Which countries have the Southern Cross on their flags?

The center position of the Southern Cross is right ascension 12: 20, and right declination -60. Located between Centauri and Flies, it is the smallest of the 88 constellations in the whole day. The main bright stars in the constellation form a cross, one of which points to the south celestial pole. Because there are no bright stars near the south celestial pole, this cross is no less important in the southern hemisphere than the Beidou in the northern hemisphere. Although the Southern Cross is small, there are many bright stars. Alpha star is a famous bright star in the southern sky and a binary star. The beta star is a second-class star, with seven stars brighter than the fourth-class star.

Australia, New Zealand, Brazil, Papua New Guinea and Samoa all have the Southern Cross on their flags.
