The last person that died from a spider bite was in 1979. Snakes and spiders mostly just want to left alone. Crocodiles and marine stingers only exist in the tropics, and Sharks only eat ocean swimmers.
I grew up very close to native bush land on the outskirts of Sydney and have never been 'prey' to another creature while playing in the bush.
Of course, I wouldn't have done that if drop-bears [1] were around though.
There was one this year, actually[1]. Non-fatal bites are more common, but there's no official statistics because it's not a reportable medical emergency.
Folks that live near bushland of any variety know to do the basics like not sticking your fingers into areas you can't see, and not weeding/digging in the garden within the Sydney region with bare hands.

Survivor bias, mate.
(BTH, this requires only one such fatal crash because nobody in Australia has died from a spider bite since 1979).
More seriously, didn't Australia previously have some geological activity? I've heard of lava tubes near Cairns and have visited the Sunshine Coast where I believe there are (dormant?) volcanos?
That's the secret Australians don't want you to know!
Most of our native wildlife is pretty sleepy and shy - there's only a couple of snakes that are aggressive; most run (slither?) away from humans. Apart from that, crocodiles are really only the remaining aggressive land animal, but there's not a lot of overlap between a population map of humans vs crocodiles here.
Dingoes, fair enough, I missed those. They're opportunistic though, and you have to go looking for reports on attacks (apart from the obvious one, which was hard to escape the media frenzy of...). Dingo attacks a but a drop in the ocean compared to other (pet) dog attacks here.
The most dangerous mammal in North America is...Bambi. The U.S. Department of Transportation estimates that white-tailed deer kill around 130 Americans each year simply by causing car accidents. In 1994, these predator deer had a banner year, causing 211 human deaths in car wrecks.
There are about 1.5 million deer/vehicle collisions annually, resulting in 29,000 human injuries and more than $1 billion in insurance claims in addition to the death toll.
And here's Wikipedia on it: https://en.wikipedia.org/wiki/Deer%E2%80%93vehicle_collision... They even kill around 20/year in Germany.

That is an anecdote obviously, not a widespread danger.
