Rates discrepancy
If the Australia Post shipping rates displayed in your WooCommerce checkout do not match the official Australia Post prices, use the steps below to confirm and troubleshoot the issue.
The best way to confirm is by checking the official Australia Post Postage Calculator.
How to verify rates with the Australia Post Calculator?
- Go to: https://auspost.com.au/parcels-mail/calculate-postage-delivery-times/#/
- Log in to your Australia Post account.
- Recreate the shipment using the same data as in WooCommerce – destination, package size, weight, and service type.
- Compare the result with the WooCommerce shipping rate.
Tip: All carrier calculators, including Australia Post, provide estimates. Small discrepancies of around 10–15% can occur due to rounding or slight variations in how parcels are measured.
Troubleshooting
If the differences remain noticeable, review the plugin setting that can directly affect the returned rates:
- Goods and Services Tax (GST): You can enable or disable the inclusion of GST 10% in shipping costs. Adjusting this option ensures that the rates shown at checkout are consistent with your tax setup.
Still Seeing Issues?
If, after these checks, the discrepancies are still significant, please contact our support team. Provide detailed shipment information (origin, destination, dimensions, weight, and chosen service), so we can reproduce and investigate the issue.
