Geometric description

All four designs have the same geometry.

Let the flag be 100 units high and 160 units long. Let each point on the flag be represented by the coordinates (x,y), where x is the distance from the left (pole) edge, and y is the distance from the bottom edge; that is, let (x,y) be Cartesian coordinates with the origin at the bottom left corner.

Then the vertices of the boomerang are

(90,0) (120,60) (90,100) (105,100) (138,62) (100,0)

and the stars of the Southern Cross are arranged as follows:

                 Centre    Outer   Inner   No. of
                 coords.   diam.   diam.   Points

Alpha Crucis     (50,17)    20       9        7
Beta Crucis      (25,56)    20       9        7
Gamma Crucis     (50,83)    20       9        7
Delta Crucis     (72,62)    20       9        7
Epsilon Crucis   (60,46)    11       5        5 .

Notice

I use my real name on the internet. Critics who send recycled arguments under assumed names from fly-by-night email accounts will not be dignified with any response. War veterans who claim to have fought “for the Flag” will be respectfully asked whether, if 51% of the Australian people were to vote for a new National Flag, the other 49% would be justified in taking up arms to defend the old one.

Acknowledgment

The National Flag design is a rearrangement and simplification of Brendan Jones's “Reconciliation” design. Any other similarity between one of the above designs and an earlier design by another artist, published or unpublished, is coincidental.
