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.
