Using Australia Post the smart way
Australia Post eParcel suits high-volume domestic parcels and Express Post fits time-sensitive orders, while small, light items are often cheaper via Aramex. ShipCay auto-picks the cheaper option by destination and weight so you don't decide order by order.

Australia Post shipping labels: what sellers ask about
Prepaid satchels vs printing your own labels
Australia Post sells prepaid satchels and postage-paid packaging: the postage is already in the price of the packaging, so nothing needs printing. That suits occasional senders. Once you ship regularly, account-based labels (MyPost Business or an eParcel contract) are usually cheaper per parcel and let you use your own boxes—you print one label per order instead of buying packaging in advance. ShipCay automates the account-based flow: every label is paid at generation, so the parcel is already postage-paid when it is lodged.
Registered Post is not the same as Parcel Post with signature
Registered Post is a letters and documents service offering proof of posting and signature on delivery—it is not a parcel service. People searching for "registered post labels" for a parcel almost always want proof of delivery, which for parcels means adding Signature on Delivery to Parcel Post or Express Post. Mixing the two up usually ends with the service being rejected at lodgement.
eParcel contract vs MyPost Business
MyPost Business is aimed at smaller senders, with rates that improve as your monthly volume moves up the bands, and you can sign up and start immediately. An eParcel contract is negotiated for higher volume and normally comes with its own rate card plus lodgement and packaging requirements. Both produce official labels; which is cheaper depends on your monthly volume and parcel profile (weight, size, destination mix). If your volume is growing, it is worth recalculating every quarter.
Label size and printing
Australia Post labels print at 4×6 in (100×150 mm) on thermal stock, or on A4 sheets to be cut and attached. The one rule that matters: print at 100% scale. Scaling or cropping to save paper deforms the barcode, and a barcode that will not scan at lodgement has to be reprinted on the spot. ShipCay merges the entire batch into a single PDF so nothing is missed or double-printed.
International parcels and customs data
International labels carry a customs declaration: an accurate goods description, quantity and declared value, and for many destinations an HS code plus sender and recipient phone numbers. Vague descriptions such as "gift" or "sample" are the most common reason parcels are held or returned. ShipCay carries the declaration fields from the order onto the label, so you are not re-keying them in a carrier portal.
Where Australia Post costs actually go up
Three things quietly eat margin: cubic (volumetric) weight on large, light parcels, which are priced on volume rather than actual weight; remote-area and fuel-linked surcharges; and re-labelling caused by bad addresses. So do not assume Australia Post is always cheapest for small items—Aramex frequently comes in lower on light cross-border parcels, which is exactly why per-order comparison beats a fixed default carrier.

How do I print Australia Post shipping labels myself?

What's the difference between Parcel Post and Express Post labels?

Can I use prepaid satchels instead of printing labels?
