How to track SingPost (`...SG`) Speedpost and registered parcels handed off to Australia Post

Singapore Post (SingPost) serves as both Singapore's national post and a major APAC air transshipment hub at Changi Airport (`SIN`), flying `EX...SG`, `CP...SG`, `LP...SG`, and `RF...SG` shipments into Sydney (`SYD`), Melbourne (`MEL`), Brisbane (`BNE`), and Perth (`PER`) for Australia Post delivery.

How the SingPost → Australia Post handoff works

Follow the parcel across both networks without waiting on asynchronous webhooks or losing visibility at the handoff boundary.

1. SingPost Changi (`SIN`) Processing & Despatch
SingPost sorts the parcel at Changi Airfreight Centre in Singapore (`Despatched to overseas` — Country code: `AU`) and loads it onto a direct flight to Australia.
2. Arrival in Sydney, Melbourne, Brisbane, or Perth
Australia Post scans `Arrived awaiting clearance (Inbound)` at the Australian International Gateway and clears ABF customs and DAFF biosecurity.
3. Australia Post Final Delivery
Australia Post delivers the parcel across Australia under the same 13-character `...SG` barcode and syncs notifications to the MyPost app.

Singapore Post (SingPost) Speedpost & ePac to Australia Post Handoff FAQ

Because Singapore Changi (`SIN`) has frequent daily direct flights to Sydney, Melbourne, Brisbane, and Perth, SingPost Speedpost (`E...SG`) takes 3 to 6 business days and ePac/Registered (`LP...SG` / `RF...SG`) takes 5 to 10 business days.
Why does my AliExpress or 4PX order have a Singapore Post (...SG) tracking number?
4PX and Cainiao use SingPost as a premier transshipment air hub for Australia-bound parcels (especially electronics with lithium-ion batteries).
Does my ...SG tracking number work in the AusPost app?
Yes—enter the 13-character `...SG` number directly in the Australia Post app or track both SingPost and AusPost scans together on `lastscanned`.
