TransferWise, the Sir Richard Branson-backed international money transfer service, has launched a new campaign starring the boys from satirical site The Betoota Advocate.

The campaign is based on research that found Australians spent $3.9 billion on foreign currency, of which more than $3.1 billion was hidden in fees and markups charged by banks and other currency brokers.

Given the $3.1 billion loss equates to $513 per household every year, TransferWise is asking Australians to share stories about the time they felt ripped off by their bank for a chance to win four cash prizes worth $513 each through the new campaign, “Win it Back”.

The Betoota Advocate editors Clancy Overell and Errol Parker have also thrown their support behind the campaign, starring in a video that chronicles their journey when opening The Betoota Advocate European Bureau. Warning the ad does include unsavoury language.
