In the video Sharing a Collection David Lovett (Gunditj Mirring) explains how this grinding stone has multiple uses: one side to grind seeds and make flour, the other to make fire.
This type of grinding stone is known as a doughnut grinding slab.
The Dunkeld & District Historical Museum and members of the local Aboriginal communities have worked together to research and register the Dunkeld Aboriginal Object Collection. The partnership has improved interpretation and presentation of Aboriginal perspectives of the district’s cultural heritage; ensured that Dunkeld Museum meets its legal obligations under the Aboriginal Heritage Act 2006; and improved access to the collection for Aboriginal people and the general community.
