The City of Sydney Archives in Australia has free, online Sydney City Directories for the years 1858 to 1933.

City Directories contain an alphabetized list of residents with their addresses, spouse’s name, profession, and often a reverse lookup by address. They often contain historical information about a locale and they’ll usually contain a separate business directory.
