Australasia
'Australasia' is a term variably used to describe a
region of
Oceania:
Australia,
New Zealand, and neighbouring
islands in the
Pacific Ocean. The term was coined by
Charles de Brosses in ''Histoire des navigations aux terres australes'' (
1756). He derived it from the
Latin for "south of
Asia" and differentiated the area from
Polynesia (to the east) and the southeast Pacific (''
Magellanica''). It is also distinct from
Micronesia (to the northeast).
Physical geography
Physiographically, Australasia includes the Australian continent (along with the Australian island-state of
Tasmania), New Zealand, and
Melanesia:
New Guinea and neighbouring islands north and east of Australia in the Pacific Ocean. The designation is sometimes applied to all the lands and islands of the Pacific Ocean lying between the
equator and
latitude 47° south.
Most of Australia lies on the southern portion of the
Indo-Australian Plate, flanked by the
Indian Ocean to the west and the
Southern Ocean to the south. Peripheral territories lie on the
Eurasian Plate to the northwest, the
Philippine Plate to the north, and in the Pacific Ocean – including numerous
marginal seas – atop the
Pacific Plate to the north and east.
Human geography
Geopolitically, Australasia is sometimes used as a term for Australia and New Zealand together, in the absence of another word limited to those two countries. There are many organizations whose names are prefixed with "(Royal) Australasian Society" that are limited to just Australia and New Zealand.

Australasian Olympic Flag
In the past, Australasia has been used as a name for combined Australia/New Zealand
sporting teams. Examples include
tennis between
1905 and
1913, when Australia and New Zealand combined its best players to compete in the
Davis Cup international tournament (and won it in 1907, 1908, 1909 and 1911), and at the
Olympic Games of
1908 and
1912.
In speculative fiction or
counterfactual historical analysis, it is used to describe an
alternate history Australia and New Zealand which agreed to political union at Australian federation in
1901, rather than seeking divergent
British Empire Dominion status in 1901 and
1907 respectively.
Anthropologists, although disagreeing on details, generally support theories that call for a
Southeastern Asian origin of indigenous island peoples in Australasia and neighboring
subregions.
Ecological geography
From an
ecological perspective the
Australasia ecozone is a distinct region with a common evolutionary history and a great many unique
flora and
fauna. In this context, Australasia is limited to Australia, New Guinea, and neighbouring islands, including the
Indonesian islands from
Lombok and
Sulawesi eastward. The biological dividing line from
Asia is the
Wallace line –
Borneo and
Bali lie on the western, Asian side.
New Zealand comprises another ecological zone altogether, as it had been isolated from the rest of the world, including the rest of Australasia, for even longer.
