Reply to comment by Apprehensive_Age_384 in How and when did dingos arrive in Australia? by [deleted]

The islands above Australia (Papua New Guinea, Indonesia, etc.) were all connected to Australia recently enough that humans and dogs could just walk there.

Indians may have arrived 4000 years ago but other people arrived WAY before that. At the very minimum 50,000 years ago, but that's just the oldest we know about, so probably much longer than that.

Genetic studies show that Dingos arrived around 10,000 years ago, so a long time after humans.

Sumatra and Australia have indeed never been connected since before the Ice Age. Sumatra is part of Sunda Shelf and Australia is part of Sahul Shelf. As part of Sahul Shelf however, Australia and the island of New Guinea was connected. Part of New Guinea today is territory of Indonesia.

New Guinea was not connected to the mainland, so you couldn’t walk to Australia (or New Guinea)
