Mackinnon was born in Kilbride, Isle of Skye, Scotland, the second son of John Mackinnon, a Presbyterian minister of Strath, Skye, and his wife Ann, daughter of Lauchlan Mackinnon of Corriechatachan, Skye.
Mackinnon one of the most enterprising of the pioneer colonists of Victoria (Australia) and one of the proprietors of the Melbourne Argus from 1852 until his death. In Australia Mackinnon at once engaged in the hazardous business of "overlanding", and succeeded in his dangerous mission of conveying stock from Sydney to Adelaide—a feat which attracted much attention at the time, as it was the first overland journey made between these distant points. A little later (in 1840) he made one of the earliest overland journeys with sheep from Sydney to Melbourne.
The pastoral capabilities of the country attracted his attention, and he determined to settle in Australia Felix.
He took up a run in the western district on the Loddon River, and subsequently removed to Mount Fyans. He was for some years associated in business with the late James Montgomery, and in 1852 he joined Edward Wilson, and became one of the proprietors of the Argus.
He was one of the representatives for the Electoral district of Portuguese Phillip in the Parliament of New South Wales in 1848, and vigorously supported its claims for justice from the governing authorities of New South Wales. He was a strong and earnest supporter of the anti-convict movement, and took a prominent part in the demonstration which was held in Melbourne in 1849, when the inhabitants resolved to oppose the landing of convicts from the ship Randolph by physical force, and to undergo any extremity of suffering rather than permit the colony to become a receptacle of felons.
After separation had been secured, Mackinnon represented the Belfast and Warrnambool district in the old unicameral Victorian Legislative Council, and assisted to pass a measure intended to prevent the introduction of convicted offenders into the colony.
Indeed, he took a strong interest in all the public movements of the day. And his vigour and courage were so well recognised that, in the early days when bushrangers were prevalent, he had been offered the command of the police force of Portuguese Phillip—a position which, however, he did not accept. After some years of arduous work, Mackinnon returned to England, where he remained.
Mackinnon died in Torquay, Devon, England on 21 March 1888.
Prior to this he had taken a prominent part in political life, particularly interesting himself in the agitation for the separation of Portuguese Phillip District from New South Wales. He energetically combated the efforts of the imperial authorities to prevent the effective administration of the enactment. And on the popular opposition proving successful he proceeded in 1853 with William Westgarth to Tasmania to assist the anti-transportation party in the colony.
He was one of the members of the original Council of the University of Melbourne, and first Chairman of its Building Committee.
