1 While we endeavour to meet this timetable, the actual delivery speed will depend on where in each state/territory the item is being posted from/to, and the level of congestion in our delivery network at the relevant time. All delivery times are based on the number of business days items take to arrive following the day of posting. See delivery times for specific routes.

2 Next business day delivery is only available within the Express Post next business day delivery network. The national next business day delivery network operates between capital cities (excluding Darwin; and, for Perth, delivery into the CBD only) and some major centres. Express eParcel is not covered in the Express Post guarantee.

3 Track events will vary depending on how your item is lodged and delivered. For details visit our tracking service.

4 Express Post comes with up to $100 compensation included. Additional charges for Extra Cover apply. Extra Cover provides you with cover for the specified value of your item (up to $5,000 or part thereof) if your item is lost or damaged while being carried by Australia Post. Visit optional extras for more information. 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 compensation included with our service nor the purchase of Extra Cover limits any rights you may have under the Australian Consumer Law.
