Box-Packing

↑ Back to top

The box packer included with this shipping method lets you group items into packages of which you define the height, width, length, weight and max weight. The packing is mainly volume based, but does also consider item sizes too.

Setting up box sizes

↑ Back to top

Within the settings, look for the boxes setting. Click ‘add box’ to set up the boxes dimensions:

Outer dimensions are used for parcel dimensions and are passed to the API.

Inner dimensions are used for packing, and items will be fit within these.

Weight of box is the weight of the actual box, and will be added to the weight of the contents.

Max weight is the maximum weight your box can hold. This includes contents weight and box weight.

Type: This checkbox determines whether your package is a box, envelope, packet, or tube.

How the calculation works

↑ Back to top

The packer does the following:

1. Finds boxes which fit the items being packed (uses H x W x D).
2. Packs all fitting items into boxes (using volume).
3. The largest box which fits 100% of items is used *or* use the highest % packed box, and then pass unpacked items back (and repeat the process)
4. Unpackable items are packed alone, using the item dimensions.
5. All packed boxes are returned.

Satchel Rates

↑ Back to top

Satchel Rates are flat rates that you can use, instead of defining box sizes. If Satchel Rates are enabled on your site, then items are calculated based on one of three satchels available:

• 500g satchels are 335mm x 220mm ( W x H ) and are suitable for shipping CDs, iPods, mobile phones.
• 1kg satchels are 385 x 265mm ( W x H ).
• 3kg satchels are 405mm x 310mm ( W x H ) and are suitable for Fashion, books, digital cameras, toys.
• 5kg satchels are 510 x 435mm ( W x H ).

There are three options regarding the Satchel Rates dropdown:

• Enable Satchel Rates – Uses the above satchels to calculate shipping, which ignores your custom boxes.
• Prioritize Satchel Rates – Uses Satchel Rates when applicable, but if your item does not meet criteria or fit in the satchel box, it will use a custom box size.
• Disable Satchel Rates – Ignores Satchel Rates and uses your own boxes.

If you don’t intend to use the pre-defined satchels and want to use your own box sizes for the calculator, you need to select the option Disable Satchel Rates.

Services

↑ Back to top

In the Services section of the menu, you can choose which Australia Post services you want your customers to receive.

There are a few fields to note:

• Extra Cover is an optional selection that will increase the price of your shipping by adding additional insurance during transfer.
• Signature / Registered is another optional selection to cover tracking and (if purchased) signature at delivery.
• The Adjustment fields increase shipping by a flat amount or percent. A blank field leaves rates untouched.
  • i.e. Your shipping is $10 with $5 in Adjustment ($) – the customer will be charged $15 for shipping.
  • i.e. Your shipping is $10 with %15 in Adjustment (%) – the customer will be charged $11.50 for shipping.

Customer Usage

↑ Back to top

Customers will get quotes (after inputting their address) from two places:

• Cart page – by using the shipping calculator
• Checkout page – by filling in the shipping and billing forms

Troubleshooting

↑ Back to top

No rates returned/no rates available

↑ Back to top

• Ensure your API credentials are correct.
• Enable development mode, or turn on WP_DEBUG to see debugging information on the cart page. This will often reveal the problem.
• Check your products have sizes and weights set – without this the calculation cannot be performed.
• Check your store’s base country is Australia and that your using Australian Dollars (from WooCommerce > Settings > General).

Error message in cart: Fatal error: Cannot use object of type WP_Error as array in ../woocommerce-shipping-australia-post/classes/class-wc-shipping-australia-post.php on line 1086

You can see this error message if your server can not use the wp_remote_get() function. This is something you can verify in the Status Report:

In this case, we recommend you to contact your hosting company so that they update your server.

Frequently Asked Questions

↑ Back to top

Does this support discounted/negotiated rates from Australia Post Business?

↑ Back to top

No. And there are no plans at this time to add it in the future.

How do I make it return Australia Post Letter Rates?

↑ Back to top

To get Australia Post to return letter rates, you will have to configure custom boxes in the extension using the Pack into boxes with weights and dimensions (Recommended) method.

Once you have chosen this method, please be sure to enter the box sizes you require (please ensure that these box sizes are same as the letter-box sizes mentioned in the Australia Post website – otherwise the extension will not calculate letter rates), and please select Envelope from the drop down list:

By doing this, the Australia Post extension will fetch letter rates using the API, and fetch accurate letter rates for your customers.

How do I make it return Australia Post Satchel Rates?

↑ Back to top

Satchel rates will be returned if the item (or the outer dimensions of your boxes, if you are using box packing) fit inside the satchel dimensions.

• 500g satchels are 335mm x 220mm ( W x H ) and are suitable for shipping CDs, iPods, mobile phones.
• 1kg satchels are 385 x 265mm ( W x H ).
• 3kg satchels are 405mm x 310mm ( W x H ) and are suitable for Fashion, books, digital cameras, toys.
• 5kg satchels are 510 x 435mm ( W x H ).

When a service is made up of several types of rate, including satchel, e.g. Regular Post, Satchel rates will only be used if they are the cheapest.

If you are using box packing, choose a box L x W x H outer size which would fit inside a satchel. The length you use is up to you – usually this will be determined by the products being shipped.
