Hi all,
I've called up ScamWatch and they said that they cannot deal with it and that this is a police matter.
I just went to the local police station and the policewoman said that this is not a crime yet and she can't see how it would be. If he went to the airport and the ticket is not valid, then it would be a fraud and a police matter. However, it seems now that everything is legitimate. As long as we pay for the airline ticket, its fine. If it is a stolen credit card matter, then it is a matter between QANTAS and Final Flight. In any case, she said that last minutes tickets are usually sold at such low prices.
The police recommends for my dad to leave tomorrow and see if it is a valid ticket. The risk is that he won't get on a flight. She said this is what she would do. No one is going to arrest him or anything because we really did purchase it.
