Builders Labourers Federation (Australia) green bans campaign (1971–1975)
In the late 1960s and early 1970s, major redevelopment plans threatened older neighborhoods, parks, and working-class housing in Sydney. Local residents formed action groups to oppose demolitions and to demand a say in planning decisions. These campaigns set the stage for unions and community groups to work together in a new way.
A small group of local women in Hunters Hill organized to stop development at Kelly’s Bush, one of the last remaining bushland areas on the Parramatta River foreshore. After petitions and approaches to politicians failed, they looked for new allies. Their campaign became a model for how resident groups would later request union support.
Residents in The Rocks opposed plans that would have demolished much of the historic area for large tower blocks. The NSW BLF backed the residents with a green ban, helping to halt demolition and force changes to the redevelopment approach. This helped establish heritage conservation as a central goal of the green bans campaign.
After a large public meeting showed strong local backing, the New South Wales Builders Labourers’ Federation (NSW BLF) voted to refuse work at Kelly’s Bush. This action—later widely described as the world’s first “green ban”—linked construction workers’ labor power to environmental protection. The Kelly’s Bush ban became the starting point for a wider campaign across Sydney.
A proposed car park linked to the Sydney Opera House would have taken space from the Royal Botanic Gardens. The NSW BLF supported efforts to protect the gardens by refusing work, helping shift the conversation toward preserving public green space in the city center. This episode showed that green bans could target major, high-profile public projects—not only private developments.
Woolloomooloo residents formed an action group to resist plans that would have replaced housing with large commercial development. The NSW BLF placed a green ban in support, aiming to protect both the community and affordable inner-city housing. The ban became one of the best-known examples of green bans defending working-class neighborhoods.
In Kings Cross, residents and supporters resisted redevelopment plans that threatened to remove existing terrace housing. The NSW BLF backed the community, and the struggle intensified as pressure on remaining residents increased. Victoria Street became a defining campaign because it combined housing rights, heritage issues, and confrontations over who controlled the city’s future.
As word spread, more resident groups sought bans to protect housing, parks, and historic buildings. The NSW BLF emphasized that bans were requested by community groups and supported through democratic union meetings, rather than imposed by union leaders alone. By this point, green bans were becoming a recognized part of Sydney’s political and planning debates.
As residents and supporters tried to keep buildings occupied, police cleared squatters from multiple houses on Victoria Street. The evictions demonstrated the limits of industrial bans alone when faced with coordinated legal and police action. The conflict also increased public attention on the human impact of redevelopment pressures.
In 1974, the BLF’s federal registration was cancelled, removing key legal standing within Australia’s industrial relations system. Deregistration increased pressure on the union and changed the internal power balance between the NSW branch and the federal leadership. This legal step became a major turning point that weakened the conditions that had allowed green bans to spread.
As conflict intensified, the BLF’s federal leadership intervened in NSW branch affairs during 1974–1975. This intervention undermined the NSW branch’s democratic decision-making and led to bans being lifted or broken at several sites. The green bans campaign began to unravel as union control shifted away from leaders who supported community-requested bans.
By March 1975, the NSW BLF leadership most closely associated with the green bans—often identified with Jack Mundey, Bob Pringle, and Joe Owens—was removed through federal action. With new leadership and rising economic pressure, the union stopped pursuing green bans as a central strategy. The 1971–1975 period ended with the movement’s influence remaining in saved sites and in later “red-green” labor-environment alliances.
