In a world of instant expectations, same-day delivery and 3-hour delivery can do more than move parcels faster. They can help retailers convert urgent shoppers, compete with fast-moving marketplaces and turn speed into a standout customer experience.
Key points
- Same-day and 3-hour delivery can help retailers meet urgent customer needs, from last-minute gifts to essential health, beauty, baby and pet products.
- Australia Post’s same-day and 3-hour delivery capability is powered by Rendr, a last-mile orchestration platform that connects businesses to a large network of on-demand delivery providers.
- Chemist Warehouse has used Rendr to support decentralised fulfilment from its store network, helping simplify fast delivery operations and serve more customers through same-day and 3-hour delivery.
Customers increasingly expect delivery within hours
According to the Australia Post eCommerce Report 2026, 43% of consumers are willing to pay extra for same-day or next-day delivery - especially Gen Z (59%) and Millennials (59%).
For retailers, speed is no longer just a convenience play. It can be the difference between meeting customers in the moment and losing the sale.
This is particularly relevant for categories such as health, beauty, pharmacy, baby, pet, fashion and gifts, where speed can be closely tied to the customer’s reason for buying. When a purchase is urgent, convenience and confidence matter.
Turn delivery speed into a reason to buy now
Same-day and 3-hour delivery can also work as a powerful conversion lever for retailers looking to compete with global marketplaces.
Promoting speedy delivery across product pages, abandoned cart emails, paid media and seasonal campaigns can give customers a stronger reason to buy now, especially when timing matters. At checkout, a faster delivery option can help reduce hesitation, create urgency and ultimately, create a stronger customer delivery experience.
A simpler way to offer faster delivery
Australia Post’s same-day delivery capability is powered by Rendr, a last-mile orchestration platform that connects businesses with multiple same-day delivery carriers through a single touchpoint.
Rendr’s carrier network includes more than 60 on-demand delivery providers. The platform automatically selects the best delivery option for each order and supports fulfilment from stores or distribution centres, helping businesses expand fast delivery coverage without adding operational complexity.
For customers, this means flexible delivery windows, live tracking and a more consistent delivery experience. For businesses, it means greater visibility, simplified carrier management and the ability to use existing store or fulfilment networks in smarter ways.
Introducing 3-hour delivery
For customers who need their purchase almost immediately, Australia Post also offers 3-hour delivery, powered by Rendr.
Available through an existing Australia Post Direct API integration, the service enables eligible customers to select 3-hour delivery at checkout. Orders are fulfilled through Rendr’s integrated delivery network, with tracking updates available throughout the delivery journey.
This can help retailers meet demand for ultra-fast fulfilment while leveraging existing store networks and delivery infrastructure.
Proven at scale: Chemist Warehouse
Chemist Warehouse had been offering same-day delivery through multiple providers, but managing different delivery pathways added complexity for stores and franchisees.
By consolidating its fast delivery offering with Rendr, the retailer gave stores a single platform to manage fast delivery orders. The move also supported a broader shift away from a centralised fulfilment model, enabling online orders to be fulfilled directly from stores closer to customers.
Supported by Rendr, Chemist Warehouse created a decentralised fulfilment strategy with online orders sent directly from stores. The model helps spread fulfilment across the store network without requiring dedicated eCommerce roles in stores.
The results show the potential of fast delivery at scale. The retailer has enabled same-day and 3-hour delivery across a large store network, with on-demand delivery now supporting a significant share of online trade and average fast delivery times of approximately 56 minutes.
Which delivery speed should your business offer?
Different delivery speeds suit different customer needs. Use the table below to help decide which delivery speeds to offer – based on customer urgency, product type and your own fulfilment capability.
| Delivery speed | When to offer it | Who uses it |
|---|---|---|
Standard delivery | For planned purchases where cost matters more than speed - for example, a customer buying household supplies early in the week and not needing them immediately. | Best for price-sensitive shoppers, everyday items and non-urgent purchases. Helps businesses offer a lower-cost delivery option and manage fulfilment efficiently. |
| Express / next-day delivery | For customers who want faster delivery but don’t need it within hours. Examples are ordering clothing or gifts on a Thursday to receive in time for a weekend event. | Useful for time-sensitive purchases, replenishment items and customers who value certainty. Helps improve checkout confidence and reduce delivery-related friction. |
| Same-day delivery | For urgent purchases needed later that day - for example, a last-minute gift, clothing or tech item ordered in the morning for afternoon delivery. | Popular with shoppers who value convenience and immediacy. Helps retailers compete with faster delivery expectations and use stores or fulfilment centres as local delivery hubs. |
| 3-hour delivery | For high-urgency purchases needed almost immediately - for example, pharmacy, health, baby, pet or essential items needed within a few hours. Ideal to offer on Fridays. | Best for essentials, beauty and pharmacy products, gifts, replacement items and impulse purchases. Helps businesses meet ultra-fast fulfilment demand and create a premium delivery experience. |
