Australia — World Flags

The story behind the answer

This is Australia’s flag: the Union Jack reflects British heritage, the large seven-point Commonwealth Star stands for the six states plus the territories, and the Southern Cross marks its Southern Hemisphere identity. The design emerged from a 1901 public competition after Federation; the star gained a seventh point in 1908.

Memory tip: Southern Cross + big seven-point star = Australia “Down Under.” By contrast, Tuvalu’s flag has scattered stars on light blue, Nauru shows a single star beneath a horizontal stripe, and Kiribati features a bird and rising sun over waves. Remembering those differences helps you spot Australia instantly.
