> How Australian online retailers can set a free shipping threshold that lifts basket size without eroding margin, using current shopper and carrier data.

A free shipping threshold works when it sits a little above your typical order value and the margin on the extra items covers the delivery cost you absorb. In Australia, the most common threshold among businesses that use one is $51 to $100, and free shipping remains shoppers' top delivery preference. The right number for your store comes from your own order data, your carrier rates and your product margins, then testing.

## Why free shipping still carries so much weight

Shipping cost is one of the most sensitive points in the buying decision. Australia Post's [eCommerce Report 2025](https://auspost.com.au/content/dam/ecommerce-report/australia-post-ecommerce-report-2025.pdf) found that 56% of Australians ranked free shipping as their top delivery priority in 2024, ahead of fast delivery and free returns. The same report lists unexpected costs at checkout as the number one friction point shoppers report when buying online.

That matches checkout research elsewhere. [Baymard Institute](https://baymard.com/blog/reduce-cart-abandonment) reports that 39% of shoppers abandon a checkout because of additional fees such as delivery charges and taxes. In Australia, ShipStation research reported by [Power Retail](https://powerretail.com.au/shoppers-favouring-cheaper-delivery-over-speed/) found 63% of shoppers would abandon a purchase if shipping fees were too high.

## How Australian businesses use free shipping today

According to the 2025 Australia Post report, 35% of surveyed businesses always offer free shipping, 30% offer it once a spending threshold is met, and the most common threshold is $51 to $100. For 93% of businesses with a threshold, the free option ships at standard speed rather than express.

Basket sizes are under pressure, which makes thresholds more useful as a nudge. Australia Post's [quarterly update](https://auspost.com.au/business/grow-your-business/trends-insights) puts the average online basket at about $90, with growth coming from more purchases rather than bigger baskets. Its [2026 report](https://auspost.com.au/content/dam/auspost_corp/media/documents/ecommerce-reports/annual-ecommerce-reports/ecommerce-report-2026.pdf) suggests rewarding bigger spends and using delivery incentives to help shoppers complete the order.

## How to calculate your threshold

Start with numbers you already have:

1. **Average order value (AOV).** Pull the last 6 to 12 months of orders and look at the median as well as the mean, because a few large orders can skew the average.
2. **Order value distribution.** Find where most orders cluster. A threshold set 15 to 30% above the cluster gives many shoppers a realistic reason to add one more item.
3. **Real delivery cost per order.** Use your actual carrier invoices, including fuel levies and surcharges. Remember that carriers charge on the greater of dead weight and cubic weight. Australia Post explains that it uses a [cubic conversion factor of 250kg per cubic metre](https://auspost.com.au/business/grow-your-business/business-ideas-blog/what-is-cubic-weight), so a light but bulky parcel can cost more than its weight suggests.
4. **Gross margin on add-on items.** The extra spend needed to reach the threshold must earn enough margin to cover the shipping you absorb.

A simple check: if your typical delivery costs $12 and your gross margin is 40%, a shopper needs to add about $30 of product to pay for the shipping. If the gap between AOV and your threshold is much larger than that, many shoppers will not bother. If it is much smaller, you may be giving away delivery that customers would have paid for.

## Design choices that make thresholds work

- **Show progress.** A cart message such as "You're $14 away from free shipping" makes the goal concrete.
- **Offer sensible add-ons.** Suggest low-cost, high-margin complements near the threshold amount, not random products.
- **Split by region or carrier zone if needed.** Australia Post's 2025 report suggests tailoring offers by region, such as free shipping for certain states or metro areas, where costs differ sharply.
- **Keep express separate.** Free standard delivery with paid express protects margin. The 2026 Australia Post report suggests trialling a free next-day threshold and monitoring conversion against margin impact.
- **Treat marketplace orders differently.** Marketplaces set their own shipping display rules, so check each channel's settings rather than copying your webstore threshold.

## Test, then review quarterly

A threshold is not a set-and-forget number. Carrier prices change. Australia Post lists price changes for eParcel and StarTrack services effective [1 July 2026](https://auspost.com.au/business/shipping/postage-costs/business-pricing-updates), and your product mix shifts over time. Run a controlled test where possible, comparing conversion rate, AOV and contribution margin per order, then recheck the numbers each quarter and before peak season.

Older shoppers may need a different approach. Australia Post found Baby Boomers and Builders want free shipping without a spending threshold during sale events, so a time-limited threshold-free promotion can suit some customer bases.

## How eComChannels helps

A threshold is only as good as your cost data. [AI auto shipping](https://ecomchannels.com/products/ai-shipping/) records the carrier, service, weight and cost of every consignment across Australia Post, StarTrack, CouriersPlease and Allied Express, so you can see what delivery really costs per order, by region and by product, rather than relying on estimates. It also produces labels and manifests automatically, which keeps the handling cost of each order down. [Order management](https://ecomchannels.com/products/order-management/) holds order values from every channel in one place, which makes AOV and order distribution easy to analyse, and our [branded storefronts](https://ecomchannels.com/products/storefronts/) let you display delivery costs and threshold messages clearly on your own site. Together they help you set a threshold that lifts basket size while protecting margin.

## FAQ

### What is a good free shipping threshold in Australia?

Among Australian businesses that use one, the most common threshold is $51 to $100, according to Australia Post. Your own threshold should sit modestly above your typical order value and be covered by the margin on the extra items shoppers add.

### Should I offer free shipping on every order instead?

Only if delivery costs are small relative to your margins or built into your prices. Australia Post found 35% of businesses always offer free shipping, but for bulky or low-margin products a threshold or flat rate is usually more sustainable.

### Does a free shipping threshold apply to marketplace orders?

Not automatically. Marketplaces such as Amazon and eBay have their own shipping settings and display rules, so configure shipping per channel and check the margin impact separately.
