Authority to Leave (ATL)
An instruction left with the carrier allowing them to leave a parcel at the delivery address without a signature. Common in Australian online retail — buyers enable it via Australia Post's app or account settings. Useful for sellers because it reduces failed delivery attempts and buyer frustration. Risk: the parcel can be stolen from the door. As a seller, you're generally not liable if the buyer set their own ATL and the parcel goes missing.
