George Thomas Clarke (13 November 1853 – 11 March 1925) was an Australian local government politician, accountant and estate agent.

His elder brother William Clarke became prominent in banking and rose to be Member of Parliament for Orange and Minister for Justice in the Government of the Colony of New South Wales.

[2] After receiving his education at Collins Street Grammar School, Clarke studied accountancy but owing to health issues decided to travel away from busy Melbourne, taking a sea voyage in 1875.

While in New Zealand, in 1876 Clarke joined the Independent Order of Odd Fellows, an interest in which he carried over when he returned to Australia, arriving in Sydney in the early 1880s.

[11][12] Survived by two sons, Clarke died while still serving as a North Sydney alderman on 11 March 1925 at his Wollstonecraft residence on Milner Crescent, "Domus", and was buried with Congregational and Masonic rites at Waverley Cemetery.
