For anyone researching street and locality names in Ballarat, the following link should take you to an alphabetical list of locality, street and reserve names within the present City of Ballarat.
http://www.ballarat.vic.gov.au/media/2253695/roads_and_open_space_historical_index.pdfThis document lists current and historical (and also currently proposed) names, with cross references where appropriate, together with the origin of the name and date of name change where that information is available. The document is updated on a reasonably frequent basis.
Over a period of around 70 years, most longer streets in Ballarat were renumbered using a block system, in which numbers allocated to properties in each block increased by 100. For example, travelling west along Sturt Street, no 1 Sturt Street is on the south-west corner of Grenville Street South, no 101 is on the south-west corner of Albert Street, no 201 on the south-west corner of Lydiard Street South, and so on. Many Ballarat streets also have a North and a South, with the same numbers in both sections, so it's ESSENTIAL to ensure the appropriate North or South is included in addresses.
Unfortunately, except for a small number of more recent renumberings, records showing how the block numbers relate to the original numbers have been lost. To aid research, the document also gives suggestions for finding present-day numbers for addresses shown on records that pre-date the renumbering.
Hope this helps anyone researching in the Ballarat area.
