With immigrant numbers continuing to grow, in 1975 the federal parliament passed the Racial Discrimination Act, enshrining in law the ideal that all Australians should be treated equally and not discriminated against on the basis of skin color, ethnicity, or religious faith. This act was the final nail in the coffin of the White Australia policy.
另一方面，隨著移民日增且來源日趨多元，1975 年，澳洲政府終於公佈「反種族歧視法」，保證全體澳大利亞人不分種族、膚色與信仰，一律平等，此舉也等於在法律上埋葬了「白澳政策」。
