Australia Post is Australia's national postal and parcel service, providing delivery services to households, businesses and online retailers across the country. Its domestic network handles letters, parcels, Express Post shipments, returns and other postal services, supported by Post Offices, parcel-processing facilities and collection options throughout Australia.
For parcel senders, Australia Post offers Parcel Post for regular domestic deliveries and Express Post for faster shipments. Tracking is included with these main parcel services, allowing customers to follow processing, transit and delivery events. Businesses can also use services such as MyPost Business and contract parcel solutions for shipping orders, creating labels and managing higher parcel volumes.
Australia Post also provides international parcel services through International Courier, International Express, International Standard and International Economy. Its international postal network reaches more than 220 destinations, while its own international e-commerce logistics footprint includes operations in China, Hong Kong, Singapore, the United Kingdom and the United States. International services vary in speed, tracking availability, customs requirements and destination coverage.
For online shopping, this combination of domestic delivery and cross-border logistics makes Australia Post an important carrier for both Australian and international e-commerce shipments. Depending on where an order originates, a package may move through international processing facilities before entering Australia Post's domestic network, or an Australia Post shipment may be handed to the postal or delivery network responsible for the destination country.
How to Track Australia Post packages
You can Track an Australia Post package through 4Tracking by entering the shipment's tracking number in the tracking field and starting the search. 4Tracking is a universal package tracking service, so it is especially useful when following international e-commerce orders that may generate tracking events across more than one postal or logistics network.
The tracking number is the key identifier used to retrieve shipment events. Australia Post states that senders can usually find it on a Post Office receipt, on the barcode or removable label of a prepaid satchel, or in shipping records created for the order. Recipients may find the number in the retailer's order confirmation, invoice, dispatch email or Australia Post tracking notification.
After entering the number, Tracking information may show that the shipment has been lodged, processed at a facility, is moving to the next facility, is onboard for delivery, is ready for collection or has been delivered. Tracking events do not necessarily appear continuously. A parcel can travel between processing centres without receiving a new public scan at every stage.
You can also Track directly through the Australia Post website or the AusPost app. Australia Post allows tracking without signing in when you have the tracking number, while a MyPost account and the AusPost app provide additional delivery-management and notification features.
Australia Post tracking number formats
Australia Post does not use one single tracking-number format for every service. Official Australia Post developer documentation shows different article, consignment and barcode identifiers depending on the service and shipping system used.
For eParcel shipments, official technical documentation specifies that an article ID may be 21 characters when it uses a three-character eParcel merchant location identifier, or 23 characters when it uses a five-character identifier. An official Australia Post label example shows an article ID such as 2JD020603601000931508. These identifiers can contain both letters and numbers.
Australia Post's official Tracking API documentation also demonstrates international identifiers in the familiar postal format, such as LX123456789US, consisting of two letters, nine digits and a two-letter country suffix. An international package entering the Australia Post network can retain an identifier issued by the originating postal operator, so the final two letters are not necessarily AU.
Official documentation additionally supports numeric identifiers, including 20-character SSCC article IDs, and Australia Post's Tracking API accepts multiple types of Australia Post article, consignment and barcode IDs. For this reason, you should use the complete tracking number exactly as provided rather than adding, removing or changing characters based on an assumed format.
Australia Post delivery times
Delivery times depend on the service, origin, destination and current network conditions. For domestic parcels, Australia Post lists Parcel Post at generally 2–6 business days and Express Post at generally 1–3 business days. More detailed domestic guidance gives Parcel Post estimates of 2–4 business days within the same state and 3–6 business days interstate, while Express Post is listed at 1–2+ business days within the same state and 1–3+ business days interstate.
Next-business-day Express Post is available only within Australia Post's designated next-business-day network. A shipment sent outside eligible postcode areas should therefore not be assumed to arrive the next business day simply because Express Post was selected.
For international parcels, Australia Post lists International Courier at approximately 2–3 business days, International Express at 3–6 business days and International Standard at 5–10 business days between major metropolitan areas under the stated service conditions. International Economy is substantially slower, with Economy Air generally listed at 15+ business days and Sea Mail at about 2–3 months. International Economy does not include package tracking.
Examples of international Australia Post delivery times
Australia Post publishes destination-specific estimates rather than applying one delivery time to every country. For shipments from Australia to China, the current guide lists International Courier at 3–5 business days, International Express at 3–6 business days and International Standard at 4–9 business days.
For Singapore, the guide lists International Courier at 2–3 business days, International Express at 3–5 business days and International Standard at 4–7 business days. For the United Kingdom, the corresponding estimates are 2–3 business days for Courier, 3–5 business days for Express and 4–7 business days for Standard. For the United States, Australia Post lists Courier at 2–4 business days, Express at 3–6 business days and Standard at 5–9 business days.
These international times are estimates for shipments between metro areas of major cities and generally assume low-value, low-risk items that have been pre-cleared through customs. Customs processing time is excluded, and regional locations, disruptions, flight capacity and border procedures can make actual delivery longer. Australia Post also advises adding extra transit time to international items originating in South Australia, Tasmania or the Northern Territory because they must travel interstate before leaving Australia.
How to contact Australia Post about a shipment
If your Tracking information shows a problem, Australia Post provides online enquiry forms through its Help and Support service. There is also a support chat where customers can use the chatbot or reach a live agent when available. For a parcel that is taking much longer than expected, Australia Post's online enquiry process uses the tracking number to investigate the shipment.
Customers in Australia can call Australia Post on 13 POST (13 76 78). Customers calling from overseas can use +61 3 8340 7239. You can also visit an Australia Post Post Office for assistance with suitable postal and shipment issues. Business customers using contract services may have additional support through their account manager or business support channels.
If you are the recipient of an online order, it is often useful to contact the seller or sender first, particularly when the retailer purchased the postage. The sender normally has the original lodgement receipt, shipment record and commercial details needed to start an investigation or make a claim.
Frequently asked questions about Australia Post package tracking issues
Why does my Australia Post tracking number show no result?
First check that the number was copied correctly and that the shipment is actually being handled by Australia Post. Australia Post states that a newly created number may not be recognised until the parcel receives its first scan. If the number is valid but has not yet entered the tracking system, Australia Post recommends trying it again after about 24 hours.
Why has my Australia Post Tracking not updated?
A lack of a recent scan does not always mean the package has stopped moving. Australia Post explains that parcels pass through several stages and that the public tracking status may remain unchanged while an item travels between facilities. Longer distances, weekends, busy periods and international transport can all increase the time between visible updates.
Why was my package scanned in a city that is not on the direct route?
Australia Post routes parcels through central processing centres rather than always following the geographically shortest route. Major parcel-processing locations are used to sort and redistribute shipments efficiently, so a Tracking event in another city or state can be part of the normal delivery route.
Can I Track an Australia Post package without a tracking number?
No. Australia Post states that it needs the tracking number or article ID to locate a shipment in its tracking system. A recipient's name or address cannot be used as a substitute. If you do not have the number, check the sender's confirmation email, invoice or order page, or ask the sender to provide it.
Where can I find my Australia Post tracking number?
Senders should check the Post Office receipt, shipping label, barcode or removable sticker on a prepaid satchel. Recipients can check their order confirmation, invoice, dispatch email or tracking notification. For online purchases, the retailer can normally provide the tracking number if it is not visible in the order account.
Why does my international package have a tracking number that does not end in AU?
International packages may keep the identifier assigned by the postal operator in the origin country. Australia Post's own Tracking API documentation demonstrates international identifiers such as LX123456789US. A foreign country suffix therefore does not prevent the item from later receiving Australia Post tracking events after it reaches the Australian network.
Can I Track Australia Post International Economy parcels?
Australia Post states that International Economy parcel service does not include tracking. If package tracking is important, use a service that explicitly includes Tracking, such as International Standard, International Express or International Courier, subject to availability for the destination.
Why is my international Australia Post package delayed at customs?
Customs clearance is separate from Australia Post's published transport estimates and can extend the overall delivery time. Incomplete customs information, destination-country import rules, duties, security checks or restricted goods can cause additional delays. Continue checking Tracking and contact the sender or Australia Post if the shipment remains delayed beyond the expected timeframe.
What should I do if Tracking says delivered but I cannot find the package?
Check the delivery location, safe-drop areas, collection instructions and any proof-of-delivery information available in the AusPost app or tracking page. Also check whether another household member or authorised person received the parcel. If it is still missing, use Australia Post's Help and Support options to report the delivery issue and provide the tracking number.
What should I do if an Australia Post package is much later than expected?
Compare the shipment with the expected delivery date shown in Tracking and check Australia Post's current service disruptions. If the parcel is substantially overdue, the sender should usually contact Australia Post or submit an online enquiry with the tracking number. Recipients of online purchases should also contact the retailer, because the sender may need to open the formal investigation or compensation request.
