There are many styles of mandolin, but four are common, the Neapolitan or round-backed mandolin, the carved-top mandolin and the flat-backed mandolin. The round-back has a deep bottom, constructed of strips of wood, glued together into a bowl. The carved-top or arch-top mandolin has a much shallower, arched back, and an arched top—both carved out of wood. The flat-backed mandolin uses thin sheets of wood for the body, braced on the inside for strength in a similar manner to a guitar. Each style of instrument has its own sound quality and is associated with particular forms of music. Neapolitan mandolins feature prominently in European classical music and traditional music. Carved-top instruments are common in American folk music and bluegrass music. Flat-backed instruments are commonly used in Irish, British and Brazilian folk music. Some modern Brazilian instruments feature an extra fifth course tuned a fifth lower than the standard fourth course.

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. Chinese migrants founded the Melbourne Chinatown in 1851, which remains the longest continuous Chinese settlement in the Western World. In the aftermath of the Eureka Stockade, mass public support for the plight of the miners resulted in major political changes to the colony, including changes to working conditions across local industries including mining, agriculture and manufacturing. The nationalities involved in the Eureka revolt and Burke and Wills expedition gave an indication of immigration flows in the second half of the nineteenth century.
What term is given to the slums established on the souther banks of the Yarra?
