The CEO for Ports Victoria, Brendan Webb, was recently interviewed on ABC News radio and provided the following update about the impending move of the Spirit of Tasmania.
The enhancements to Corio Quay (north Geelong) are on track to be completed this winter and it is expected the Spirit will start to operate from that location by October 2022. This will mark the end of traffic queues for the ferry in Port Melbourne and significant reduction in truck movement through Bay and Graham Streets.
The new replacements to the existing two Spirit of Tasmania ferries are being constructed in Finland and are currently expected to start service between Corio Quay and Devonport in late 2023. The new ferries will each have a capacity of 1800 passengers vs existing Spirit capacity of 1400.
