1 While we will 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 restrictions and congestion in our delivery network at the relevant time.

For detailed information on available service options and charges please refer to our Post charges guide (PDF 463kB).

2 All delivery times are based on the number of business days items take to arrive following the day of posting. Monday - Friday clearance times for street posting boxes vary depending on location (check the details on your local box). Items posted after the clearance time and on weekends or public holidays are considered to be lodged the next business day.
