He was one of the first unauthorized colonists in Melbourne and built a weatherboard home on the eastern side of the future city, despite warnings that he would have to move. For nearly 3 years he waged a successful war of maneouvre against the Superintendent Charles La Trobe, appealing over La Trobe’s head to Governor Richard Bourke in Sydney, Wrighte managed to thwart La Trobe's efforts to evict him for much longer that should have been the case.
In 1838, Wrighte founded Box Hill by establishing his pastoral run 'Marionvale'. The stones from his original homestead now form the Pioneers' Memorial outside of the town hall.
Wrighte also had pastoral interests in New South Wales.
