The Flag on our Flag symbolises our 'service' to the International arena.
With the British Union Jack representing a 'Political' nation - our Flag shows the recognition of that nation's POLITICAL involvement here.
Flags are a Political work of Art. Always have been, besides Battle Standards (Military).
If we had a Flag representing Switzerland's Medical involvement here...
If we had a Flag representing other nations and their involvements here...
We could have a Flag with a large circle of little Flags representing all the Nations that have made an 'involvement' here...
Such is the 'multi' of culturalism here.
Like I said - there is no official 'Australian' past beyond a British one (since 1788), an Aboriginal one (since like 50,000yrs ago) and an Americanised Colonial one (Man of Snowy River, Drizabone and other 'cliche' Down Under stuff).
We celebrate Australia Day as a celebration of a 'Past' event.
One day, we may have a Flag representing a 'Domestic' culture and a culture that belongs to the 'Future'
...but that's why we are here: To Conquer 'Time'.
Just like N.america was a conquest of 'Space' - by them sailing off the edge of the world.
We are here to conquer 'Time' ...and like doing 'time' for our
Convictions, we may indeed be FREE from the PAST.
...only time will tell
