1 Our regular Parcel Post and speedy Express Post delivery services are suitable for sending items up to $100 in value. If your item is valued over $100 – such as jewellery, electronics or passports – we recommend you add Extra Cover.
Extra Cover provides loss or damage cover for items valued $100 to $5000. If your parcel is lost or damaged and you haven’t purchased Extra Cover, compensation up to $100 and a postage refund may be payable. Subject to the Australian Consumer Law, Australia Post does not accept liability for any consequential or indirect loss or damage arising due to any failure related to our service. Neither the cover included with our service nor the purchase of Extra Cover limits any rights you may have under the Australian Consumer Law.
