Mackenzie and Wilson are notable as being among the main proponents and financial backers of The Wool Road and the new port of South Huskisson (now Vincentia).
[27] In 1838, he became a Police Magistrate,[28] at Braidwood, although in that judicial role he attracted serious criticism and controversy; it appears that he ran his courtroom, in an idiosyncratic and authoritarian manner, with regard neither for the rights of defendants nor the freedom of the press.
[29][30][31][32][33][34] Mackenzie was ruined financially, in the aftermath of the economic depression of the early 1840s, no doubt complicated by the failure of the privately-owned Wool Road and the port of South Huskisson.

One of his assigned convicts, Cornelius Flynn, bore on his back the scars of harsh corporal punishments carried out on Mackenzie's orders.
[56] In the 1860s and into the early 1870's, Andrew was a prominent citizen of the area around Tomerong, albeit one subjected to some public mockery by his opponents.
[57][58][59][60][61] Yet, despite his lands and his wealthy grazier sibling relatives, Andrew Mackenzie died, in August 1878, intestate and apparently in a state of near starvation, at North Huskisson.
