Australia Post is one of the most popular shipping carriers for WooCommerce stores in Australia. It helps merchants offer accurate shipping rates, print shipping labels, and provide tracking information to customers.
However, Australia Post Shipping Issues can sometimes occur. Customers may see incorrect shipping rates, labels may fail to generate, tracking information may not update, or Australia Post services may not appear at checkout.
These issues can lead to delayed orders, frustrated customers, and lost sales.
The good news is that most Australia Post shipping issues in WooCommerce can be fixed with a few troubleshooting steps. In this guide, we will look at the most common Australia Post Shipping Issues and how to solve them.

One of the biggest Australia Post Shipping Issues is incorrect product data. This is especially important for WooCommerce stores that depend on Australia Post for order fulfillment.
According to Australia Post, the carrier delivered more than 2.2 billion items across Australia during FY2025, highlighting the need for accurate product weights, dimensions, and shipping configurations to ensure reliable rate calculations and smooth deliveries.
Australia Post calculates rates based on:
- Weight
- Length
- Width
- Height
- Shipping destination
If any of these values are missing, the WooCommerce shipping plugin may not return shipping rates.
What to Check
Navigate to:
WooCommerce → Products
Open each product and verify:
- Weight is entered correctly
- Length is entered
- Width is entered
- Height is entered
Even a small mistake can affect shipping calculations.
For example, entering kilograms instead of grams can result in extremely high shipping charges. Missing dimensions can also prevent Australia Post from returning valid rates.

- MyPost Business credentials
- StarTrack account details
- API authentication information

Shipping zones determine where shipping methods appear.
If Australia Post rates are not showing for customers, the shipping zone configuration may be incorrect.
What to Check
Go to:
WooCommerce → Settings → Shipping → Shipping Zones
Verify that:
- Australia Post shipping methods are assigned to the correct zones
- Customer locations match the zone settings
- No overlapping zones are causing conflicts
A common Australia Post Shipping Issue is assigning Australia Post services only to selected regions while customers are placing orders from locations outside those zones.

If the API connection fails, rates may not appear.

Check:
- Store address
- City
- State
- Postcode
- Country
Ensure these details match your actual shipping location in your WooCommerce shipping plugin.

- Shipment creation was successful
- Tracking functionality is enabled
- API credentials remain active
