In 2004 the Victorian Government launched the Port Phillip Channel Deepening Project to deepen the existing shipping channels and the lower Yarra to accommodate deeper draft vessels. The lower Yarra sediments were identified as likely to be contaminated with toxic chemicals and heavy metals, and were to be contained within a sealed berm clear of the shipping channels south of the Yarra entrance. The vessel chosen for the dredging is the Queen of the Netherlands. 52 environmental groups, recreational fishing groups, and divers' groups formed the "Blue Wedges" group to oppose the proposed channel deepening and dredging with organised protests carried out, culminating in the group taking action in the Federal Court in January 2008 against the Commonwealth to stop it signing off on the project. On 15 January 2008 it was announced that their appeal was dismissed, with dredging starting soon after. The government announced the completion of works in November 2009, ahead of schedule and $200 million under budget.
