"The Digger" was published monthly between 1972 and 1975 and served as a national outlet for many movements within Australia's counterculture with notable contributors—including second-wave feminists Anne Summers and Helen Garner, Californian cartoonist Ron Cobb's observations during a year-long stay in the country, Aboriginal activist Cheryl Buchanan, radical scientist Alan Roberts on global warming—and ongoing coverage of cultural trailblazers such as the Australian Performing Group (aka Pram Factory), and emerging Australian filmmakers.
