If you’ve made a mistake with your transfer, it may be possible to cancel it if it hasn’t yet been delivered or arrived at its destination, particularly if you’ve sent money to New Zealand, which shares Australia’s banking system. However, once it’s been delivered, it usually isn’t possible to get a refund. It’s a safe rule to only send money overseas to people you know or companies you’ve had prior dealings with. Cash pickup transfers overseas are particularly high-risk.
