The flag of Hobart City Council, of Tasmania, Australia. Designed in 1951 by Hobart architect and alderman, I.G. Anderson and first flown in 1953.
The star is derived from the arms of Lord Hobart, 4th Earl of Buckinghamshire (1760-1816), Secretary of State for War and the Colonies at the time of colonial settlement (1804), and after whom Hobart is named. The colour used on the arms Lord Hobart was, in fact, sable (black), rather than blue.

The red lion is from the Tasmanian flag - and its location at the top of the shield signifies Hobart's position as the Capital City.
