The BLF fought successful campaigns which became known as the
green bans against development projects which it viewed as harmful to the
built and
natural environment of Sydney and Melbourne. These campaigns included blocking plans to redevelop
The Rocks area, Kelly's Bush in
Hunters Hill,
Centennial Park, the
City Baths,
Flinders Street station, Victoria Street in
Potts Point, and the
Hotel Windsor. The green bans are now commonly recognised as directly responsible for saving areas of Sydney and Melbourne with substantial heritage value.
Victoria Hall in
Fremantle,
Western Australia was also saved from demolition by a green ban, in 1974. They also took up other causes, such as Aboriginal rights, anti-war campaigns and support for pensioners. In NSW the union engaged in 'pink bans', halting work at universities to support gay students facing expulsion and discrimination. The BLF had a long-standing programme on radio station
3CR, "The Concrete Gang", which is now presented by the
Construction, Forestry, Mining and Energy Union. One of the original announcers for the BLF was
John Cummins.
Work-ins The BLF also helped organise a number of "work-ins" across Australia, where workers would take over a site for a few weeks and run it under workers' control. Some notable examples include: • 1972:
Sydney Opera House • 1974:
