Malcolm Fraser opened the door to Vietnamese refugees in the late 1970s and championed a larger Australia through immigration. Here, in an extract from the new Fraser biography, he remembers the birth of multiculturalism.

Fraser had since his first days in politics advocated immigration as a means of boosting Australia’s population. In his earliest speeches and radio addresses he said that he hoped to see Australia reach a population of 25 million in his lifetime -- an ambition he is likely to fulfil. As a minister in the Gorton government he had become the first federal politician to use the word "multiculturalism".
