There is a new seam doing the rounds.

This seam is based around you receiving calls promising $999 in bogus credits on flights and holidays then being asked to hand over their credit card details in return for a credit of $999 towards your winning flight or a holiday.

Both Qantas and Virgin Australia have warnings on their websites.

Remember airlines do not use automated systems in this way.

Scammers pretend to be from reputable businesses and all reports indicate these seam callers have foreign accents and will hang up if you start pressing them for detailed information.

You can still receive seam calls even if they have a private number or have listed their number on the Australian Government's Do Not Call Register. Scammers can obtain your number fraudulently or from anywhere it has been publicly listed. They also use computer generation numbers that are programmed to just keep dialling numbers in numerical order until they get an answer.
