澳大利亚是一个移民国家。战后移民在澳大利亚移民史上占据非常重要的地位。战后移民的原因是多方面的。加强防务安全是战后初期澳大利亚大规模移民的首要原因。当防务安全退居其次时,战后国家重建、经济发展乃至社会建设就成为移民的主要考虑。 Australia is an immigrant country. Post-war immigrants occupy a very important position in the history of Australian immigrants. There are many reasons for the post-war immigration. Strengthening defense security is the primary reason for mass immigration in Australia in the early postwar period. When the defense and safety are relegated to the second place, post-war reconstruction of the country, economic development and even social construction have become the main considerations for immigrants.
