This is a question that is evolving over time.

What is an Australian today?

What was an Australian 10 years ago?

What was an Australian 100 years ago?

What was an Australian 500 years ago?

So imo it's a pretty generic, silly question to ponder about, it's like asking what does it mean to be human.

Welcome, Gazza91

You are very correct.

Names and boundaries are not the reality, they are superimposed over the reality. They can be used to handle everyday practicalities, but have no use in finding the truth of anything.

Since "Australian" has no everyday practicality unless you are employed by Australian border police or the like where you are being paid to let "Australians" through but not others, others have no true need to use that limiting term.

What is an Australlian is identifying the attitudes and behaviours and social culture of what is typical Australian. NITV believes it is being smeared in clay, standing in smoke, and doing a war dance - Is this Typical?

Just as bad as blue and white zinc on the nose, a floppy hat, beach towel and thongs in the Aussie flag, all made in China of course. Standing on the hot sand of Bondi Beach skulling cans of VB.

Josephus,

You ask if "being smeared in clay, standing in smoke
and doing a war dance - is this typical?"

It's more typical than paying homage to a 95 year old
filthy rich foreign monarch living in a foreign land
with a morally questionable family living off
the public purse whose visits we have to pay for.

In my opinion Foxy is a filthy monarch.
