Australia Post eParcel vs Express Post: how to bulk-print labels

For shipments within Australia, sellers rely on two Australia Post services: eParcel (high-volume domestic parcels) and Express Post (fast delivery). For both, sellers often still create and download each label one by one on the carrier site—which does not hold up as volume grows.

When to use eParcel vs Express Post

eParcel is built for merchants shipping high-volume domestic parcels at better rates, while Express Post is faster and suits orders sensitive to delivery speed. Picking the right service saves money—but printing labels one by one for either is slow, which is exactly what a batch tool solves.
