Establishment of further colonies

Pastoralists from Van Diemen's land began squatting in the Port Phillip hinterland on the mainland in 1834, attracted by its rich grasslands. In 1835, John Batman and others negotiated the transfer of 100,000 acres of land from the Kulin people. However, the treaty was annulled the same year when the British Colonial Office issued the Proclamation of Governor Bourke. The proclamation meant that from then, all people found occupying land without the authority of the government would be considered illegal trespassers. In 1836, Port Phillip was officially recognised as a district of New South Wales and opened for settlement. The main settlement of Melbourne was established in 1837 as a planned town on the instructions of Governor Bourke. Squatters and settlers from Van Diemen's Land and New South Wales soon arrived in large numbers. In 1851, the Port Phillip District separated from New South Wales as the colony of Victoria.
