Wait, how the hell can Australia Post charge you the full AUD 111.60 for a failed shipment when it seems to be the fault of the clerk who approved the shipment against their own rules? And sounds like the package didn’t even leave Australia so even if you should pay for the full mileage it would be 20% at most?

Nah, it's the fault of the sender, all the ruled for what you can send are listed and it's up to you to check and respect them.
