- 1 Next business day delivery is only available within the Express Post next business day delivery network. For more information visit auspost.com.au/expresspostnetwork. The national next business day delivery network operates between capital cities (excluding Darwin; and for Perth between CBDs only) and some major centres.
- 2 Rigid or inflexible items such keys, pens, USBs or CDs should never be sent in a regular paper envelope as they could easily be damaged by our sorting equipment or torn from the envelope and lost. Items like these should always be packaged correctly and sent as a parcel. View our packaging hints and tips and domestic parcels.
