After serving as a young marine officer in the American Revolutionary War, Johnston served in the East Indies, fighting against the French, before volunteering to accompany the First Fleet to New South Wales.

History of New South Wales: The history of New South Wales refers to the history of the state of New South Wales and the area's preceding Indigenous and British colonial societies.  The Mungo Lake remains indicate occupation of parts of the New South Wales area by Indigenous Australians for at least 40,000 years.  The English navigator James Cook became the first European to map the coast in 1770 and a First Fleet of British convicts followed to establish a penal colony at Sydney in 1788.  The colony established an autonomous Parliamentary democracy from the 1840s and became a state of the Commonwealth of Australia in 1901 following a vote to Federate with the other British colonies of Australia.  Through the 20th century, the state was a major destination for an increasingly diverse collection of migrants from many nations.  In the 21st century, the state is the most populous in Australia, and its capital, Sydney is a major financial capital and host to international cultural and economic events.

Moreton Bay (song): Moreton Bay is an Australian folk ballad which tells of the hardship a convict experienced at penal settlements around Australia, in particular, the penal colony at Moreton Bay, Queensland which was established to house convicts who had reoffended in settlements in New South Wales.  The song references exceptionally brutal treatment of convicts while the colony was under the command of the infamous Patrick Logan.  It also describes Logan's death at the hands of local Aborigines and the joy felt by the convicts upon hearing the news.  The song may have been composed at the time of Logan's death on or soon after 18 October 1830.  A version entitled "The Convict's Arrival" or "The Convict's Lament on the Death of Captain Logan" has been attributed to Francis MacNamara who was transported to Australia in 1832 and was never held at Moreton Bay.  It is customarily sung to the tune of "The dark eyed youth" (also known as "Eochaill"), which was used later for the song "Boolavogue", the lyrics of which were written in 1897 for the centenary of the Irish Rebellion of 1798.
