Through the 1970s and 1980s the party continued to decline, despite adopting Eurocommunism and democratising its internal structures so that it became a looser radical party rather than a classic Marxist-Leninist one. The CPA conducted campaigns against nuclear weapons and the extraction of uranium, and supported the demands of indigenous peoples in Australia and abroad, especially in Papua New Guinea. It thus militated for the abolition of legislation judged repressive regarding indigenous people, for equal pay and for land rights. Its members helped Aboriginal workers in Pilbara lead the longest industrial strike ever in Australia. Internationally, the Communist Party of Australia was close to the Revolutionary Front for the Independence of East Timor (Fretilin) who resisted the Indonesian occupation in the 1970s and 1980s. By 1990 its membership had declined to less than a thousand.
