A continent entirely within the Southern Hemisphere, about one-fourth smaller than Europe, its utmost length from E. to W. being 2400 m., and breadth 1971; the coast has singularly few inlets, though many and spacious harbours, only one great gulf, Carpentaria, on the N., and one bight, the Great Australian Bight, on the S.; the interior consists of a low desert plateau, depressed in the centre, bordered with ranges of various elevation, between which and the sea is a varying breadth of coast-land; the chief mountain range is in the E., and extends more or less parallel all the way with the E. coast; the rivers are few, and either in flood or dried up, for the climate is very parching, only one river, the Murray, 2345 m. long, of any consequence, while the lakes, which are numerous, are shallow and nearly all salt; the flora is peculiar, the eucalyptus and the acacia the most characteristic, grains, fruits, and edible roots being all imported; the fauna is no less peculiar, including, in the absence of many animals of other countries, the kangaroo, the dingo, and the duck-bill, the useful animals being likewise all imported; of birds, the cassowary and the emu, and smaller ones of great beauty, but songless; minerals abound, both the precious and the useful; the natives are disappearing, the colonists in 1904 numbering close upon 4,000,000; and the territory divided into Victoria, New South Wales, Queensland, S. Australia, and W. Australia, which with Tasmania federated in 1900 and became the Commonwealth.
