Jeff Thomson, « Construction Details of the Australian Flag », sur FOTW Flags Of The World website, Jon Radel, (consulté le ) : « "The 1901 Southern Cross star-points ranged from nine (Alpha) to five (Epsilon) and inner diameter of each was 4/9 of their outer diameters. Beta, Gamma and Epsilon were the same outer diameter as today, Alpha was 1/6 and Delta 1/10 of the fly width. In 1903 Alpha, Beta and Delta were altered to the same design as the Gamma Star (1/7 fly width, seven points) thus making the Southern Cross the same as on the current flag. The 1901 six-point and 1908 seven-point Commonwealth Star outer diameters were both 3/10 of the fly width. However the inner diameters were different. The six-point was half, and the seven-point is 4/9 of the Commonwealth Star outer diameter." »
