Multicultural Arc describes and analyses a half-century of multicultural action and policy in Australia, as the country changed from being 99.5% European to one of the most diverse societies in the world. Through examinations of the changes introduced by successive governments, readers follow the twists and turns of ideology and popular attitudes. From the “invention” of Australian multiculturalism through to attacks on its very existence, the affirmation of Australia’s multicultural future now depends on addressing systemic racism and continuing inequalities. Five key themes include the place of First Nations in a multicultural society, the problems of racism, the challenges of communication and representation, the shredding of research capacity, and the creation of best fit institutions. Key words for the future are recognition, research and representation. Multicultural Arc is published by Sydney Multicultural Community Services.
