Window dressing bank accounts for retirement extensions has become a big business.
When my friend died following a motorbike accident, I took his passport and death certificate to immigration. I mentioned he had one of these hookey no money in the bank extensions and she said “Yes we know, we know who they all are”. Before he died he told me the local Immigration Office wouldn’t accept his 90 day reports and his visa agent had to do them. Since that time, I think at least one local officer has joined that scheme. At least one local visa agent is now offering the service and other friends with these hookey visas is doing her 90 day reports locally.
Actually, this process is a fairly smart way to identify who to later target, but I don’t think that was ever their intention.
The Elite visa company (TPC) do have access to our bank accounts, when I applied I was asked about major repeated withdrawals made by my ATM card in Australia. If they have access, probably every gov’t agency does.
