Authority to Leave (ATL)
Authority to Leave (ATL) is a service offered by Australia Post that allows your parcel to be delivered without requiring a signature or someone to be present at the time of delivery.
If you choose to enable ATL, the delivery driver will leave your parcel in a safe location at your address.
If no suitable safe place is found, your parcel will be taken to the nearest post office for collection.
