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.
[24] Notable is the city's coat of arms[30] in the centre of the ensign and the city's name on the left of the flag, lettered from top to bottom.
The three white rings in the flag intersect to create eight spaces from their loops and exterior, symbolising the unity of the eight amalgamated former councils.
