Although road signs indicated the coastal road runs between Allansford and Torquay, the inclusion of Glenelg Shire brings the potential spin-off from the world-famous Twelve Apostles near Port Campbell.

Portland has been highlighted for the blue whales which frequent the coastline from November to May — “a truly amazing experience” according to the Great Southern Touring Route website.

It is hoped it will boost tourism to nearby Portland district bays and coastline to the South Australian border.

Glenelg Shire Council mayor John Northcott said Portland often missed benefits of high tourist traffic travelling the official Great Ocean Road because of its location.

“Tourism routes and infrastructure should extend tourism opportunities throughout the region and link attractions in and beyond the region, including west to Penola/Coonawarra, north to the northern Grampians, and east to Ballarat, Greater Geelong and Melbourne,” he said.
