Regarding the millionaire thing. It depends on what is meant by millionaire.
There are one or two who run millionaire businesses.
There is one who lives in a 6 million dollar home - they may not have the cash but if the home was sold and the profit divided between the family, they could get themselves a tidy sum.
One works in a well paid job and can afford to live near Circular Quay and considering Sydney prices are astronomical they would be earning good coin.
So there's a few that could fall into the millionaire category depending on salary, property, assets,etc.
