If the income is registered somewhere, like the ATO, that's how you would prove it. However, if it is money paid in cash with no records kept, this becomes harder to prove. If you haven't already, have the CSA collect for you, that way, when they do their tax return you will be given the owed money from that. You can ask the CSA to investigate the other person, however, their response rate is fairly low on this point.
