Customers notice packaging waste more than most store owners realise; an oversized box, excessive plastic, or non-recyclable filler can undo the goodwill built by a great product. For WooCommerce stores shipping through Australia Post MyPost Business, sustainable packaging isn’t just good practice; it also lines up with where Australia Post itself is heading.
This guide covers practical sustainable packaging choices for WooCommerce sellers, where Australia Post’s own sustainability commitments fit in, and how to configure packaging correctly in WooCommerce so it doesn’t cost you accuracy on shipping rates.

Where Australia Post Stands on Sustainable Packaging
Australia Post continues to make progress toward its 2025 sustainability targets, including reducing carbon emissions, increasing renewable electricity use, and developing a more sustainable packaging range aligned with the National Packaging Targets. Its most popular branded satchels now contain at least 80% recycled content, while around 80% of its Australia Post and StarTrack branded packaging range contains more than 50% recycled content. Australia Post is also continuing to improve packaging outcomes across its network, with further progress supported by improvements in recycling infrastructure and the availability of alternative materials.
What this means practically for WooCommerce sellers: Australia Post’s own satchels and packaging products are moving in a more sustainable direction, but the packaging you use to prepare your product before handing it to Australia Post is entirely your own decision, and where most of the improvement opportunity actually sits.
Sustainable Packaging Materials for WooCommerce Orders
- Recycled and Recyclable Cardboard: Corrugated cardboard made from recycled content is widely available at a similar cost to standard boxes and is accepted in most kerbside recycling. It remains the most practical default packaging material for most WooCommerce product types shipped via Australia Post.
- Paper-Based Void Fill: Crumpled or shredded kraft paper is a recyclable, sustainable alternative to plastic bubble wrap or foam peanuts for filling space inside a box. For products that need genuine cushioning rather than just void fill, a layer of paper padding combined with tighter box sizing often reduces the need for plastic altogether.
- Compostable and Recycled-Content Mailers: For soft goods that don’t need rigid protection, clothing, textiles, accessories, compostable poly mailers or mailers made with recycled plastic content are a more sustainable alternative to standard plastic satchels. It’s worth checking the specific certification on any mailer marketed as compostable; some require industrial composting facilities and won’t break down in a home compost bin or standard kerbside collection.
- Paper Tape Instead of Plastic Tape: Paper packing tape seals just as effectively as plastic tape but is fully recyclable along with the cardboard box it’s sealing. Plastic tape often has to be removed before a box can go into standard cardboard recycling.
Right-Sizing Packaging For Australia Post MyPost Business Orders
The single most effective sustainable packaging decision a WooCommerce store can make isn’t about material choice at all; it’s box size. A box that’s larger than it needs to be wastes packaging material, requires more void fill to stop the product moving in transit, and increases the parcel’s cubic weight.
Australia Post charges parcels over 5kg based on actual weight or cubic weight, calculated as length x width x height (in cm) divided by 4,000; whichever is greater. An oversized box doesn’t just waste cardboard and filler; it can genuinely increase what you pay for shipping. Reviewing your box sizes against your actual product range and switching to a tighter fit reduces both material waste and cubic weight in the same move.
Setting Up Australia Post MyPost Business Packaging in WooCommerce
Sustainable packaging choices only translate into accurate shipping rates if your WooCommerce store’s packaging settings reflect what you actually use. The PH Australia Post MyPost Business Shipping for WooCommerce plugin lets you configure this directly.
To configure the plugin for your store, check out this guide: Setting Up WooCommerce Australia Post MyPost Business Plugin.
Choose How Products Should Be Packed
The plugin offers three packaging options: Individual Packing, Weight-Based Packing, and Box Packing. For sustainable packaging, Box Packing is ideal when you use Australia Post MyPost Business boxes, as you can define the box sizes you use and pack orders efficiently to reduce wasted space, excess packaging, and overcharging.
Select the Right Boxes for Your Products
Add the Australia Post MyPost Business box sizes you use. You can add multiple box sizes to give the plugin different packaging options. The plugin then automatically identifies the box that best fits the products, helping minimize unused space and unnecessary packaging.
Get Accurate Australia Post Rates
The plugin uses the selected packaging to calculate the Australia Post MyPost Business shipping rate. This helps ensure the rate shown at checkout reflects the actual package being shipped, rather than an oversized box that could lead to higher shipping costs.
Real-World WooCommerce Use Case
A WooCommerce store selling skincare and bath products was using a single, oversized satchel size for every order regardless of what was purchased, a single bar of soap shipped in the same packaging as a five-item bundle. Customers occasionally commented on the excess packaging in reviews, and the store’s cubic weight on smaller orders was inflating shipping costs unnecessarily.
How the Store Fixed It
The store introduced three box sizes matched to typical order profiles: small, medium, and bundle, using recycled cardboard and paper void fill instead of their previous plastic-lined satchels. They updated the corresponding box dimensions in the PH Australia Post MyPost Business Shipping for WooCommerce plugin’s Packaging settings and re-tested checkout rates across a sample of order types.
The Result
- Cubic weight on single-item orders dropped once the smallest box size was matched correctly, lowering shipping cost on the store’s most common order type.
- Customer comments about excess packaging stopped appearing in reviews.
- Checkout rates stayed accurate because packaging settings in the plugin were updated alongside the physical packaging change.
- Packaging material spend decreased slightly due to less void fill being needed with tighter-fitting boxes.
Conclusion
Sustainable packaging and accurate shipping rates aren’t competing priorities; right-sizing your boxes and switching to recyclable or recycled-content materials tends to reduce both waste and cubic weight at the same time. The part that’s easy to miss is keeping your WooCommerce packaging settings in sync with what you’re actually shipping in, since Australia Post’s rates depend on that data being correct.

FAQs
Q. Does Australia Post offer its own sustainable packaging products?
Yes. Australia Post sells parcel boxes, satchels, and envelopes as part of its retail packaging range, and its plastic postal satchels now contain an average of 50% recycled content.
Q. Do I need to update my WooCommerce settings every time I change packaging?
Yes, if the change affects box dimensions or packed weight. The PH Australia Post MyPost Business Shipping for WooCommerce calculates live rates based on the packaging settings configured in the plugin, so outdated box dimensions after a packaging change will produce inaccurate rates at checkout.
Q. Can I use different box sizes for different products?
Yes. You can define multiple box sizes in the packaging configuration and let the plugin determine the most suitable packaging for each order. This helps reduce unused space and unnecessary packaging material.
Q. Does sustainable packaging affect WooCommerce shipping rates?
It can. Smaller, lighter packaging can reduce the package dimensions and weight used for rate calculations, which may help avoid unnecessary shipping costs while reducing packaging waste.
Q. Can I use Australia Post MyPost Business with other shipping carriers?
Yes. If your store uses multiple carriers, the WooCommerce Shipping Services can help you offer Australia Post alongside other carriers and compare available shipping options at checkout.
