History of Immigration in Australia and actual situation
Since 1945, over 6 million people have come to Australia as new settlers. They have had a marked influence on all aspects of that society. In the 50 years of planned post-war migration, Australia has seen:
5.9 million migrants arrive comprising about 3.1 million males and 2.8 million females; more than 600,000 people arrive under humanitarian programs, initially as displaced persons and more recently as refugees; and a population rise from about 7 million to over 19 million.

The trigger for a large-scale migration program was the end of World War II. Agreements were reached with Britain, some European countries and with the International Refugee Organisation to encourage migration, including displaced people from war-torn Europe. About one million migrants arrived in each of the five decades following 1950: Today, nearly one in four of Australia's 19 million people was born overseas. For the past three financial years New Zealand displaced the United Kingdom as the largest source birthplace of migrants.

Today's migration program recognises that business globalisation has resulted in a major flow of people who often do not intend to stay in Australia permanently. Australia's population increased steadily by one to two per cent a year during the past 10 years and natural increase - the excess of births over deaths - has contributed more to the population growth than net overseas migration (NOM), that is, permanent and long-term temporary arrivals less permanent and long-term temporary departures.
The Australian preliminary estimated resident population was 19.6 million at 31 December 2001

Australia has a non-discriminatory immigration policy, which means that anyone from any country can apply to migrate, regardless of their ethnic origin, gender, race or religion.

Migration to Australia is dependent on the applicant's ability to meet the migration criteria of the day, which are established to meet Australia's national interest and needs. There are different criteria for the various visa categories, and all migrants must meet Australia's rules on health and character.
Migrants are chosen from two broad categories - Skill Stream and Family Stream - while the Humanitarian Program caters for those people from refugee or refugee-like situations in urgent need of resettlement.
