You can send a 25kg parcel anywhere in Australia, but not with every service. Many standard post products stop at around 22kg, so a 25kg box usually needs a courier or freight service that accepts it. The price then depends on the greater of two numbers: the parcel’s actual weight and its cubic (volume-based) weight. Below is how to check both, pack the box, and compare options without being caught by surcharges.
TL;DR
- 25kg is over the limit of standard postal parcel products (about 22kg), so book a courier that explicitly accepts up to 25kg.
- You pay for the higher of actual weight or cubic weight, so measure the box as carefully as you weigh it.
- Compare the total price: fuel surcharges, handling fees, residential and remote-area charges can change the cheapest option.
- Pack for a heavy load: double-wall carton, no empty space, strong tape, and a label on the top and inside.
- Aeros Couriers lets you compare rates for parcels up to 25kg in one place and book door-to-door pickup with tracking.

Can you send 25kg in one parcel?
Yes, with the right service. The national postal service’s parcel products cap out lower: published limits are 22kg, 105cm on the longest side and 0.25 cubic metres. A 25kg parcel is 3kg over that, so it needs a different channel.
Your realistic options are:
- A courier that takes parcels up to 25kg. This is the sweet spot for most heavy boxes: books online, collects from your door, and delivers to the door.
- Splitting the load into two parcels. Sometimes cheaper, sometimes not. Two 12.5kg boxes each carry their own base charge, so price both ways before you decide.
- Freight. Worth considering once you pass 25kg, ship several heavy cartons, or send a pallet. A single 25kg box rarely needs it.
Our parcel delivery service covers Australia-wide parcels up to 25kg, and our freight option is there when the load outgrows a parcel.
What decides the price of a heavy parcel
Four things drive the price of a 25kg parcel. Know them and the quotes stop being mysterious.
1. Weight: actual or cubic, whichever is higher
Couriers charge on the greater of actual weight and cubic weight. Cubic weight converts the space your box takes up into a notional weight, because a bulky light parcel uses as much truck space as a dense heavy one. Multipliers differ between carriers, and the common divisors and factors are explained in our guide to Australia’s cubic weight formula.
A worked example using the 250 kg per cubic metre factor that some carriers use. A box measuring 60 x 40 x 40cm is 0.096 cubic metres. Multiply by 250 and the cubic weight is 24kg. If the box weighs 25kg, you are charged for 25kg. If you instead used a 80 x 50 x 50cm box (0.2 cubic metres), cubic weight becomes 50kg, and you pay for 50kg even though the contents weigh 25kg. The lesson: the smaller the box that safely holds your goods, the lower the bill.
2. Distance and zone
Metro to metro is usually the cheapest. Sending from Sydney to Perth, or into regional and remote postcodes, costs more because of the distance and the extra handling at the other end.
3. Speed
Standard, express, same day and air options sit at different price points. If the parcel is not urgent, standard is almost always the cheapest. If it must arrive tomorrow, price express and compare it with the cost of a missed deadline. Our express courier service page explains what that looks like for boxes and parcels.
4. Add-ons and surcharges
Fuel levies, handling fees, residential delivery fees, signature on delivery and insurance can each add to the base rate. This is where quotes that look cheap often stop being cheap. We cover typical charges in Australia’s courier prices explained and in our look at 25kg parcels and hidden fees on express delivery.
How to pack a 25kg parcel so it arrives intact
A heavy box takes more punishment than a light one: it is stacked under other parcels, dropped onto conveyors and carried by one person. Pack it with that in mind.
- Use a strong carton. Choose double-wall corrugated cardboard rated for the weight. A box that bows when you lift it will fail in the network. Do not reuse a tired box that has been wet or crushed.
- Match the box to the contents. Too big and you pay for cubic weight and need more filler. Too small and the corners burst. Aim for 5cm of cushioning on every side for fragile items.
- Fill every gap. Empty space lets contents shift, and a shifting 25kg mass punches through cardboard. Use paper, air pillows or foam so nothing moves when you shake the sealed box.
- Spread the weight. Put the heaviest items at the bottom and centre. Never let a single dense object sit against a wall of the box.
- Tape it properly. Apply three strips across each seam, top and bottom (the H-pattern), using wide packing tape rather than masking tape.
- Label twice. Attach the printed label on the largest face, keep it flat and unobscured, and put a second copy with the address inside the box in case the outer label is damaged.
- Add handles or mark it heavy. If the box has hand holes, check they will not tear. Writing the weight on the side helps the person lifting it.
Photograph the sealed box and the label before pickup. If there is ever a claim, you will have proof of how it left you.
Weight and size restrictions to check first
Before booking, confirm these with the carrier:
- Maximum weight and longest side. A courier that accepts 25kg may still set a limit on length, so measure all three dimensions.
- Prohibited and restricted goods. Dangerous goods, batteries, aerosols, liquids and some chemicals are commonly restricted or need special handling. If your parcel contains any, check the terms before you book rather than after.
- Delivery address type. Residential, business, PO box and remote addresses are treated differently. Many couriers cannot deliver to a PO box at all.
- Insurance limits. Check what is covered and what the maximum value is. If your goods are worth more, consider additional cover.
This takes five minutes and prevents the most frustrating outcome: a parcel returned or held after you have already paid.
How long does heavy parcel delivery take?
Transit time depends mostly on the route and service level, not the weight. Metro-to-metro standard parcels often arrive in a few business days, interstate and regional deliveries take longer, and remote areas longer again. Express and same-day options exist for urgent jobs within the coverage the carrier lists. Always read the estimated delivery window on the quote, and allow extra time around public holidays and sale periods when networks are busy.
Two practical points for heavy parcels:
- Pickup. Book door-to-door collection if you can. Carrying 25kg to a depot and queueing is a real cost in time and back strain. Make sure someone is available at the pickup address, with the parcel ready and labelled.
- Tracking. Use a service that gives you tracking from pickup to delivery, so you can tell the recipient when to expect it. A heavy parcel left on a porch is a bigger risk than a light one, so consider requiring a signature when the contents are valuable.
Perspective: what we see in heavy parcels
Most of the frustration we hear about from people sending a heavy box is not the base price. It is the extra lines that appear afterwards: a fuel levy, a handling fee, a charge for a box that turned out larger than declared. A quote is only useful if it is the price you actually pay.
That is why we built Aeros Couriers around transparent flat-rate pricing with no hidden fees such as fuel surcharges or handling costs, and around comparing rates from major carriers in one place so you are not opening five tabs. Our advice for any 25kg parcel is simple: measure the box accurately, compare the all-in price rather than the headline price, choose the slowest service that still meets your deadline, and pack as though the box will be dropped once.
For small businesses, the savings compound. Heavy orders go out every week, so a few dollars per parcel matters, and a rewards program that turns bookings into further discounts helps. For individuals sending something heavy once, the priority is certainty: a clear price, pickup from your door, and a person you can reach if something goes wrong.

How to compare 25kg courier services
The cheapest-looking quote is not always the cheapest service. Compare on these criteria, in this order.
| Criterion | What to check | Why it matters |
|---|---|---|
| All-in price | Base rate plus fuel, handling, residential and remote fees | Headline rates often leave these out |
| Weight basis | Actual or cubic weight, and the multiplier used | A bulky box can be billed far above its real weight |
| Maximum size | Weight, longest side and volume limits | A 25kg limit may come with a length limit |
| Speed | Estimated delivery window and service level | Cheaper services may be slower |
| Pickup | Door-to-door collection or drop-off only | Saves time and carrying |
| Tracking | Scan events from pickup to delivery | Lets you manage the recipient’s expectations |
| Insurance | Included cover, limit and claim process | Matters for valuable or fragile goods |
| Support | A person you can reach, and how quickly | Heavy parcel problems need fast answers |
Two habits make the comparison much easier. First, enter the same weight and dimensions every time, so every quote is based on the same parcel. Second, compare totals at the checkout stage, not the first price displayed.

Ways to bring the cost down
- Right-size the box. Cutting cubic weight is the most reliable saving.
- Choose standard over express when the deadline allows.
- Send to a business address where possible, since residential delivery can attract extra fees with some carriers.
- Batch shipments. If you send several heavy parcels, bulk rates and rewards can reduce the per-parcel cost.
- Book early. Last-minute bookings push you toward express pricing.
Common mistakes with heavy parcels
- Guessing the weight. Use bathroom or luggage scales and weigh the packed box, not just the contents.
- Ignoring dimensions. Many people check weight and forget that volume sets the price.
- Reusing old labels. An old barcode can send the parcel to the wrong place. Remove or cover it fully.
- Skipping insurance on valuable goods. Check whether included cover is enough for the item’s value.
- Leaving the recipient uninformed. Send the tracking link so someone is home to receive a 25kg box.
FAQ
How much does it cost to send a 25kg parcel in Australia?
The price varies with distance, speed, box size and add-on fees, so there is no single figure. Metro-to-metro standard delivery is typically the cheapest, and remote or express deliveries cost more. Enter your exact weight and dimensions into a comparison tool to see the all-in price before you book.
Can I send 25kg with the post office?
Standard postal parcel products are limited to 22kg, so a 25kg parcel is over the limit. You would need to split it into two parcels or use a courier that accepts up to 25kg. Check the current limits on the postal service’s own site before relying on them.
What is the cheapest way to send a heavy parcel?
Pack it in the smallest strong box that fits, choose a standard service, and compare all-in prices across carriers. Watch for surcharges, because a low base rate can end up costing more than a flat all-inclusive one.
Do I need insurance for a 25kg parcel?
It depends on what is inside. If the goods would be costly to replace, check the included cover and its limit, and add more if needed. Photograph the packed parcel before pickup in case you need to claim.
Can someone collect the parcel from my home?
Yes, door-to-door pickup is available through online courier platforms, including ours. Have the parcel sealed, labelled and ready, and make sure someone is there at the agreed time.
