Inhabitants of Bendigo are known as Bendigonians.Originally taking its name from the Bendigo Creek, the name became official in 1891.Bendigo is one of the most significant Victorian era boomtowns in Australia. Gold was discovered in 1851 at The Rocks on Bendigo Creek and the Bendigo Valley was found to be a rich alluvial field where gold could easily be extracted. News of the finds intensified the Victorian gold rush bringing an influx of migrants to the city from around the world within a year and transforming it from a station to a major settlement in the newly proclaimed Colony of Victoria.Bendigo is notable for its Victorian architectural heritage and gold mining history. Since 1851 over 22 million ounces of gold have been extracted from its goldmines, making it the highest producing 19th Century goldfield in Australia in the nineteenth century and the largest gold mining economy in Eastern Australia. It is the largest finance centre in Victoria outside of Melbourne as home to Australia's only provincially headquartered retail bank, the Bendigo Bank, and the Bendigo Stock Exchange (BSX).
