Opponents of the east-west link have pledged to move their protests to the companies short-listed to build the multibillion-dollar project.

About 300 residents gathered for an anti-tunnel rally held in Fitzroy on Sunday, the latest in a series of community-led protests against the controversial proposed tunnel.

Socialist and Yarra councillor Stephen Jolly said protests so far had been focused on test drilling sites but would soon shift to targeting companies with prospective ties to the project.

”We’re going to be putting a blowtorch to their backsides in the next few weeks. And anyone that wants to put their grubby little hands on this project will be targeted,” he said.
