One of the most common questions Shopify merchants face from customers is: “When will my order arrive?” The honest answer depends on several factors: the Australia Post service you selected, where the parcel is being sent from and to, whether both postcodes fall within the Express Post next business day network, and whether the parcel was lodged before the lodgement cut-off. This guide walks through the official Australia Post delivery time estimates for domestic routes including Melbourne to Sydney, Sydney to Brisbane, Adelaide to Perth, same-state deliveries, and regional orders.

The Two Domestic Services That Determine Australia Post Delivery Time
Every Shopify merchant shipping domestically with Australia Post is choosing between two core services, and that choice is the primary variable in Australia Post delivery time:
Parcel Post
- Same state: 2 – 4 business days
- Interstate: 3 – 6 business days
- Coverage: Australia-wide
Express Post
- Same state: 1 – 2+ business days
- Interstate: 1 – 3+ business days
- Coverage: Australia-wide
All delivery times are based on the number of business days items take to arrive following the day of posting. This means a parcel lodged on Monday is counted from Tuesday. A parcel lodged on Friday with a 3-business-day estimate arrives on Wednesday the following week, not over the weekend.
For Shopify merchants deciding between the two services based on cost, the guide on Australia Post shipping cost optimization for Shopify covers how to match service selection to order type and margin.
Australia Post Delivery Time by Route: Key Interstate Comparisons
Using Australia Post’s official delivery speed guidance, here is how the two services map across the most common interstate Shopify shipping routes:
| Route | Parcel Post | Express Post |
|---|---|---|
| Melbourne → Sydney | 3 – 6 business days | 1 business day (NBD network)* |
| Sydney → Brisbane | 3 – 6 business days | 1 business day (NBD network)* |
| Melbourne → Brisbane | 3 – 6 business days | 1 – 3+ business days |
| Sydney → Adelaide | 3 – 6 business days | 1 – 3+ business days |
| Melbourne → Adelaide | 3 – 6 business days | 1 – 3+ business days |
| Sydney → Perth | 3 – 6 business days | 1 – 3+ business days |
| Melbourne → Perth | 3 – 6 business days | 1 – 3+ business days |
| Any capital → Darwin | 3 – 6 business days | 1 – 3+ business days (no NBD guarantee) |
Note: Next business day delivery only applies where both origin and destination postcodes fall within the Express Post next business day network. Darwin is excluded from the national next business day delivery network.
Express Post Next Business Day Network: Which Cities and Postcodes Qualify
The Australia Post delivery time of next business day via Express Post is not available everywhere; it applies only within the Express Post next business day delivery network. The eligible postcode ranges by city are:
| City/State | Eligible Postcodes |
|---|---|
| Sydney | 1000 – 1920, 2000 – 2234, 2555 – 2574, 2740 – 2786 |
| Melbourne | 3000 – 3207, 3340 – 3341, 3750, 3755 – 3757, 8001 – 8785 |
| Brisbane | 4000 – 4209, 9016 – 9464 |
| Gold Coast | 2484 – 2490, 4210 – 4275, 9726 |
| Adelaide | 5000 – 5174, 5800 – 5950 |
| Canberra | 0200, 2600 – 2620, 2900 – 2914 |
| Perth CBD | 6000 – 6005, 6800 – 6892 |
| Tasmania | 7000 – 7019, 7050 – 7053, 7055, 7248 – 7250, 7258, 7275 – 7300, 7315, 7320 |
If the destination postcode falls outside these ranges, for example, a customer in the Central Coast of NSW, regional Queensland, or outer suburban Perth, Express Post still offers the fastest available service, but the next business day guarantee does not apply, and the Australia Post delivery time extends to 1 – 3+ business days interstate.
Understanding the full postcode coverage is equally important for return shipments. For guidance on return label setup and how it connects to delivery timelines, see Australia Post return labels for Shopify orders.
Same-State Australia Post Delivery Time: What to Expect Within VIC, NSW, QLD, and More
Same-state deliveries are generally faster than interstate ones, but the delivery time still varies between metro and regional destinations within the same state.
For Parcel Post:
- Same state: 2 – 4 business days
For Express Post:
- Same state: 1 – 2+ business days
The “2+ business days” Express Post estimate for same-state deliveries reflects routes where both postcodes are within the same state, but one or both addresses are outside the capital city metro network. A Sydney-to-Sydney delivery within eligible postcodes can be next business day. A Sydney-to-Tamworth delivery, both within NSW, will take longer because Tamworth falls outside the Express Post next business day network.
Key practical implications for Shopify merchants:
- A Melbourne-based merchant shipping to customers in Melbourne’s outer suburbs (outside the eligible postcode list) should not communicate next-day delivery.
- A Sydney-based merchant shipping to regional NSW can offer Express Post at checkout as the faster service, but should set the delivery expectation at 2 – 4 business days rather than 1.
- For same-state rural and remote destinations, Australia Post notes that longer delivery times may apply to Australian external territories and Defence Force post offices.
Knowing which of your customers fall inside and outside the Express Post network helps you set accurate delivery promises at checkout, which directly reduces WISMO enquiries after dispatch.

What Affects Australia Post Delivery Time Beyond the Service Selected
Service selection and postcode eligibility set the baseline Australia Post delivery time, but several additional factors can extend it:
- Lodgement cut-off time: Items should generally be lodged in yellow street posting boxes before 4 pm Monday to Friday. However, other times may apply in many areas. A parcel lodged after the cut-off is treated as lodged on the following business day.
- Public holidays: The next guaranteed day of delivery for Express Post items posted before closing time on the business day before a public holiday will be the next business day after a public holiday.
- Network congestion during peak periods: During peak eCommerce periods pre-Christmas, post-Christmas sales, and major retail events, network congestion can extend Australia Post delivery time beyond standard estimates, even for Express Post shipments.
- Label accuracy: A mislabelled parcel that requires manual intervention at processing adds delay. Inaccurate dimensions, wrong packaging type declarations, or address errors can all slow a parcel through the network.
- Missed first delivery attempt: If a customer isn’t home and there’s no safe place to leave the parcel, the delivery timeline extends by however long the customer takes to collect from the Post Office or arrange redelivery up to 10 business days before the parcel is returned to sender.
How the PluginHive Australia Post Ship App Surfaces Delivery Times at the Shopify Checkout
Knowing the correct Australia Post delivery time for each route is only half the challenge. The other half is getting that information in front of your customer at the moment they’re choosing a shipping option. The PluginHive Australia Post Ship app connects your Australia Post account directly to Shopify and displays real-time, postcode-aware service options and delivery estimates at checkout.
Here’s how the app addresses delivery time accuracy specifically:
- Live, postcode-matched service display. The app applies origin and destination postcode logic when displaying Australia Post services at checkout. Customers whose postcodes fall within the Express Post next business day network see next-day delivery as an option.
- Account-linked rates alongside delivery times. The app fetches rates from your connected MyPost Business or eParcel Contract account and displays them alongside the delivery estimate.
- Tracking sync for delivery visibility post-dispatch. The tracking number is automatically pushed to the Shopify order once the label is generated, and the customer receives a fulfilment notification. For more on how this tracking sequence works, see the guide on Australia Post delivery tracking for Shopify.
- Bulk label processing for peak periods. During high-volume dispatch days, the app supports batch label generation from the Shopify order list, reducing per-order handling time and ensuring parcels are lodged on time to meet the Australia Post delivery time the customer was shown at checkout.
Conclusion
Australia Post delivery time depends on a combination of service choice, postcode eligibility, lodgement timing, public holidays, and network conditions at the time of sending. For the most commonly shipped interstate routes, Melbourne to Sydney and Sydney to Brisbane, Express Post offers next business day delivery within eligible metro postcodes. For routes to Perth, Darwin, or regional addresses, both services take longer, and the next-day guarantee doesn’t apply.
Setting accurate delivery expectations at the Shopify checkout, matched to the actual postcode pair, service selected, and current lodgement timing, is what prevents the mismatch between customer expectation and actual arrival date that generates the most support enquiries. The PluginHive Australia Post Ship app handles this automatically, surfacing postcode-aware, account-linked service options and delivery time estimates directly at your Shopify checkout.
FAQs
Q: What is the Australia Post delivery time from Melbourne to Sydney?
Via Express Post, next business day is provided if both origin and destination postcodes are within the eligible network, and the parcel is lodged before the 4 pm cut-off. Via Parcel Post, 3 – 6 business days. All delivery times are counted from the business day after lodgement.
Q: Does Australia Post offer next business day delivery to Perth from Sydney or Melbourne?
Partially. Perth CBD (postcodes 6000 – 6005 and 6800 – 6892) qualifies as a destination within the Express Post next business day network, but Perth CBD is not eligible as a lodgement origin. Darwin has no next business day coverage at all.
Q: How long does Parcel Post take within the same state?
Australia Post estimates 2 – 4 business days for same-state Parcel Post deliveries. For same-state Express Post, the estimate is 1 – 2+ business days, with next business day applying only within the eligible metro postcode network.
