What will happen if the Australian tourist visa is hacked?

I don't have any welfare, I don't have citizenship, I live on a discounted salary, and I hope to get Amnesty. I barely lived to be thirty or forty years old and had a lot of beards. I stayed in the rental house and watched others drive sports cars. If you find that your social security and other things are gone, you don't know who to go to. If my ID card is changed, your ID card may be invalid and cannot be renewed.
