To use Australia Post OnDemand, you’ll need to generate an API key.

You do not need an eParcel or StarTrack account to access these services, although having one may help speed up the setup process. For assistance, contact your Australia Post Account Manager.


Available OnDemand Services

The following delivery options are supported:

  • Evening Delivery
    Same-day delivery within local metro areas during the evening

  • Saturday Delivery
    Delivery within the same metro area between 1pm–6pm on Saturdays

  • Now 3Hr Delivery
    Same-day delivery within 3–4 hours in local metro areas

For the latest delivery zone availability, refer to Australia Post’s current zone information.
