The Fitzroy Iron Works at Mittagong, New South Wales, was the first commercial iron smelting works in Australia. It first operated in 1848. From 1848 to around 1910, various owners and lessees attempted to achieve profitable operation but ultimately none succeeded. More than once, new managers repeated more or less the same mistakes made by earlier ones. Over the second half of the 19th century, the name 'Fitzroy Iron Works' became almost synonymous with lost opportunities, repeated failure, lost capital, misplaced trust, and general misfortune.
