The Thought Criminals were an influential and enterprising Australian punk band based in Sydney. They formed in late 1977 and disbanded in late 1981. The "angular, fast and quirky punk rock" of the Thought Criminals "was a fixture in the burgeoning Sydney underground scene." The band's name was derived from the concept of 'thoughtcrimes' (unapproved thoughts) from George Orwell's book, Nineteen Eighty-Four. The Thought Criminals exemplified the do-it-yourself punk ethos of the late 1970s, with which they combined considerable business acumen. The band members formed the Doublethink record label and agency which provided recording and live performance opportunities for other new bands.
