What is the meaning of the Australian flag?

The upper left corner of the national flag is the pattern of the British flag, which shows the traditional relationship between Australia and Britain. The largest seven-pointed star symbolizes the six states and the Federal District (Northern Territory and Capital Territory) that make up the Commonwealth of Australia. Five small stars represent the Southern Cross constellation (one of the small constellations in the southern sky, although the constellation is small, there are many bright stars). It means "southern continent", which means the country is in the southern hemisphere.
