The Union Jack was the flag above the miners fighting for their rights at the Eureka Stockade. It was the banner of those who came to crush them. It didn't fly above Ned Kelly's house, but certainly flew above his gallows. Worst, and most important not to forget, it was the flag of the men who raped and killed Truganini's family before they chained and photographed her. We need a combination of history, reconciliation and future aspirations.
Every nation already has flags of gaudy stripes and unnatural colours.
Gaudy stripes often hide chequered histories. Almost entirely one colour, with a single, simple motif in the corner. The Southern Cross has been with us since the beginning and will be here long after we are one. It is available for all, both rich and poor to see, and sparkles back at both the same way. It was there, on the old flag, at Gallipoli the Somme and the Kokoda track.
