Police say they are dealing with an increasing number of people being ripped off through simple scams.
Complaints are coming in almost daily and often it's the "really simple" schemes that lure the most victims.
Detective Sergeant Aaron Pascoe of the financial crime unit said scams would continue unless the public became more savvy about how the frauds work.
He gave a rundown of some of the most recent and common scams.
"People selling airline tickets for cash - but airline tickets are purchased using stolen credit card details and the tickets are cancelled, sometimes in the middle of the travel and while the victims are overseas."
