The same tower box that clears Canada's line misses Australia's by a single inch.
A tighter line than the rest of this site quotes
USPS's Individual Country Listing for Australia, read on pe.usps.com 2026-08-21, sets Priority Mail International's limits at a maximum weight of 66 lb, a maximum length of 42 inches, and a maximum combined length and girth of 97 inches. The length figure alone is stricter than most destinations this site has checked: Australia's 42-inch ceiling is well under Canada's 59-inch length limit on the same product, even though the two countries share the same 108-inch combined length-and-girth figure.
| Measurement | Desktop tower box | USPS limit to Australia | Where it lands |
|---|---|---|---|
| Length | 26 in | 42 in | Clear |
| Length plus girth 26 + 2×(22+14) | 98 in | 97 in | 1 in over |
| Weight | 30 lb | 66 lb | Clear |
Weight and length both clear with room left over; the combined figure is the one that bites, and by a single inch. Trim the box on its shorter sides rather than its length and the arithmetic moves fast: a 24 × 20 × 14 in carton around the same tower comes to 24 plus twice (20 plus 14), or 92 inches of length and girth, five inches under Australia's line. A snugger fit on the width and height, not a shorter tower, is what actually closes the gap.
No lithium battery to declare
A laptop headed overseas drags along one extra complication a tower never has to deal with: an installed lithium-ion battery, regulated as UN3481, with its own carrier mark and a spot on the customs form. A desktop runs off the wall, not a cell, so none of that battery paperwork attaches to a shipment like the one quoted on this page — to Australia or anywhere else.
What still applies
Ordinary customs and export rules for electronics still apply to a tower the same as any other commodity — a commercial invoice, an accurate description, and an honest declared value.
What doesn't
The lithium battery mark, the IATA Section II watt-hour and quantity limits, and the carrier's dangerous-goods surcharge that a laptop or a spare battery pack can trigger. A tower skips all three.
Packing material, not the tower
USPS's Australia listing, read the same day, restricts raw plant material used as packing filler — straw and the like — separately from anything about electronics. Foam, air pillows and paper padding are unaffected; it is worth knowing before anyone improvises with what is on hand.
What FedEx wants on the box once it crosses the Pacific
FedEx's customs documentation page, read on fedex.com 2026-08-21, states that “the Commercial Invoice is required for all international commodity shipments” and calls it the foundation every other international shipping document is built from. The page's own instruction is that the information on it has to be thorough and accurate, not a rough description filled in at the counter.
A used machine's value is its used value
Declare the fair resale price of the tower, not what it cost new. A vague or inflated figure is a more common hold-up at an Australian border than an honest one.
Consistency beats precision
The same description, in the same words, on the commercial invoice, the label and any other paperwork is what keeps a shipment from getting pulled for a second look.
Name it specifically
“Used desktop computer, HP Pavilion tower, no monitor” tells a customs officer what to expect. “Electronics” or “computer parts” invites the question instead of answering it.
A Pacific-gateway leg, quoted live
A computer headed to Australia can move in a single checkout booking here now; the two-booking relay remains the alternative — an ordinary domestic parcel to a US address near a Pacific gateway, then a separate international booking from there, whether that is USPS Priority Mail International bought directly, a carrier's own international account, or a freight forwarder. We quoted that relay's first leg: the same HP Pavilion tower from the size check above, Berkeley Heights, NJ to a Los Angeles, CA ZIP, captured live on 2026-08-21.
What we typed

Both ZIPs live at request time. This is the domestic leg only, not a Pacific crossing.
| Carrier | Service | Price | Estimated transit |

| UPS | Ground | $78.91 | 6-7 business days |
| FedEx | Ground Economy | $92.28 | 9-10 business days |
| UPS | Ground Saver | $102.54 | 6 business days |
| FedEx | Ground | $121.63 | 6-7 business days |
| UPS | 3 Day Select | $140.18 | 4-5 business days |
This is not an Australia price and it does not get the tower across the Pacific by itself — it is the domestic lane SMKlog can quote, shown so the two-booking model has a real number attached rather than a guess. Because this exact box runs an inch over Australia's own combined-size line, the practical next step is repacking a shade tighter on width and height before the international leg is booked, not after.

Common questions
Can you ship a computer to Australia?
Yes, on a carrier's own international product — or at SMKlog's checkout, which now sells the Australia lane with the customs declaration completed before payment. A desktop tower carries no lithium battery to hold it back; a laptop does, and battery items go to review rather than the online lane. What follows is what we can honestly tell you about the trip.
Does a desktop computer clear Australia's own size limit?
Barely not, on the box we tested. USPS's Priority Mail International listing for Australia, read 2026-08-21, caps combined length and girth at 97 inches. A 26 x 22 x 14 in tower box works out to 98 inches by that formula — one inch over, on a box that clears Canada's 108-inch line on the same site's general computer-shipping page with room to spare.
Does a desktop tower need a lithium battery declaration for Australia?
No. That requirement belongs to laptops, whose battery is installed and regulated as UN3481. A desktop tower runs on wall power and carries no lithium battery pack of its own, so the battery paperwork that complicates an international laptop shipment does not apply to it here either.
What does FedEx want on the customs paperwork for Australia?
A Commercial Invoice, which FedEx's own page states is required for all international commodity shipments, read 2026-08-21. It asks for a description thorough and accurate enough to stand on its own: what the item is, how many there are, what it is made from, and its declared value.
What can SMKlog actually price for an Australia-bound computer shipment?
Both legs now. The crossing prices live at checkout with Australia as the destination — size permitting, since this box runs an inch over USPS's own line — while the domestic leg to a Los Angeles, CA ZIP near the Pacific gateway many forwarders use quoted $78.91 to $140.18 across carriers on 2026-08-21, with the onward booking through a carrier's international service or a forwarder.
