This is very interesting. Pretty, people are really trying to protect you here by advising that you declare your income. You will make a bad situation worse by trying to apply for a government benefit. I would be extremely surprised if the ATO is not aware of you already with all the cash coming in to the country. I suggest you get a good accountant who can help you structure your affairs to minimise the tax you pay. However, please have a think about the danger you're putting yourself in. Is it worth going to jail? Yes, this can really happen in Australia and it does. At the very least you can get a permanent criminal conviction against your name and have to pay a lot more money in fines.
You have said that you have more than enough money anyway, so it's not as if paying your taxes would leave you destitute. You're in a fortunate position compared with many people even in Australia, let alone your own country. Don't let greed get the better of you.
At least you have recognised this. I don't think it's uncommon with very attractive women. You have got your sense of value by how attractive you are to men and your power is to get attention from them. It's understandable and quite addictive. But we both know that it cannot last forever. You need to find some other way of establishing your self worth. Maybe you can do that with investment?
