When you purchase an item that includes Australia Post International tracking or you take an item to an Australia Post office and purchase international tracking then you will receive a tracking number, this can normally be found on your sales receipt or a confirmation email sent to you. These are normally 13 digits long and contain a combination of letters and numbers, for example, they will always start with 2 letters followed by 9 numerical digits and end in an AU, here is one example JD 123456789 AU. Once you have this number you will be able to go to Australia Post and input it into the tracker to find out where your parcel is, using the Australia Post tracker you may find that the information is not always 100% up to date and you will have to do some more chasing on your side to determine where your parcel may be, to avoid this you can use Ship24s free to use "multi-track" system, here you can input up to 10 different tracking numbers no matter how many different couriers are being used or how many countries they might be passing through, one added benefit of using Ship24s system is that you will have "real-time" information to hand about where your parcel is and who is in control of it, for example, if it is held up by a customs department somewhere in the world, you will find that the system will be updated accordingly and you will even have the contact information relating to who has your package, with the time it was seen. You may see that on the tracking search it has multiple updates from the same courier in the same place for example if a package is at a sorting house then you may see 5 different "sorting house" updates at various times, this is normal it just means that your parcel may have been given to a different part of the sorting office to make its way to the truck to transport to you. This service is available 24 hours a day, 7 days a week and can be accessed from your computer, smartphone or tablet.
