Career
Carter arrived in the colony of Van Diemen"s Land in 1835, and worked as a storekeeper and merchant. He had a hardware and grocery store at the corner of Collins and Elizabeth streets, before relocating to the corner of Murray and Collins streets, where he established the firm of William Carter and Company, wholesale wine and spirit merchant. Carter was appointed as a Commissioner of the Peace, and in this capacity visited the Brickfields Hiring Depot in 1844 with William Watchorn, and reported on the condition of female convicts there.
They stated that "the whole system is one of great mismanagement dangerous to the community & destructive of any hope that might otherwise be entertained of the moral reformation of any of the Class."
Carter served as an alderman for the City of Hobart from 1846–1847, and again, this time as mayor, from 1853–1854.
In this capacity he was involved in laying the foundation stone for the Playhouse Theatre and Union Chapel. Carter moved to Toorak in Victoria toward the end of his life, and died there on 8 July 1878.
Carter has been described as a "shrewd and astute business man," while his obituary noted that he "was especially distinguished for his aversion to slander and backbiting." He was "frequently known, when people began to speak against others, to walk away, so as not to be led into saying a word in the way of reproach of absent persons.".
