 15 minutes. The blue-ringed octopus, which can be found in tide pools and coral reefs in Indo-Pacific waters, is another highly venomous creature. It has one of the most toxic venoms on the planet, causing paralysis within minutes, leading to respiratory issues and heart failure.
The stinging stonefish, found on Australia's reefs, is another venomous creature. The pain of its sting alone can be lethal, producing such extreme agony that the body goes into shock and the person dies.
The country's venomous snake population can also be attributed to the theory of continental drift, which suggests that Earth's continents experienced large-scale movement away from one another. When landmasses separated, Australia's snake population remained entirely venomous, while other continents retained populations of both venomous and nonvenomous snakes.
Other venomous creatures in Australia include the cone snail, whose sting could kill many adults, and the box jellyfish, which can kill a healthy adult in minutes.

New Zealand's dangerous animals
New Zealand is known for its natural beauty and diverse ecosystems, which can be explored with little concern about encountering dangerous animals. Unlike its neighbour Australia, New Zealand is not known for its deadly creatures. There are no large predators, venomous snakes, or dangerous insects in New Zealand. This makes outdoor activities and wilderness exploration in the country relatively safe.
However, there are still a few dangerous animals in New Zealand that one should be cautious of. These include spiders, sharks, marine animals, and wild boars. The chances of encountering these animals are relatively low, but it is important to be aware of them.
The Katipō spider is one of the rare venomous creatures found in New Zealand. It is extremely uncommon and shy, making human encounters rare. The redback spider is another venomous spider, but it is also rare and effective treatments are available in the rare case of a bite. The white-tailed spider, which has been introduced from Australia, is also found in New Zealand and has been known to cause necrotic lesions on rare occasions. However, recent research suggests that its bite is not as dangerous as previously thought.
Sharks are present in New Zealand's waters, but shark attacks are extremely rare. Great white sharks are the most dangerous in these waters. The bluebottle jellyfish, also known as the Portuguese man o' war, is another marine animal that can be found in New Zealand's waters. It is known for its severe sting, but it is small and difficult to spot in the water.
Wild boars can be found all across New Zealand, especially in forested areas. They can grow up to 6 feet in length and have large tusks that can cause substantial damage. They are generally not aggressive unless they feel threatened, but they are unpredictable, so it is important to keep your distance if you encounter one.
In addition to these animals, New Zealand is home to some unique insects like the Weta, which can look intimidating but are harmless. Sandflies are also common in some areas and can bite, but they do not transmit diseases. Overall, New Zealand is considered to be a safe destination when it comes to dangerous wildlife, and common sense and basic precautions can further minimise the risk posed by animals.

Australia's dangerous marine life
Australia is known for its dangerous marine life, with over 10,000 beaches along its 35,000 km coastline. Here are some of the most notable dangerous marine creatures found in Australian waters:
Box Jellyfish
The box jellyfish is considered one of the most venomous creatures on the planet. It has a transparent pale blue, box-like shape with tentacles that can reach up to three metres in length. Each tentacle contains approximately 5,000 stinging cells that release venom, causing extreme pain and, in some cases, cardiac arrest.
Irukandji Jellyfish
The Irukandji jellyfish is a smaller relative of the box jellyfish, only growing to the size of a human thumb. However, it can still deliver a life-threatening sting, causing severe headaches, muscle pain, nausea, and vomiting.
Blue-Ringed Octopus
The blue-ringed octopus is found in the temperate waters of southern Australia, hiding under rocks and in crevices during the day. While bites are very rare, they are extremely dangerous and can be fatal. Symptoms of a bite include difficulty swallowing, excessive salivation, tingling, numbness, headaches, and nausea.
Stonefish
Stonefish are considered the most venomous of all fish and are found in tropical waters along the Australian coastline. They are excellently camouflaged and rarely swim away when disturbed, instead relying on venomous dorsal spines that can pierce rubber-soled shoes. Their venom is extremely potent and can be fatal.
Lionfish
Lionfish, also known as scorpionfish, can be found in tropical and subtropical waters. They are aggressive and possess venomous spines that cause extremely painful stings. While not usually fatal, symptoms of a lionfish sting can include headaches, vomiting, seizures, paralysis, and breathing difficulties.
It is important to note that while Australia has its fair share of dangerous marine life, most encounters can be avoided by taking appropriate precautions. Following local guidelines, wearing protective gear like wetsuits or stinger suits, and staying informed about the marine life in the area can help minimize the risk of encountering these dangerous creatures.

Crocodiles in Australia
Australia is home to two species of crocodiles: the Saltwater Crocodile and the Freshwater Crocodile. Saltwater Crocodiles, or 'salties', are the largest of all living reptiles and can be found in estuaries and freshwater swamps across northern Australia. They can also venture inland during the breeding season and have been spotted along the Mulgrave River south of Cairns. With around 68 sharp teeth, these crocodiles are predators to anything they come across, including humans, smaller reptiles, fish, turtles, and birds. They are able to capture larger prey as well, including livestock, buffaloes, and adult humans. Saltwater Crocodiles can reach speeds of 10km per hour in water and can run on land at up to 11km in short bursts. They are also incredibly enduring, with some records showing they can travel up to 900 kilometres in one go.
The second species, the Freshwater Crocodile, also known as Johnstone's Crocodile, is much smaller and generally harmless to humans. They inhabit rivers, swamps, and billabongs in northern Australia.
The reason for the difference in behaviour between the two species may be due to their diets. Saltwater Crocodiles have a more diverse diet, including fish, birds, and mammals, while Freshwater Crocodiles primarily feed on fish and small invertebrates.
Saltwater Crocodiles have been protected since 1871 and their population is now estimated to be around 150,000 in the wild.
While New Zealand does not have any crocodiles, it is home to a few dangerous animals, including spiders, sharks, and marine animals. However, the chances of encountering these creatures are relatively low, and New Zealand is considered much safer than Australia when it comes to dangerous wildlife due to the lack of venomous snakes, large predators, and deadly insects.

Snakes in Australia
Unlike Australia, New Zealand is not known for its dangerous wildlife. The country's natural beauty and diverse ecosystems can be explored with little worry about encountering deadly creatures. While New Zealand does have some dangerous animals, such as the Katipo spider, the country lacks venomous snakes, large predators, and deadly insects. This makes outdoor activities and wilderness exploration in New Zealand much safer than in Australia.
Australia, on the other hand, is known for its dangerous snakes, with around 170 species of land snakes, some equipped with venom more toxic than any other snakes in the world. However, it is important to note that snake bites in Australia are quite rare, and since the development of anti-venom, fatalities have been low, with only four to six deaths per year on average. Here are some of the most dangerous snakes in Australia:
Inland Taipan
The inland taipan, also known as the fierce snake, is considered the most venomous snake in Australia and even globally. It is found in Australia's dry areas and its toxic venom is so strong that a single bite could potentially kill up to 100 adults. Despite being deadly, the inland taipan is shy and only attacks when it feels threatened.
Eastern Brown Snake
The eastern brown snake is one of Australia's most dangerous snakes and is responsible for more deaths every year than any other group of snakes in the country. Its venom is ranked as the second most toxic of any land snake in the world. They are fast-moving, aggressive, and known for their bad temper. They thrive in populated areas, particularly on farms in rural areas with mice.
Western Brown Snake
The western brown snake is said to be less aggressive than its eastern cousin, but it is still highly dangerous and part of the group of snakes that cause the most fatalities in Australia. They tend to be fast-moving and nervous in temperament. When disturbed, they will run for cover, striking quickly if cornered, and then making a quick escape. Their venom is not as toxic as the eastern brown's, but they deliver three times the amount.
Mainland Tiger Snake
The mainland tiger snake is responsible for the second-highest number of bites in Australia as they inhabit highly populated areas along the east coast, including some metropolitan areas of Melbourne. They are attracted to farms and outer suburban houses, where they hunt mice nocturnally. Bites from these snakes are fatal if untreated, causing pain, tingling, numbness, sweating, breathing difficulties, and paralysis.
