Australia, forming as it does a vast island continent in the Southern world, lies to some extent within the tropical range, for the Tropic of Capricorn traverses its northern part. At present, however, its most densely populated portion lies just outside the tropics, and it is this semi-tropical part of Australia with which we have mostly to do.
