A flag is an extraordinary thing. A mere cut of cloth and yet the only piece of material that people are prepared to fight and die for - with the possible exception of a Louis Vuitton handbag. 
The Americans love their flag so much they wrote a song about it, and then made that song their national anthem.
The French love their Tricolour and the Brits love their Union Jack, to the point that every time a royal takes a buggy ride the whole population seems to just whip one out of its pocket.
And the flag of Nazi Germany is still considered such a powerful instrument of evil that it is banned in Europe's largest nation even to this day.
A flag, in short, is nothing to be sneezed at - indeed in many countries doing so could land you in jail.
That is because desecrating a flag is considered a desecration of the whole country, its people and its values.
Yet in Australia there remain persistent calls for us to change our own flag because it no longer represents our people or our values.
The constant complaint is of course the presence of the Union Jack and that it no longer befits a multicultural society still struggling to reconcile with its first inhabitants.
Personally, I have no great problem with the Australian flag as it stands. It is a pretty handsome piece of tapestry, better looking than most national standards, and it comes in red, white and blue - clearly a winning combination as far as flags go.
More importantly, it is far superior to the god-awful alternative designs that are inevitably thrown up - sometimes literally by the looks of them - every Australia Day.
To realise the dangers of putting national symbols in the hands of graphic designers one need only observe the new five-dollar note, which looks like a close-up of a Petri dish next to an apparently deceased Queen Elizabeth.
No doubt it was the giant yellow streptococci on her left that did her in. Yet it remains almost certainly inevitable that the flag will one day change. The real question is what we are going to change it to.
The answer? Eureka!
The Eureka flag is everything our nation needs.
Yes, it has been co-opted by both the left and the right - just this week the Australian Workers' Union tried to stop the Australia First Party from using it - but that is all the more reason to reclaim it for all Australians.
In fact its true nature encapsulates a holy trinity of unity. It is a symbol for workers' rights, which will please the left; opposition to taxation, which will please the right; and national independence, which will please the republicans.
It is uniquely Australian, deeply significant and mightily powerful. Indeed, the very name itself is calling to us.
"Eureka" means, quite literally: "I have found it!"For more amazing discoveries and impromptu rebellions watch Joe on Studio 10 from 8.30am weekdays on Channel 10.
