The dingo must have already been at least somewhat domesticated when it was brought to Australia (4-12,000 years ago, later than the first humans) because nobody is going to cross a 50 km strait in a canoe/raft/boat with a wild dog.

Presumably they went wild again afterwards, but it must be easier to re-domesticate a dog that was domesticated a few thousand years ago than to domesticate an entirely new species.

Good point, I hadn't thought of that.

Was it brought there or did it raft there by itself ?

(that's not a joke, plenty of animals have been involuntarily moved between continents on makeshift rafts)

The dingo is a fascinating creature.

Floating there on its own seems pretty unlikely, since Australia didn't acquire any other wildlife from South-East Asia. At the time of British settlement the dingo was the only placental mammal on the continent, apart from bats and humans.
