Batman sailed from Launceston in the schooner Rebecca on 10 May 1835 and landed at Indented Head on the Bellarine Peninsula in Port Phillip Bay on 29 May 1835. Between 29 May and 10 June, Batman claimed to have explored an area, including; the Bellarine Peninsula, the eastern part of the Surf Coast, the coastal areas of Geelong to Port Melbourne, northeast from Geelong to either 'Mount Iramoo' near Sunbury or Mount Koroit north east of Melton, and easterly (his journal suggests he made it only to either Merri Creek or Edgars Creek near Fawkner, or perhaps the Darebin River or Plenty River, but the subsequent maps by Wedge suggest a far greater easterly point), and southwest to Melbourne and Port Melbourne. Batman's journal lists 6 June as the day he encountered Kulin Nations peoples and their leaders. Batman claimed a ceremony was held where he proclaimed the treaty and then exchanged his party's gifts in return for the land he explored.
