Flag of Heard Island and McDonald Islands
The Flag of Heard Island and McDonald Islands represents one of the most remote and uninhabited territories on Earth. Located in the southern Indian Ocean, these subantarctic islands are administered by Australia and are primarily known for their volcanic landscapes and protected wildlife. Because the territory has no permanent population, its flag symbolism focuses on governance and environmental stewardship rather than national culture. Understanding the Flag of Heard Island and McDonald Islands helps explain how sovereignty and administration are visually represented in isolated regions of the world.

The Flag of Heard Island and McDonald Islands is based on the Australian Blue Ensign. It features a dark blue field with the Union Jack in the upper hoist-side corner.
On the fly side of the flag appears the Commonwealth Star and the Southern Cross constellation, which are key elements of the Australian national flag. There is no separate territorial emblem added to the design.
