What? Australia before New Guinea? How did man get to Australia, if not via New Guinea?

Looking at the map, "via New Guinea" seems the only likely route. It there any evidence of what portion of Australia was the first-inhabited?


On reinspection of the little map, the arrow from southeast Asia goes through Borneo and then splits off to Australia and New Guinea. I suppose it could be saying that they were both populated by 40,000 BC. It says 33,000 next to a little arrow that goes from New Guinea into Polynesia and then 1200 next to an arrow going further.

The arrow to Oz goes about right through Darwin, but that's probably not exact. It's just a convenient place to put the arrow.
