Located south of the equator, Australia, the Island Continent, is bounded by the Indian Ocean to the west and Pacific Ocean in the east.
It occupies cool temperate to tropical climates from 10° south to 43° south latitude and from 112° east to 153° east longitude, to the south of the countries of Indonesia and Papua New Guinea, and west of New Zealand.
From the Coral Sea and South Pacific Ocean in the north, ocean currents sweep south along the east coast from the Great Barrier Reef, into Tasman Sea, past the island of Tasmania and into the Roaring Forties.
In the southwest, the Great Southern Ocean receives the barest hint of the warm currents swept into the Indian Ocean from the equatorial waters of the Timor and Arafura Seas, which separates the northern Australian mainland from Papua New Guinea and Indonesia.
