I haven't been to Australia, but I have seen news about deadly jellyfishes..so maybe those.

The bogan

Those tree-dropper bears.

All of them!

Skippy.

Big spiders that come in the house I heard they are huge !! Snakes if they are poisonous. Sharks to but I dont swim so thats not a worry!

Clubfoot Sue and The Horse from Kelly's bar in Piermont.

On land, snakes. In the water, box jellyfish.

None I would be trying to see a tiger snake, snake that don't hibernate has peaked my interest

The Australian's or Aussies

Spiders and crocodile

dropbears for sure

Tarantulas

A spider

The poisonous brown snake that one poster said she stepped on and got bit by it.

Spiders.

Kangaroos actually have sharp talons that can slash you to ribbons

All of them. I would need a guide to warn me which ones are the bitey or clawing ones. Saw a photo of roo with the hugest claws, he was trying to get in through a patio door.

Snakes

All the poisonous ones

Flying foxes! Saw a pic once where some poor slob walked out of his house and there it was hanging on the porch!

Humans. They've vicious johnnies.

Unless you decide to wonder off into the bush for some stupid reason, you have nothing to worry about. I've only seen maybe 5 snakes in 40 years. It's simple, don't swim in beaches that have warning signs about marine dangers.

All of them, they all want to kill you.

Especially the Koalas.

Fkin all of them

When I was there I seem to recall that what we mostly had to keep a lookout for was spiders: redbacks and white-tips (I think it was white-tip it was called) specifically.
