You just go to the embassy and write out a stat dec and provide something that shows where the income is sourced from. This is a new requirement. Maybe your Thai bankbook would suffice or some statement from Australia. Say a payment advice from a real estate agent if you're living off rent, etc. The stat dec only needs to be a few sentences. The embassy has a sample of the preamble that you need to state. I think the fee is 500 baht.

Crooks in what sense? They only act as agents for the embassies.
