Your government may not need additional taxes so they prefer not to tax its people because the Australian economy is robust, but other countries are not that robust they need additional funding so instead of resorting to borrowing from local and international banks they prefer to tax the gambling sector.
I have seen how taxing the gambling sectors can do to one's economy because I'm living in a country where so many things are being taxed, and gambling is one of these.
Our country takes 20% of the cut in the winners' winning besides different taxes within the gambling sector, our government is good at collecting these taxes.
That percentage is too big to be collected as tax from the government. Why not just them give you some money to help them play the game and keep the winnings to themselves. This is ridiculous and any country charging that much from their citizens is just showing how capitalist they are and it is also a big sign of being strict with your belongings and not ending if for the government to take that large amount of money into their custody for your big wins which does not come very often. There is no explaining that can justify this overzealous price paid by them and it’ll be just be them been greedy and selfish of not taken what we can as well see as normal or just at an amount that is considered just beyond average.
