Australia (also called Australia-New Guinea, Sahul, Meganesia, Greater Australia or Australinea) is a continent comprising (in order of size) the Australian mainland, New Guinea, Tasmania, and intervening islands, all of which sit on the same continental shelf. These landmasses are separated by seas overlying the continental shelf — the Arafura Sea and Torres Strait between 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 years ago, the lands formed a single, continuous landmass. During the past ten thousand years rising sea levels overflowed the lowlands and separated the continent into today's low-lying semi-arid mainland and the two mountainous islands of New Guinea and Tasmania.
Geologically the continent extends to the edge of the continental shelf, so the now-separate lands can still be considered a continent.[1] Due to the spread of flora and fauna across the single Pleistocene landmass, the separate lands have a related biota.
New Zealand is not on the same continental shelf and so is not part of the continent of Australia but is part of the wider region known as Australasia.

Australia is both an island and a continent so it is not part of any other continent.
Australasia is just a general term for that area of the Pacific.
Papua New Guinea is not part of Australia. Tasmania is one of the states like Victoria, New South Wales, Queensland and Western Australia.

They are just different names/terms referring to the same thing.
When talking about continents, Oceania, Australasia, and sometimes Australia are all used to mean the countries in the Pacific region surrounding Australia.
When one talks about continents, for instance, New Zealand and Australia never belong to different continents.

The names are interchangeable. The correct terminology is Australia -- as it was when I went to school it was called Australia. Calling it Oceania allows for it to include the islands incorporated within the area that Australia "owns"; as well as other island nations within the Pacific, Indian, and Southern oceans including the Philippines, New Zealand, Papua/New Guinea etc. The names Oceania or Australasia are sometimes used in place of Australia. For example, the Atlas of Canada names Oceania, as does the model taught in Latin America and Iberia.

according to United Nations geoscheme, the world is divided into 5 macro-geographical regions which are arranged according to continents. according to the scheme, Australia is member of Oceania continent.
the Western European and Others Group (WEOG) is one of several unofficial regional voting blocs within the United Nations. Australia is representative of Oceania regional grouping.
Australia was representative of Oceania football Confederation (OFC) in FIFA Football World Cup 2006. OFC is one of six continental confederations of international football. one of founding members of OFC was Football Federation Australia.
from the facts of above, there is no doubt that Australia is part of Oceania continent. if australia is not part of Oceania continent, how Australia can be voice of Oceania?
