Melbourne Deed, also known as the Batman Treaty, 1835.
Batman acquired land in the Melbourne area from the local Aboriginal people in exchange for blankets, tomahawks, knives, scissors, looking glasses, handkerchiefs, flour and shirts. Possum skin cloaks, baskets and weapons were presented to Batman in return, so the exchange may have been viewed as a form of tanderrum, a ceremony that provides a visitor with temporary access to and use of land.
