Title: Australia


1
Australia Oceania
2
  • Region dominated by Australia New Zealand
  • Most residents live in urban settlements near the
    coast
  • They share a common European heritage close
    cultural links with Britain
  • Remainder of the region is dominated by island
    chains that can be divided into three regions

  • Melanesia
  • Dark Islands
  • Located on the western edge of Oceania and
    largely inhabited by dark skinned people
  • Includes New Guinea, Solomon Islands, Vanuatu,
    Fiji
  • Polynesia
  • Many Islands
  • Groups of smaller islands located in the south
    central Pacific
  • Includes French Tahiti, Society Islands, Hawaii,
    Tonga, Tuvalu, Samoa as well as the Maori
    people of New Zealand
  • Micronesia
  • Small Islands
  • Located north of Melanesia and west of Polynesia
  • Includes Nauru, the Marshall Islands, and Guam,

  • Characteristics that Unite Australia Oceania
  • The unique physical setting has historically
    isolated it from the rest of the world
  • The region reveals a fascinating set of responses
    between indigenous people and varied European
    cultures
  • The region is united by its youthful political
    geography

6
Physical Environment
  • Because of geographic isolation, unique plants
    and animals have evolved
  • This is a latitudinally diverse region 20 N
    45 S
  • There is also much variation atlitudinally

7
Physical Environment
  • Australia
  • Three major landforms from west to east
  • Western plateau occupies more than half of the
    continent, 1,000-1,800 ft. in height
  • Lowland basin region stretches 1,000 mi. north
    to south most is a flat, featureless plain with
    little water
  • Forested and mountainous region Great Dividing
    Range runs from the Cape York Peninsula to
    Victoria it is an old mountain range with few
    peaks above 5,000 ft.
  • The range has historically been an impediment to
    interaction between the coast and the interior

8
Physical Environment
  • Australia
  • There are four distinctive climates found in
    Australia
  • Tropical wet dry in the north
  • Hot and dry interior
  • Temperate east coast with ample rainfall
  • Mediterranean southwest coast

Physical Environment
  • Australian Animals
  • Because of their isolation, the animals of
    Australia have evolved in unique ways
  • Marsupials (animals that carry their young in
    pouches) were able to adapt to the natural
    environment

Physical Environment
  • Australian Animals
  • Because of their isolation, the animals of
    Australia have evolved in unique ways
  • Marsupials (animals that carry their young in
    pouches) were able to adapt to the natural
    environment
  • The introduction of exotic (non-native) species
    can be particularly detrimental to the Australian
    environment
  • The introduction of rabbits is one of the most
    well known examples of the introduction of an
    exotic species
  • Rabbits were introduced by English settlers for
    sport hunting
  • There is no natural predator for the rabbit in
    Australia coupled with the breeding capacity of
    rabbits quickly led to problems
  • The government mounted an eradication effort that
    utilized fences, snares, guns, dogs, fires and
    numerous other means but it has had limited
    success

15
Physical Environment
  • New Zealand
  • New Zealand is also home to a number of unique
    species
  • 85 of trees and plants are found nowhere else on
    earth
  • The country consists of two main islands
  • North Island
  • Subtropical and relatively wet climate
  • South Island
  • Distinctly colder than the North Island
    becoming more severe as one moves south

16
Physical Environment
  • Oceania
  • Consists of thousands of islands that are
    influenced by the surrounding maritime
    environment
  • The formation of islands varies throughout the
    region
  • The larger islands of Melanesia New Zealand are
    composed of fragmented continental rock
  • The majority of the islands originated from
    volcanic activity without any connection to other
    geological processes
  • The formation of islands in Oceania is a process
    that takes thousands of years
  • Larger, more active volcanic islands form High
    Islands usually surrounded by coral reefs
  • Over time (hundreds of thousands of years), the
    volcano is steadily worn away via erosion,
    leaving low peaks surrounded by a coral reef

17
Bora Bora, French Polynesia
18
Bora Bora
19
Physical Environment
  • Oceania
  • Eventually, the entire volcano erodes away,
    leaving a coral reef surrounding a shallow lagoon
  • The reefs tend to remain because they are made of
    living material
  • Often an atoll will form - the combination of
    narrow sandy islands, barrier coral reefs, and
    shallow central lagoons

The Indigenous Population
  • The islands of New Guinea and Australia were the
    first in the region to be inhabited by people
  • People first began to migrate 40,000 years ago
  • Smaller, remote islands were unreachable because
    the people did not possess sophisticated
    watercraft
  • More distant lands in Melanesia were reached
    3,500 years ago from there islands in Polynesia
    Micronesia were discovered
  • By AD 1000, people had reached the Hawaiian
    Islands, New Zealand Easter Island

22
European Colonization
  • New Zealand was discovered by Dutch explorer Abel
    Tasman in 1642
  • Between 1768 and 1780, British captain James Cook
    surveyed the Australian and New Zealand
    coastlines
  • Australia
  • By the 1780s, the British needed a penal colony
    in which they could exile their convicts
  • Southeastern Australia was chosen as the site of
    the new colony
  • In 1788, 750 convicts were deposited at Botany
    Bay (near present day city of Sidney)
  • Additional shipments of convicts, as well as free
    settlers soon followed the free settlers soon
    outnumbered the convicts

23
European Colonization
  • Australia
  • Settlers soon migrated inland and up the coast,
    founding new cities along the way
  • Many people were initially attracted to Australia
    for its livestock raising possibilities and gold
    (gold rush in the 1850s)
  • As they migrated inland, the settlers came into
    contact, and later conflict with the aboriginal
    people
  • In most cases, the Aborigines were pushed out of
    the way when British settlers came into an area
    (In the case of Tasmania, Aborigines were hunted
    down and killed)
  • New Zealand
  • Whalers and sealers arrived in New Zealand
    shortly before 1800
  • More permanent agricultural based settlement
    began after 1840

24
European Colonization
  • New Zealand
  • As more settlers arrived, tensions between them
    and the native Maori people
  • In 1845, the Maori resisted British rule, thus
    began the Maori Wars which were fought until 1870
  • The British prevailed and the Maori lost most of
    their land
  • Elsewhere in Oceania, European settlement was
    much less significant. European powers
    eventually gained control of the region, but few
    migrated there

25
Aboriginal People of Australia
  • The Aboriginal people existed in a hunting
    gathering society prior to European contact
  • The population remained quite low (est. 300,000
    at the time of contact)
  • Aborigines were often viewed as sub-human by the
    Europeans because they had no centralized
    political organization and they did not practice
    agriculture
  • There were no treaties signed and no concessions
    made, they were simply run off their land
  • With colonization, the Aboriginal population was
    forced into the interior particularly in
    northern and western Australia

26
Aboriginal People of Australia
  • Today approximately 2 of the Australian
    population is classified as Aboriginal
  • The majority of them (70) live in urban areas
    and have been assimilated into Australian society
  • Many of them practice Christianity and few speak
    their native language
  • Very few live in the Outback and practice their
    traditional hunting and gathering way of life
  • Despite this, there is a growing movement among
    the Aborigines to preserve their traditional way
    of life

Diversity of the Australian Population
  • Over 70 of the Australian population reflects
    British or Irish heritage
  • These groups dominated migration in the
    nineteenth and early twentieth centuries
  • Additional European migration (Italians, Greeks,
    Germans) added to the diversity of the European
    population
  • Historically, non-white migration into Australia
    has been limited by the White Australia Policy in
    which governmental guidelines promoted European
    and North American immigration
  • Recently, this trend has been reversed, more
    diverse people have been allowed to emigrate into
    Australia
  • Since 1970, people have been chosen based upon
    their educational background and potential for
    succeeding economically
  • There is a growing number of immigrants from
    China, India, Malaysia, the Philippines, Vietnam
    Yugoslavia

29
Diversity of the Australian Population
  • The immigrant population has grown dramatically
    in recent years
  • Today, 22 of the population is foreign born
  • By the late 1990s, almost half (40) of
    immigrants were from Asia
  • This recent influx of migrants has changed
    Australian Society
  • Some of the countrys fastest growing religions
    are Islam, Hinduism, Buddhism
  • 2.5 million (of a population of 18 million) speak
    a foreign language
  • There are some who are not in favor of this move
    towards a more multi-cultural society
  • A small, yet vocal minority would like more the
    restrictive immigration policies to be reinstated

30
The Maori of New Zealand
  • The Maori are more numerous and visible than the
    Aborigines in Australia
  • After the Maori Wars, the Maori began to rebuild
    their society
  • Today they account for more than 10 of New
    Zealands 3,8 million people
  • They are concentrated in the North Island
  • Although they are moving into urban areas, they
    are still committed to preserving their religion
    and traditional art
