In 1770, after returning to England from their voyage in the South Pacific, Cook and Banks brought with them a large collection of flora and fauna, along with cultural artefacts from their most recent venture. The find included a collection of roughly fifty Aboriginal spears that belonged to the Gweagal people. Banks was convinced the spears were abandoned (on the shores of Kurnell) and "thought it no improper measure to take with them all the lances which they could find, somewhere between 40 or 50".
