How come Australians were sheltered for so long from other civilizations

Yep. Too much ocean and Australia itself is a massive place which was sparsely populated

I wonder if purebred Aborigines can even get colds from white people?

High population density means development, development increases population density.

Nice.

So did these indians actually manage to return to reveal their findings or is it implied that they stayed in australia?

Apparently, this was the earliest contact australians ever had with other cultures, but it is still pretty small. They still seem pretty sheltered to me.

Keep in mind that abos aren't a nation. We just treat them like one for the sake of convenience. An abo from the west coast of Australia is only similar to one from Tasmania in that they're both dark and kill shit with sticks for a living. Abos had contact with other abo cultures so they were only sheltered from the point of view of a culture that was sailing across the entire world.

They had contact with the muslim traders to the north, though.

The Dingo only turned up in Australia in historical times and is closely related to wild dogs in SE Asia, so there must have been some contact.

Please explain further.
I'm genuinely interested in that. At least, post some source I can read about.

They weren't. There was extensive interaction and trade in northern australia and asian sailors for centuries.

Got something to back that up? I know there was probably some trading as early as 1500 or 1600, but there's not much evidence about the rest.
