This article considers Australian attitudes to immigration and cultural diversity. It argues that Australia and Canada are the most receptive to immigration among western nations. The average of 25 surveys conducted in Australia in the period 1999-2010 finds 52 in support of the current immigration level or in support of an increased intake, 43 in support of reduction, and 5 uncertain. While there can be no definitive measure of the level of strong opposition to cultural diversity, on the basis of a number of surveys conducted over the last 30 years, there are indications that the level is close to 10 of the population, with higher levels within specific demographics. Areas of high immigrant concentration present a complex picture. They are characterised by high levels of identification with Australia, but also lower levels of trust and sense of safety, lower levels of participation and heightened experience of discrimination.
