Context: The main passenger airport serving the metropolis and the state is Melbourne Airport (also called Tullamarine Airport), which is the second busiest in Australia, and the Port of Melbourne is Australia's busiest seaport for containerised and general cargo. Melbourne has an extensive transport network. The main metropolitan train terminus is Flinders Street Station, and the main regional train and coach terminus is Southern Cross Station. Melbourne is also home to Australia's most extensive freeway network and has the world's largest urban tram network. 

Between 1836 and 1842 Victorian Aboriginal groups were largely dispossessed[by whom?] of their land. By January 1844, there were said to be 675 Aborigines resident in squalid camps in Melbourne. The British Colonial Office appointed five Aboriginal Protectors for the Aborigines of Victoria, in 1839, however their work was nullified by a land policy that favoured squatters to take possession of Aboriginal lands. By 1845, fewer than 240 wealthy Europeans held all the pastoral licences then issued in Victoria and became a powerful political and economic force in Victoria for generations to come.
