In 2019-20, the State partnered with the Gunditj Mirring Traditional Owners Aboriginal Corporation (GMTOAC) to provide high-resolution mapping, including high-density LiDAR, of the UNESCO World Heritage-listed Budj Bim region in south-western Victoria.

Budj Bim contains one of the world's oldest and most extensive aquaculture systems. The data was used by the Traditional Owners to discover undocumented areas of fish traps and remnant stone huts and will continue to be used for many land management purposes to protect this important Aboriginal Heritage site. The GMTOAC owns this data and any use requires their permission.
