The Eureka Flag doesn't enjoy wide popularity, but there are some who are fanatically loyal to it. Regardless of its emotive appeal (positive or negative), I find that its aesthetics leave me cold. Blue-and-white is a weak colour combination (sorry, Greece and Israel), and there isn't any contrast between the white stars and their white background, just a thin blue line as a separator.
Southern Horizon takes the safe route of proposing a compromise design that balances the conflicting requirements of continuity and change.
The new style also seemed to shine like real stars.
Golden Wattle is hence not fully authentic in terms of colour, and another design that uses the right colours in a better combination might therefore stand a competitive chance.
Although in general I'm not a fan of animals on flags, it's undeniable that the presence of a kangaroo will cause a flag to be instantly recognisable around the world as the Australian flag. It's just that most designs involving roos have been terrible.
But then Ian McLellan began to produce a few interesting ones that didn't look bad at all.
This last design inspired me to create the following tricolour:
I had read a few days earlier on the site that vertical tricolours symbolised a revolt against a European monarchy. That's appropriate in the Australian context, since the quest to remove the Union Jack from the flag is a revolt of sorts against the British monarchy.
The roo-on-ochre theme makes the flag instantly recognisable as the flag of Australia.
The golden wattle, rendered in green-and-gold, should satisfy those who believe the Australian flag must carry the "national colours". I'm a bit meh on this, but whatever.
I personally like the heraldic colours of red, white and blue, and I'm fond of the Southern Cross (especially in Brian Nedic's futuristic style), so that makes up the third stripe.
