Ned Kelly (1970 film): Ned Kelly is a 1970 British-Australian biographical (and part musical) film.  It was the seventh Australian feature film version of the story of 19th-century Australian bushranger Ned Kelly.  It is notable for being the first Kelly film to be shot in colour.

Dan Kelly (bushranger): Daniel "Dan" Kelly (1 June 1861 – 28 June 1880) was an Australian bushranger and outlaw.  The son of an Irish convict, he was the younger brother of the bushranger Ned Kelly.  Dan and Ned killed three policemen at Stringybark Creek in northeast Victoria, near the present-day town of Tolmie, Victoria.  With two friends, Joe Byrne and Steve Hart, the brothers formed the Kelly Gang.  They robbed banks, took over whole towns, and kept the people in Victoria and New South Wales frightened.  For two years the Victorian police searched for them, locked up their friends and families, but could not find them.  Dan Kelly died during the infamous siege of Glenrowan.

Captain Thunderbolt: Frederick Wordsworth Ward (1835 – 25 May 1870), better known by the self-styled pseudonym of Captain Thunderbolt, was an Australian bushranger renowned for escaping from Cockatoo Island, and also for his reputation as the "gentleman bushranger" and his lengthy survival, being the longest roaming bushranger in Australian history.

Fred Lowry: Thomas Frederick "Fred" Lowry (1836 – 30 August 1865) was an Australian bushranger and member of the Frank Gardiner–Ben Hall gang.  Born near Fish River in New South Wales, he was a stockman before taking to bushranging, mainly in and around the Blue Mountains.  Throughout 1862 and 1863, Lowry was involved in shootings, an escape from prison, and robberies, including the bail up of the Mudgee Mail which earned him and his companions £6,000, the largest haul in bushranging history since the Lachlan Gold Escort robbery the previous year.  In August 1863, Lowry was cornered by police inside a hotel outside Goulburn and engaged them in a gun battle, during which he was fatally shot in the throat.  Before losing consciousness, he told the policemen, "Tell 'em I died game!"  It is for these iconic last words that Lowry is chiefly remembered.
