In 2019-20, the entire Great Ocean Road was mapped using both aerial and mobile LiDAR (ALS/MLS), as well as high-resolution aerial imagery.

This project enabled Surveyor-General Victoria (SGV) to improve the mapping of properties and parcels along the road and deliver a major priority of the Great Ocean Road Action Plan. It helped establish the Great Ocean Road Coast and Parks Authority (GORCAPA) and to protect and manage coastal Crown land along the Great Ocean Road.
