Great Ocean Road and Inland Routes - landslip works

We’re stabilising roadsides and minimising the risk of landslips at four key locations on the Great Ocean Road and inland routes network, in Victoria’s South West.

Project status:

Underway

Overview

We’re delivering landslip geotechnical works to protect the longevity of the natural roadside landscape and improve safety for all road users at:

Cobden-Port Campbell Road, approximately 8kms south of Cobden, between Dingleys Road and Digneys Bridge Road
Colac-Lavers Hill Road, approximately 4kms north of Ferguson, between Brockmans Road and Murchisons Road
Timboon-Port Campbell Road, approximately 8kms south-east of Timboon, between Wild Dog Road and Cobden-Port Campbell Road
Great Ocean Road, between Kennett River and Grey River

The Victorian Government has invested $255 million in the Great Ocean Road and its inland routes. This includes $115 million to upgrade inland routes between the Great Ocean Road and the Princes Highway, which are vital connections for tourism, freight and local communities.

Update – September 2026

Works on the Great Ocean Road were completed in August, 2026. Construction at the Cobden-Port Campbell Road, Colac-Lavers Hill Road and Timboon-Port Campbell Road sites are expected to be completed in late 2026.

Timboon-Port Campbell Road closure – from 16 September 2026

From Wednesday, 16 September 2026, Timboon-Port Campbell Road will close near the intersection of Cobden-Port Campbell Road for approximately three weeks. A detour will be in place via New Cooriemungle Road and Cobden-Port Campbell Road.

The road closure is required to complete a complex portion of the works safely.

Please follow all signage and allow additional travel time.

Disruptions at other landslip sites will continue as outlined below.
