Local prosperity was briefly thrown into a trough following the allure of the Californian gold fields, with employers hard-pressed to find enough experienced workers at the right price. This trend, however, was abruptly reversed within a short space of time. Indeed, the pace of the Millers Point community accelerated rapidly in the 1850s to accommodate the frenzy generated by the discovery of gold at Bathurst and the consequent flood of immigrants into New South Wales. This coincided with an increase in large-scale exports, particularly wool, to diverse international markets. By the 1860s the earlier mix of worker and merchant/gentry housing began to be overtaken by commercial needs and by the creation of new residential streetscapes such as Argyle Place and Kent Street, with a distinct change in the size of residential buildings and an increasing use of materials such as slate. The mercantilist face of Millers Point also changed, with the construction and extension of larger jetties and warehouses for imported goods as well as staples such as wool, coal and flour. Gradually this period of upgrading saw the small scale industries and structures superseded by the encroaching larger-scale warehouses, responding to the demand created by larger vessels. A corresponding shift in the population showed that the artisans and merchant gentry were moving elsewhere, and that Millers Point was overwhelmingly oriented towards booming export industries, with a workforce and resident population of unskilled and semi-skilled labourers catering for specific tasks.
