One of the great themes of modern history is the movement of poor people across the face of the earth. For individuals and families the economic and psychological costs of these transoceanic migrations were severe. But they did not prevent millions of agriculturalists and proletarians from Europe reaching the new worlds in both the Atlantic and the Pacific basins in the nineteenth century. These people, in their myriad voyages, shifted the demographic balance of the continents and created new economies and societies wherever they went. The means by which these emigrations were achieved are little explored.
Most emigrants directed themselves to the cheapest destinations. The Irish, for instance, migrated primarily to England, Scotland, and North America. The general account of British and European emigration in the nineteenth century demonstrates that the poor were not well placed to raise the costs of emigration or to insert themselves into the elaborate arrangements required for intercontinental migration. Usually the poor came last in the sequence of emigration.
The passage to Australasia was the longest and the most expensive of these migrations. From its foundation as a penal colony in 1788, New South Wales depended almost entirely on convict labor during its first four decades. Unambiguous government sanction for free immigration emerged only at the end of the 1820s, when new plans were devised to encourage certain categories of emigrants from the British population. As each of the new Australian colonies was developed so the dependence on convict labor diminished.
