The Kangaroo
The kangaroo is Australia's national symbol; along with its smaller relative the wallaby. Kangaroos (or “roos”) are seldom seen during the day; particularly in hot weather.
They are not generally aggressive; however, males of larger species, such as reds, can be dangerous when cornered. In the wild they will grasp other males with their forearms, rear up on their muscular tails and pound their opponents with their hind feet; sometimes slashing them with their claws.
Kangaroos are a serious hazard to motorists driving, particularly when the sun has set. Kangaroos have little road sense, and often jump into the way of a car. They are attracted to car head lights. They are killed in disturbing numbers on WA roads; and inexperienced drivers need to be weary of this issue before setting off on a DriveWA adventure!
Kangaroos live in considerable numbers quite close to most towns in WA. They don’t merely reside in the outback. Suburbs such as Joondalup and Kinross (Approximately 30 minutes North of Perth city), are prevalent areas that the roo can be found. Edith Cowan University, in Joondalup, is home to a number of kangaroos!
The Emu
The Emu
The Emu is the world's second-largest bird. It is the flightless bird that is featured, alongside the Kangaroo, on the Australian coat of arms, and is found in large numbers in less inhabited areas of WA.
They may at times be seen quite close to towns. Emus are very mobile, and can also be a problem on the roads and tracks. They do a lot of damage to vehicles and create problems for cereal growers. They are now being farmed for their highly prized oil, eggs, hide, and meat. Many Emu farms are very interesting places to visit.
Other Australian Birds
There is an incredible assortment of birds in the outback. The parrots (28s - usually green blue and yellow, and Rosellas’ - a mixture of bright reds, yellows, blues and greens), are extremely beautiful to view in flight. The pink and grey Galah is an intelligent bird and a bit of an Ozzie icon. Someone acting like “a Galah” is an Australian slang term, and represents someone who is acting the fool.
Eagles
Eagles
These are beautiful and impressive birds. The various Eagles, Goshawks, Kites, Harriers, Falcons, and Kestrels are usually the most commonly seen of all outback birds.
The largest of all is the Wedge-tailed Eagle. Their name refers to its distinctively pointed, diamond shaped tail. With a wingspan approaching 3m, they soar high on the thermals whilst scanning the ground for prey, including rabbits and young kangaroos. Their eyesight is so keen, that they're thought to be able to see a rabbit quite clearly from a distance of 1.5km.
Please approach them with respect and great caution – if you hit an Eagle (particularly if it hits your windscreen) it can cause a lot of damage. In addition, if they are only ‘stunned’, rather than injured, be very careful of them when they wake up because they have big beaks and dangerous talons.
The Dingo
The Dingo
The Dingo, or wild dog, is considered a native animal to Australia. There are two theories of how they arrived on our shores; 1) they tagged along with early Aborigines migrating from South-East Asia; 2) they were introduced fairly recently by Indonesian fishermen.
Dingoes can interbreed with other species of dog. This is a major threat to their survival as a pure strain. Dingoes are most prevalent north and west of the Dog Fence, the world's longest man-made barrier. The fence is 1.4m and 2.4m high, and it runs for 5400km from the Gold Coast in Queensland to the Great Australian Bight in South Australia.
A pair of Dingoes acting together can kill dozens of sheep in a night; so any that make their way through the fence are vigorously pursued with bullets, traps, and poison baits. Although dingoes do prey on calves, their depredations aren't considered a serious threat to the beef/cattle industry.
Fauna to Avoid and Respect
Fauna to Avoid and Respect
Crocodiles
There are two species of crocodile in Western Australia; the larger saltwater Estuarine crocodile (called a “saltie”), and the smaller fresh water variety (called a “freshie”). Unfortunately, salties aren't confined to salt water - they can be found in freshwater habitats more than 200km inland.
Freshies are smaller than salties. Any crocodile over 3m should be regarded as a probable saltie. Freshies are more finely built. They have much narrower snouts and smaller teeth to suit their fish diet. Freshies are generally considered harmless to humans, but they have been known to bite in defence of their nests; so keep children and pet dogs at a distance.
Crocs seem to favour dog meat. They are a definite danger to dogs, and to people travelling with dogs. Both species of crocodiles were once hunted, almost to the point of extinction, but since they were proclaimed a protected species they have increased in number.
The most important rule to avoid being attacked by a croc: Stay out of the water whenever you're in saltie country!!
Snakes
Only about 10% of Australian snake species are dangerous, but there are some very deadly ones amongst them. The Tiger snake, death adders, copperheads, brown snakes, and red-bellied black snakes should also be avoided at all costs.
Many people spend months travelling in the outback without seeing a snake. This is because snakes tend to keep a low profile. To minimise your chances of being bitten:
- Always wear boots, socks, and long heavy-weight trousers when walking through undergrowth.
- Don’t walk in dry grass without shoes or long trousers in warm weather
- Tramp, or “stomp”, heavily (snakes will usually slither away in fear before you come near)
- Don't put your hands into holes and crevices
- Be extremely careful when collecting firewood (snakes love warm, dry places)
Most people are bitten while trying to kill a snake, or stepping over them. In the unlikely event that you see a live snake, walk away from it very quietly, or simply stand still until it escapes. Most snakes are generally very afraid of humans; however, if it feels cornered it may well strike in self defence.
Sea Snakes
There are 30 species of sea snakes in Australian coastal waters, and although their venom can be 10 times as toxic as that of a cobra, they're shy creatures and usually won't attack if left alone.
Snake Bite- First Aid
Snake Bite- First Aid
Contrary to popular belief, snake bites do not cause instantaneous death. A snake bite is often shallow and injects little venom. This is because snake fangs may not penetrate the skin properly for many reasons (thick clothing, or the victim pulling away at the last moment). Snakes rarely inject a full dose of the venom anyway!
If bitten, don’t panic. Anti-venoms are available. If such medicine is not available, avoid using the traditional methods: applying tourniquets and sucking out poison. Instead, concentrate on keeping the patient calm and still. This is very important, as excitement and movement accelerates the spread of venom.
Wrap the bitten limb tightly, as you would for a sprained ankle. Start at the bite, work your way down to the fingers or toes, and then back up to the armpit or groin. Finally, attach a splint to immobilise the limb. This has the effect of localising the venom and slowing its spread.
Then seek medical help, if possible with the dead snake for identification purposes. Don't attempt to catch it if there is even a remote chance of someone else being bitten!!
In an ideal situation, the patient should not be moved, but this may not be possible if you are a long way from assistance. In every situation, seek medical advice as quickly as possible, and do not leave the patient unattended (in some situations patients need assistance breathing, so artificial respiration techniques are useful).
Lizards
Lizards
The Australian outback is home to many interesting species of Lizards, from giants to tiny geckoes. Unable to generate their own heat, they need to lie in the sun to get their blood to the desired temperature for hunting and so forth. For this reason, they are often situated on the roads.
An unusual lizard is the ‘thorny devil’, or ‘mountain devil’. This species is found on the sandy plains of the western arid zone. It is brightly coloured, and has an almost indescribably ferocious appearance thanks to its armour-plated coat of horns and spikes. However, it's quite harmless to humans, as it lives on a diet consisting entirely of tiny black ants.
Ants
Ants
Australia has by far the world's largest number and richest diversity of ant species. Scientists come from all over the world to study them.
These do not include white ants, which are otherwise known as ‘termites’ and have no relation to West Australian ant species. Termite mounds {each mound is the upper part of a nest) are often a spectacular feature of the tropical north. One species builds a large tombstone-shaped mound that points north-south, as a means of regulating the temperature within the mound. Another builds an immense pillar-like mound over 6m high.

Flies
Bush flies can be an unbelievable nuisance. They persist in crawling on you, to obtain protein by drinking your sweat and tears; but they're also waiting for you to go to the toilet behind a bush. Flies lay their eggs in fresh animal droppings, which give their larva (maggots) sustenance in order to grow and pupate.
Effective repellents such as aero guard work reasonably well, and fortunately the flies normally disappear at nightfall.
Mosquitoes
Mosquitoes
Mosquitoes can also be a problem; particularly in the warmer tropical and subtropical areas and also in the south west, around Mandurah.
The risk of Malaria is unlikely, but there's a small risk of Ross River Fever. This is a virus with symptoms similar to Glandular Fever (extreme fatigue, sore joints, nausea, flu-like symptoms). Avoid bites by covering bare skin and using insect repellent, insect screens on windows, and mosquito nets on beds.
Spiders
Spiders
Most Australian spiders bite but few are actually poisonous.
The Redback spider, which is a relative of the American black widow, is widespread throughout Australian and is possibly deadly for children but rarely serious for adults. However, bites should not be left without treatment!
For first-aid treatment apply ice to lessen the pain, and go immediately to a medical facility for anti-venom. Pain occurs rapidly, but the venom acts slowly. Serious problems are unlikely in less than three hours.
Scorpions
Scorpions
There are three species of scorpion in Australia, but they're not very venomous compared with overseas varieties. Currently, only one human is recorded to have died as a result of an Australian scorpion sting. Scorpions often shelter in shoes. Always give your shoes a good shake before wearing them, especially when camping.
Box Jellyfish
Box Jellyfish
This is also known as the ‘stinger’ or ‘sea wasp’. They inhabit the coastal waters north of the Tropic of Capricorn, and are prevalent from October to mid May. They are very difficult to spot in the water, and also impossible to dodge or avoid. Its long, sticky tentacles have vicious venom. They kill about one person per year, and cause considerable pain to many others.
If someone is stung, they are likely to collapse shortly after. They may also have distinguishable welts on their body. They may stop breathing, in which case artificial respiration will be required.
Douse the sting extensively with household vinegar (available from first-aid boxes on many beaches, or from nearby residents) which will deactivate the tentacles. They can then be carefully removed with tweezers. It is wise to apply a compression bandage over the affected area to localise the venom, as for a snake bite, and seek medical help as soon as possible.
Introduced Species Found in Australia
Rabbit and Foxes
Soon after foxes and rabbits were introduced to Australia, for the purpose of hunting/sport in the mid-1800s, it became apparent that a dreadful mistake had been made. Both species spread far and wide with remarkable speed, and it wasn't long before they became pests.
Rabbits have had a devastating effect on native plants and animals, particularly in the arid zone; while foxes have depleted numerous species of Australia's smaller marsupials. Rabbits and foxes have yet to establish themselves in the tropical north.
Camels, Goats, Pigs and Horses
Camels, Goats, Pigs and Horses
Another introduced species in Australia is the one humped camel. Australian camels are being exported to the Middle East to improve the local gene pool.
Other introduced feral pests include the pig, goat, donkey, and horse. All of which have multiplied rapidly in the wild through lack of natural enemies. The goats are being harvested extensively in the area around Carnarvon, and many can be seen on or near road verges.
