An influx of interstate and overseas migrants, particularly Irish, German and Chinese, saw the development of slums including a temporary "tent city" established on the southern banks of the Yarra.

In the aftermath of the Eureka Rebellion, mass public support for the plight of the miners in Melbourne resulted in major political changes to the colony. The various nationalities involved in the Eureka Stockade revolt and Burke and Wills expedition give some indication of migration flows in the second half of the nineteenth century.
