 | | Flag of the City of Hobart | 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.

 | | Flag of the City of Launceston | The Launceston flag design is based on the city's coat of arms granted by the College of Arms, London, on 11 June 1957.

The strip across the top with the jagged edge is green to represent the city's parks, gardens and surrounding countryside. Waratah flowers at the top symbolise all flowers and similar beauties of nature. The ingots are included because Launceston used to be a large tin smelting centre. The little circle at the river junction is Launceston. |
