Firstly ask if anyone in your household brought it in - it happens! If not, then contact your local Australia Post office with your tracking number and ask them to locate it for you. If left as a safe drop they are required to provide you with a photograph of where they left it. Often they are meant to be carded but do not and it will be safely kept at the post office for you. If not collected for a couple of weeks they will return it to us.If this occurs we are happy to send it back to you, but there will be an additional postal cost, this can be claimed by you directly from Australia Post.
