The flag contains the Commonwealth star and the Southern Cross. The colours are selected and placed in an order that is significant. The blue, white, and red represents Great Britain, the first European nation to significantly colonize Australia. The red, gold, and black recalls the Aboriginal flag. The red line is larger that the white and gold since it represents "blood," more significantly the blood of all Australians which transcends race or ethnicity. It also meets in the middle of the meeting of European and Aboriginal--a common bond and the "lifeblood" of the Australian nation moving forward in the 21st century.
