In 1843 William Innes was appointed by the governor to be a member of the first local council for the district of Maitland. 
William Innes' death was reported in the Maitland Mercury in 1869 - On the 31st July at his residence, 197 Macquarie Street, Sydney, William Innes Esq., aged 69 years. An old and much respected colonist of the Hunter River District. He was born in Caithness, Scotland and arrived in the colony in 1822 when he obtained a grant of land in the Hunter River district. After spending a few years in the Commissariat service in Sydney and Newcastle, he took up his abode on his own property near West Maitland, now in the possession of Mr. Charles Button. For upwards of fifteen years he occupied the position of local director of the Maitland branch of the Bank of Australasia, and he discharged the duties of that office with the greatest satisfaction to the bank and to the public, until failing health obliged him to leave the district. He was a man of great information, but of a very retiring disposition. He was universally esteemed for his sterling worth, and greatly beloved by those who enjoyed the privilege of his friendship. His loss will be felt by many to whom he has freely extended his liberal, but unostentatious, charity. We understand that he has left in the hands of trustees £500 to be appropriated to charitable purposes.  John Nowlan of Eelah and Walter Scott of Wallalong were Executors of William Innes' estate.
