Sendle — how delivery works

• ATL by default: parcels can be left without signature if the driver finds a safe place.
• If there’s no safe place: you’ll see an “Unable to deliver” status; please use the tracking link to book a redelivery.
• PO Boxes/Parcel Lockers: not supported — choose an AusPost option if you need those.

Australia Post — Standard

• Safe Drop: if ATL is allowed and there’s a safe place, AusPost may leave the parcel.
• If no safe place: a card is left and your parcel goes to a nearby Post Office for collection (held ~10 business days).
• Parcel Lockers/Collect: available via a free MyPost account.

Australia Post — Express

• Fastest option: Next business day within the official Express Post network (origin/destination dependent).
• Outside the network: delivered by the fastest possible service.
• Safe Drop & collection: same rules as Standard.
