What took so long to find Australia? If they were colonizing in Indonesia and papua new guinea etc why didn't they just also travel south?

it was only really useful as a prison

Most of Australia is uninhabitable waste

When the British landed in the southeast (Sydney) they realised it's potential for a colony. Dutch and Portuguese explorers only ever really interacted with the Northern and Western coasts of Australia, Inhospitable desert and jungle with spear chucking 60 IQ cavemen.

They knew about it, and did some trading with the natives, but Australia is essentially a shithole and the natives had nothing of value to trade with outsiders. It wasn't until the Europeans arrived that any outsider found any use for the place (as an open-air prison).

It has more arable land than France, Germany and Italy combined, so not really.

Are you stupid?
Most of Australia is uninhabitable, like he said.
God I hate snarky r*dditors

oh sorry user, I'll be sure NOT to do research next time.

In the side facing away from Indonesia and the old world. The side facing colonisers was pretty unpleasant

Good luck trying to navigate unknown waters without nowadays technology. Also, they knew of it but not the overall size and good regions (there weren't that many expeditions just to discover and to map stuff), like the majority of countries in Europe with America 300y earlier.
