Australia's [[South Australian Railways D class|first 4-4-0 locomotives]] were introduced by the [[South Australian Railways]] in 1859. From that initial order for two locomotives, the numbers of this wheel arrangement multiplied and eventually appeared in most of the Australian colonies. Tender, tank and saddle tank versions, varying in size from small locomotives to express passenger racers with {{convert|6|ft|6|in|mm|0|abbr=off|comma=off}} driving wheels, worked in [[Victoria (Australia)|Victoria]], [[New South Wales]], [[Western Australia]] and [[Tasmania]] on {{Track gauge|1067mm|comma=off}}, {{Track gauge|1435mm|comma=off}} and 
{{Track gauge|1600mm|comma=off}} gauge.<ref name="Oberg">Oberg, Leon. (1975). ''Locomotives of Australia''. Sydney, London: Reed.</ref>

The locomotives originally came from British builders such as [[Dübs & Company]] and [[Beyer, Peacock & Company]]; however, from the late 1870s into the 1880s, railways also bought locomotives from American builders, mostly from Baldwin, and a few from the [[Rogers Locomotive & Machine Works]] in [[New Jersey]].  From the 1880s onward, local firms such as [[James Martin & Co]]. in [[Gawler, South Australia]], and the [[Phoenix Foundry]] in [[Ballarat]], Victoria would also build them. In New South Wales and Victoria, the 4-4-0 were predominant for mainline passenger services until the early 1900s. In Western Australia, some were later converted to a {{whyte|4-4-2}} wheel arrangement.<ref>Australian Railway Historical Society,'' A Century Plus of Locomotives'' ''New South Wales Railways 1855-1965'', ARHS, Sydney, 1965</ref><ref>Victorian Railways, ''Power Parade: 1854-1954'', Victorian Railways, 1954</ref>
