From 1974 until 1979 he lived in
Papua New Guinea, which was in the process of decolonisation. He worked for the newly independent government, teaching documentary filmmaking skills to Papua New Guineans. His first film,
Yumi Yet - Independence for Papua New Guinea, was completed in 1976. O'Rourke's film
Half Life: A Parable for the Nuclear Age was screened at a
Leicester Square cinema in London in 1986. Controversy sometimes surrounded O'Rourke's interactions with, and depiction of, the individuals who were subjects of his documentaries, such as
The Good Woman of Bangkok (released in 1991), which concerned a sex worker in Thailand and
Cunnamulla (2000), which was made up mostly of monologues by residents of the
Queensland town of the same name, discussing everyday life. In 2007, O'Rourke was awarded damages by the
Australian Capital Territory Supreme Court for defamation. The action followed the reporting of comments accusing O'Rourke of unscrupulous conduct during the filming of
Cunnamulla. The awards were made against an Aboriginal rights activist and Nationwide News Pty Ltd (a subsidiary of
News Corporation), as the parent company of the Sydney
Daily Telegraph and
The Australian. ==Later life and death==
