Australia Post “Returning to sender”: what it means

Who is responsible for a late or missing parcel from Australia Post?

If you bought online from a business, it is in most cases for the seller to put right. The Australian Consumer Law (section 36) says a business that took your payment must supply the goods within the time it stated, or a reasonable time if it stated none, unless the failure was due to someone else or a cause beyond its control and it took reasonable precautions and due diligence to avoid it. A seller may argue that a failure by Australia Post falls under that exception. Section 36 does not itself set out a refund, and the Australian Consumer Law does not say in so many words who carries the risk of a parcel lost in the post. Government guidance in Victoria and Western Australia says the seller is responsible for resolving delivery problems with Australia Post, and that you are entitled to a refund if the seller still does not deliver. State sale of goods law and the seller's terms can also matter and are not covered here. Australia Post generally pays the sender for a lost domestic parcel, but its terms leave the claim with the addressee, up to $100, on parcels a business lodges under Business Standard or Business Express Delivery.

If you posted the parcel yourself, you have a contract with Australia Post, and its General Terms and Conditions apply. Most parcel services include compensation of up to $100 plus a refund of the postage when a parcel is lost or damaged and Australia Post is at fault, and Extra Cover bought when posting can raise that. It pays nothing for delays, except a refund of the postage when Express Post misses its next business day guarantee. Its terms say any rights you have under the Australian Consumer Law apply in addition to them.
