A quick overview before you dive in:
If courier prices have felt higher in 2026, fuel surcharges are likely part of the reason. A fuel surcharge is an extra percentage couriers add to cover fuel costs, and it can change every month. Australia Post's published surcharge, for example, ranged from 4.8% in early April 2026 to 19.5% in June. The practical answer for senders is to compare the all-in price, not the base rate.
Here's how fuel surcharges work, why they move, and what you can do about them.
A fuel surcharge, sometimes called a fuel levy, is an extra charge couriers add to cover the cost of fuel. Instead of changing their base rates every time fuel prices move, couriers generally keep the base rate steady and adjust a separate surcharge, usually shown as a percentage. That way the price can follow fuel costs up or down without a full price review.
Each courier sets its own surcharge and decides how and when to change it, so two couriers can apply very different surcharges in the same month.
Fuel surcharges are reviewed regularly to keep up with fuel prices. Australia Post, for example, describes its surcharge as an estimate of its direct and indirect fuel costs, based on current fuel prices, published 30 days in advance. It says the surcharge can rise, fall or not be applied at all.
Australia Post's published surcharge shows how much these rates moved in 2026:
| Month | Surcharge |
|---|---|
| January | 6.2% |
| February | 6.7% |
| March | 5.2% |
| April (1 to 22 April) | 4.8% |
| 23 April to 31 May | 12.0% |
| June | 19.5% |
| July | 12.3% |
| August | 9.9% |
| September | 6.9% |
| October | 11.5% |
| November | 13.5% |
| December | 14.0% |
These are the rates on Australia Post's business shipping pages, checked on 10 November 2026. Other couriers publish their own, and they don't move in step.
Because the surcharge is a percentage, its effect grows with the price. As a simple example, on a delivery with a $40 base charge:
That's a difference of almost $6 on the same delivery, purely from the month it was sent. For a business sending many parcels a week, those differences add up quickly. (The $40 figure is for illustration only, not a real quote, and couriers apply surcharges to their own charges in their own way.)
A courier's headline rate often leaves out the fuel surcharge and other fees, so comparing base rates can be misleading. A courier with a lower base rate but a higher surcharge can end up costing more.
When you compare couriers with Pacer Logistics, each price is shown in Australian dollars including GST, fuel and fees, so you're comparing the real totals side by side. The price can still change if your shipment details change during booking, or if the courier finds the size or weight doesn't match what you entered.
Other things can change what you pay, too:
Australia Post's prices also rose on 1 July 2026. Our guide to courier vs Australia Post covers that change and when each option tends to suit.

Fuel surcharges aren't going away, and they'll keep moving with fuel prices. The simplest protection is to compare all-in prices from several couriers each time you book.
