<Li> Newcastle - Maitland </Li> <Li> Canberra - Queanbeyan </Li> <P> Australia, sometimes known in technical contexts by the names Sahul, Australinea or Meganesia, to distinguish it from the country of Australia, is a continent comprising mainland Australia, Tasmania, New Guinea, New Britain, and small neighbouring islands (such as Misool and Waigeo, just to the northeast of Maluku Islands at the edge of its continental shelf). Situated in the geographical region of Oceania, it is the smallest of the seven traditional continents in the English conception . Countries within the continent include Australia, Papua New Guinea and, partially, Indonesia . </P> <P> The continent lies on a continental shelf overlain by shallow seas which divide it into several landmasses--the Arafura Sea and Torres Strait between mainland Australia and New Guinea, and Bass Strait between mainland Australia and Tasmania . When sea levels were lower during the Pleistocene ice age, including the Last Glacial Maximum about 18,000 BC, they were connected by dry land . During the past 10,000 years, rising sea levels overflowed the lowlands and separated the continent into today's low - lying arid to semi-arid mainland and the two mountainous islands of New Guinea and Tasmania . </P>
