How about working overtime in Australia?

If you don’t file taxes and work as a cashier, no one will know that you are overtime.

If you file a tax return, the ATO will know your working hours, but because the ATO and the Immigration Bureau are not the same department, they will only be found out during random inspections. If you find out the most, you will be fined.

Basically, all Chinese people in Australia work as cashiers. There are relatively few people who can work for ghosts, and they are basically all Chinese.
