An unexpected delivery charge can turn a good online bargain into an expensive order. Shipping may be recalculated after checkout because of parcel size, destination, insurance, or a rural delivery surcharge. If the amount charged is higher than the quoted or agreed price, you may be entitled to have the difference returned.
This commonly happens with Australia Post, courier brokers, marketplace sellers, and independent online shops. A retailer might charge for express delivery but send the parcel by standard post, or apply two shipping fees when several items were packed together.
Keep the order confirmation, tax invoice, tracking information, and payment record. These documents make it much easier to show what you were promised and what was actually taken from your card or PayPal account.
Shipping costs can also be hidden in the final checkout screen, especially when buying several items such as school lunch supplies. Checking the delivery line before paying is useful, but it does not remove a seller’s responsibility to correct a genuine overcharge.
| Situation | First contact | Likely remedy |
|---|---|---|
| Charged twice for one delivery | Retailer or marketplace | Refund of the duplicate fee |
| Paid for express, received standard | Retailer or carrier | Refund of the upgrade or price difference |
| Quoted shipping changed at checkout | Seller | Review of the advertised price |
| Parcel returned or cancelled | Seller or carrier | Refund of unused postage, subject to terms |
| Carrier billed more than the approved label | Shipping platform | Billing adjustment or account credit |
Start by comparing the advertised delivery price, checkout total, invoice, and payment receipt. Look for separate lines covering postage, handling, insurance, fuel levies, signature-on-delivery fees, or a remote-area surcharge. A difference of a few dollars may be GST rounding, while a much larger gap needs a clear explanation.
Check whether the seller promised Australia Post Parcel Post, Express Post, a courier service, or a particular delivery window. The service selected matters. If you paid for Express Post but the tracking record shows ordinary Parcel Post, save screenshots of both the offer and the tracking history.
Take a screenshot of the order confirmation and note the date, order number, delivery address, amount charged, and amount you believe should have applied. Include the parcel label if it shows a cheaper service, a different weight, or a sender-paid label.
For a business account, compare the carrier invoice with the shipping label and the parcel’s actual dimensions. Dimensional weight can create a legitimate adjustment, but the carrier should be able to explain how it was calculated. A clear record also helps if a retailer says the courier, rather than the shop, is responsible.
Contact the retailer first unless the overcharge came directly from your Australia Post, courier, or shipping-platform account. Use email, a website form, or live chat so there is a written trail. State the amount charged, the amount expected, and the refund you are requesting.
Keep the message factual: “I was charged $24.95 for delivery, while the checkout confirmation showed $14.95. Please refund the $10 difference to the original payment method.” Ask for a response within a reasonable business period and avoid accepting store credit if you require money returned.
If you manage an online shop, update the delivery policy after resolving the dispute through the site admin login. Make sure metro, regional, PO Box, and Parcel Locker prices are described accurately.
Under the Australian Consumer Law, services must generally be provided with due care and skill and within a reasonable time when no timeframe was agreed. A retailer also should not mislead customers about the total price or delivery method. These principles can support a refund request when the seller charged for a service that was not supplied.
The seller may still have a valid reason for a revised shipping price if the original quote clearly said it was an estimate, the address was changed, or the parcel’s size and weight were entered incorrectly by the customer. Ask for the calculation rather than assuming every adjustment is unlawful.
If the business refuses to help, lodge a complaint with your state or territory consumer affairs agency. You can also ask your bank about a card dispute or chargeback, although this should generally follow a genuine attempt to resolve the matter with the merchant.
Before paying, check whether postage is charged per item, per order, or by weight. Combining products into one parcel may reduce the total, while separate sellers on a marketplace will usually charge separate delivery fees. Confirm that an advertised “free shipping” offer applies to your postcode and basket value.
For regular parcels, compare Australia Post rates with a reputable courier broker and weigh packages at home. Keep in mind that regional and remote Australian addresses may cost more, and delivery times can change around public holidays. A postie’s tracking scan does not prove that the premium service you paid for was used.
Save invoices until the goods arrive and the delivery service has been verified. If a refund is approved, check your bank statement rather than relying only on a confirmation email. Take action promptly, document every contact, and request the shipping difference in clear dollar terms.
