​Liddell Coal and its immediate surrounds are the subject of regular archaeological investigations, both surface and subsurface.

The survey areas for these projects are selected based on the location of proposed mining disturbance areas for which previous surveys have not been conducted and may adjoin previous study areas. No archaeological sites are disturbed without the appropriate permits issued by the Department of Environment and Conservation following consultation with the Aboriginal community.

Meetings are held with local Aboriginal groups at least every 12 months. The purpose of these meetings is to keep the Aboriginal community informed of the progress of mining operations, discuss any upcoming projects, and to seek feedback from the Aboriginal community on archaeological and operational issues.
