Whether you are sending one package or several changes the arithmetic more than most senders expect, because almost all of the cost sits in the consignment rather than in the kilogram. The cheapest published figure for Australia in this record is 11.10 pounds, the lowest of five services Parcel2Go prices on its Australia page. Two boxes at that level is not one price doubled in any useful sense, and consolidating is usually the single largest saving available on this route.
One box or several, and why consolidation wins
Each package you send to Australia carries its own base charge, its own fuel and handling components and its own customs line. Combining two moderate boxes into one larger one removes a whole set of those fixed charges, and it usually beats the extra volumetric weight the bigger box creates. The exception is when consolidating pushes the single box past a service's maximum dimension or weight, at which point it leaves the parcel network entirely and gets quoted as freight, which is a different and generally dearer product for anything under about thirty kilograms.
What the published price covers and where it stops
Parcel2Go's Australia page priced five named services on the day it was read, the cheapest at 11.10 pounds, for the default parcel that page quotes. That is a per-consignment figure for one box. Royal Mail publishes no per-country international page, only zones, and Parcelforce's Australia directory page carries service and customs information with no price. So for multiple packages there is no published multi-item rate anywhere in this record; you price each consignment and compare against the consolidated alternative.
Volumetric weight is what actually sets the band
Shipping a box to Australia is charged on the greater of what it weighs and what its volume implies, using the carrier's divisor. This is why a box of bedding and a box of books can be quoted the same despite a large difference on the scales, and why the advice to pack smaller is not a platitude on this route. Before booking anything, measure the packed box rather than the contents, and check whether removing a few centimetres from the longest side moves you into a lower band. On long-haul routes it frequently does.
Customs for multiple packages
Each package needs its own declaration, and splitting one order across several boxes does not divide the customs value in a way that helps. Australia assesses duty and GST above its own threshold on the goods, and consignments despatched together to the same recipient can be treated as one for that purpose. Declare each box honestly, describe the contents specifically rather than as goods, and warn the recipient that charges plus a carrier handling fee may be payable before delivery.
Questions people ask about send package to australia
Is it cheaper to send one big package or several small ones to Australia?
Usually one larger consignment, because most of the cost is per consignment rather than per kilogram. The exception is when the combined box exceeds a service's maximum size or weight and has to be quoted as freight instead.
How much does it cost to send a package to Australia?
The lowest published figure in this record is 11.10 pounds, the cheapest of five services Parcel2Go prices on its Australia page, read on 10 September 2026, for the parcel that page quotes by default.
Does each box need its own customs declaration?
Yes. Each package carries its own declaration, and boxes sent together to the same recipient may still be assessed as a single consignment for duty and GST.
What is the maximum size I can ship to Australia as a parcel?
It varies by service rather than by destination. Past a service's maximum dimension or weight the shipment leaves the parcel network and is quoted as freight, which is normally dearer for anything under about thirty kilograms.
