This comment caught my eye:
There is a mistake somewhere. Either the number 55K is wrong or you meant to say Greece rather than Australia. I know that the Oz economy is doing well selling natural resources to the booming Asian economies. However, this seems too much. Someone on the government dole in the US would need to have many illegitimate children to be paid that much.
I would agree with you that those figures are probably not correct. However, Kuna is actually talking about benefits given to those on minimum wage rather than those without work as you refer to above.
I don't know about Australia, but I can give you the comparable figures for the UK.
A single person in the UK working 40 hours a week on the minimum wage of £5.93 per hour will earn £12,334 per year - or 19,735 USD for the Yanks reading this.
A single person will also be entitled to £220 in benefits called 'working tax credits' and also, typically,


£1,500 help towards their rent, called 'housing benefit' - this will be higher in London.
To take a more extreme example. A couple with the husband working on minimum wage and the wife staying at home looking after two children under the age of three.
They would get £6,800 a year in 'housing benefit;' to help with their rent and get further benefits of £6,000 a year called 'child tax credits' and 'working tax credits'.
This would give them a total income of 12334 + 6800 +6000 = £


24,334
Converting this to AUD gives a total income of approx 37,000 AUD - some way short of the 55k figure that Kuna gives for Australia.
It may well be that Australia is a lot more genorous than the Uk - but I doubt it somehow.
