The Torres Strait Islander flag is the official flag of the Torres Strait Islanders, an Indigenous people of Australia. It was designed in 1992 by Bernard Namok, winning a local competition held by the Islands Coordinating Council, and was recognised by the Aboriginal and Torres Strait Islander Commission in June 1992. It was granted official status in 1995 under the Flags Act 1953 along with the Australian Aboriginal flag.

The flag of Australia is based on the British Blue Ensign—a blue field with the Union Jack in the upper hoist quarter—augmented with a large white seven-pointed star and a representation of the Southern Cross constellation, made up of five white stars. Australia also has a number of other official flags representing its people and government bodies.
