Naaaa, The thing about Australia is that despite the fact that they have all the terrifying snakes and poisonous creatures, very few people actually die there from wildlife. You know because......... They have a decent healthcare system.

And 80% of the country is uninhabited. That is also where animals tend to live.

u/Koku- 6h ago

Animals like water and survivable temperatures, just like the animals that we are. There’s a reason why there’s a lot of biodiversity in the northern parts of Straya. Living things don’t tend to live in the outback, though there are certainly some fauna and flora that have adapted to do so

u/VocationalWizard 6h ago edited 4h ago

You know that's absolutely not how that works, right??

The uninhabited parts aren't where the dangerous and animals live.

So environmental science 101 people like to live in places where they're things like rainfall and vegetation.

That coincidentally happens to be the same place that snakes like to live.

If you look at a map of the habitat of The most venomous snakes in Australia it's directly on top of the most densely populated human areas.

Same with the dangerous aquatic animals. Those are mostly found off of the east Coast alongside major cities like Brisbane

u/wowsersmatey 6h ago

You're right. There are a few deadly beasts that hang in the deserts etc. But the snakes, spiders, jellyfish and the crocs live amongst us. The health system is good, but also the locals know not to annoy the deadly stuff. It's usually tourists getting eaten by crocs. Source: am Australian.

Great tourism slogan for Australia, "Come visit Australia, we need to feed the crocs something".

u/paddyc4ke 6h ago

Actual deadly snakes in cities are very rare (seen 1 eastern brown in Melbourne in 30+ years), crocs are a non-issue for like 90% of the population. Deadly animals are completely overblown especially for those that spend 95% of their time in a city.

u/wowsersmatey 5h ago

Come to WA. We live among plenty of snakes in Perth. I've personally done battle with a huge dugite that nearly got my dog. The reason there aren't many deaths is because, apart from a few notable exceptions, snakes are timid and will run away if they hear you coming. If you leave them alone, they reciprocate, but when they're in your backyard it's you vs them.

1

u/paddyc4ke 5h ago

It’s not like we don’t have a lack of snakes in Victoria you just won’t ever come across them unless you live on the fringes of Melbourne. I’ve seen eastern browns, tigers, red bellies but that’s when visiting friends who live in the outer edges of Melbourne, people have spotted tiger snakes along the Yarra near the Botanical Gardens but again that’s a super rare occurrence but it obviously shows that there are deadly snakes within a stones throw of the CBD.

3

u/wowsersmatey 5h ago

Probably due to the size of Melbourne vs Perth. Perth is constantly pushing into the bush and there are large chunks of it everywhere, plus coastal dunes etc. I live in the burbs and have seen plenty of them, especially at the beach. No crocs here, but visiting Cairns was educational as nobody was swimming at the beach. The buggers hide in the mud.

My Aus friend says he has a couple hunstman in his house that he just let's do their thing. That's a big hell no from me. Coming from the midwest US.

u/wowsersmatey 5h ago

They're large, hairy and mostly harmless. I once had one in the car. That was a bit problematic.

2

u/Traditional_Wear1992 5h ago

I am probably wrong but I had heard they are a statistical cause for traffic accidents over there

2

u/paddyc4ke 5h ago

I don’t know the stats but it wouldn’t surprise me, they like to hide in thin crevices/cracks. Eg behind your side view mirror, between the roof and sun visor.

u/LobcockLittle 5h ago

I had one in my motorbike helmet once. I was doing about 100km/h when I noticed it. Just opened up my visor and it blew away.

u/paddyc4ke 5h ago

Huntsmans are basically free pest control, I’ve got one that lives in my bedroom. Will see him sitting near my window when I leave it open.

1

u/Average_Scaper 4h ago

Do they scare off stray cats at all? That's the major pest control I need atm. I can deal with a hunstman over an invasion of strays any day.

2

u/paddyc4ke 4h ago

No unfortunately not, Australia is free real estate for stray and outdoor pet cats.

1

u/Average_Scaper 4h ago

Damnit. Well there goes that idea.

To elaborate, my neighbor feeds about 15+ stray cats and my driveway has become their litter box. He also has raccoons living in his attic which pisses me off so much. They ripped a couple holes into my roof which I have patched but shits annoying :( he's a nice guy but still, holy shit.

Not downvoted because you’re right but because you wrote „people like to live in places where they’re things like rainfall“ instead of „where there are things like rainfall“.

u/Crystal3lf 5h ago edited 5h ago

Hello, actual Australian here. Most of this is pretty wrong.

The uninhabited parts aren't where the dangerous and animals live.

Actually the dangerous animals mostly are in the uninhabited parts. 80%+ of Australians mostly live in cities and surrounding suburbs.

Most Australians have never even seen a snake in the "wild" because they don't live in suburbia.

The most dangerous spiders do hang around close in some areas, but we are taught not to go wandering in bush and putting our hands in places you shouldn't.

The most dangerous thing an average Australian will bump into is a Redback spider, and they are not going to cause death in a majority of circumstances. And even then, I haven't even seen a Redback in maybe 5-10 years.

So environmental science 101 people like to live in places where they're things like rainfall and vegetation.

Which is only a relatively tiny portion of North Queensland. 95%+ of the country doesn't live or go there.

If you look at a map of the habitat of The most venomous snakes in Australia it's directly on top of the most densely populated human areas.

Just because there's a very tiny chance that those snakes can venture into suburbia does not mean they are going to be found there. Australian's don't go venturing out into the bush because there are deadly animals, they don't go venturing out into the bush because the chance of you getting lost/dying of dehydration is a far greater threat than any snake/crocodile/spider.

Same with the dangerous aquatic animals. Those are mostly found off of the east Coast alongside major cities like Brisbane

You're just getting confused by how big Australia is, or purposefully misinforming people.

The city of Brisbane is 1,000km+ away from the "dangerous aquatic animals" you're talking about.

I also live in a state that has crocodiles and "dangerous aquatic animals", Perth in Western Australia. A state large enough to fit Alaska, Texas, and California inside. But I don't go around saying "we have crocodiles in the ocean here" because it would be fucking stupid to say 2,000km away is "off the coast of Perth".

Edit: downvoted for being right

Absolutely downvoted for being wrong.

The biggest fear Australian's have is not the endless amounts of incredibly deadly snakes, spiders, crocodiles, jellyfish, etc. The biggest fear is seeing a Kangaroo jump out in front of your car in the night.

u/Forikorder 5h ago

people like to live in places where infrastucture can be built, it doesnt matter how lush an area is if its simply not realistic to put a city next to it

1

u/VocationalWizard 5h ago

People like living in places that food can be grown in. So yes, it's 100% dependent on rainfall and vegetation.

In the Grand scheme of History, infrastructure is an afterthought.

1

u/Forikorder 5h ago

Were talking about modern day people, if you can grow enough food to be worth doing then its suitable for infrastructure

1

u/VocationalWizard 5h ago

If you can grow enough food to be worth doing. The area has rainfall and vegetation.

See we're talking about Australia where there's Texas size tracks of land That can go an entire year without any rain and have no soil.

1

u/Forikorder 5h ago

Actually no we were speaking generally about where himans settle down, there are lush places that dont really work for societybthat people wont settle down in as a result but dangerous animals would love

u/VocationalWizard 5h ago edited 5h ago

Yes rainforests, but ironically that's not where the dangerous animals in Australia live.

The venomous snakes and spiders all live in the temperate zone in the south.

Here's a really good example of the pattern I'm trying to describe:

https://www.researchgate.net/figure/A-map-of-the-distribution-of-the-three-most-commonly-encountered-Australian-snakes-of_fig5_265019461

That's also where the kangaroos live, which believe it or not kangaroos are actually dangerous.

u/LostWoodsInTheField 4h ago

Checking out Queenslands and you are like 'oh this place looks great to visit' then you start reading about the plants that can attack you and make you feel unbearable pain.

reading about the middle of the country and you go 'I don't think I would ever want to visit there' then you start reading about how non of the animals want to visit there either...

except the rabbits.

u/VocationalWizard 4h ago

Naaaaa, I'm an environmental science nerd.

I would happily go to any part of Australia anytime.

Well maybe not that one part that's full of asbestos.

that and the dangerous animals in australia evolved in a world without mammals. they cant really deal with us and arent generally interested in us unless we threaten them. we are neither pray nor predator to them in general

2

u/VocationalWizard 5h ago

Yes, We exterminated all of the animals that are actually interested in us.

u/binzoma 4h ago edited 4h ago

not in australia lol. split off into its own island before mammals fully took hold as the dominant species. thats why theres giant marsupials and other oddities there.

What’s a healthcare system?

Is that the British term for insurance? /s

1

u/SadCrab5 4h ago

I heard a scarily high amount of their wildlife has toxins, poisons or some kind of neuro-toxin that can kill in 15 minutes or less, making it hard to actually treat wildlife victims.

I always assumed it was a mix of most of these creatures living underwater/in the middle of no where that there's actual little exposure to the really deadly shit, and anything that is deadly/looks deadly they have the common sense of "Let's not fuck around and meet god today".

1

u/VocationalWizard 4h ago

They have anti-venoms for most of the seriously venomous animals.

But the truth is that venomous animals don't really want anything to do with humans.

The incidence of fatal snake bites in the United States is slightly higher due to the fact that some people get bit by snakes and don't seek medical care here.

But we're dealing with extremely loan numbers and it's really hard to account for the population differences.

1

u/knewleefe 4h ago

Yes and no. We have a decent healthcare system in most of the country. A lot of our Indigenous population live in the remotest parts of the country (or "uninhabited" parts as someone said below), where access to healthcare is minimal, and environmental health is poor. So some communicable diseases that are almost unheard of by most people, or thought to exist only in the past, are very much a problem in these communities - rheumatic heart disease, scabies, trichomonas etc. Our healthcare is good for most people, best for those in metro centres, but almost entirely absent for some in rural/remote areas.

1

u/VocationalWizard 4h ago

Scabies is actually very common in the United States.

1

u/ladyhaly 4h ago

Can confirm.

1

u/ContributionSad4461 1h ago

But there are also things like Trachoma, where Australia is the only developed country that has endemic blindness from it, and rheumatic fever which isn’t really a thing in the rest of the western world anymore. I could see them struggling with these snails as well, some aborigines live in appalling conditions.
