By For more than a century, Sydney's air cargo has flowed through a single airport at Mascot. That changed in 2026. Western Sydney International (Nancy-Bird Walton) Airport, known by its code WSI, opened for freight in late July, three months ahead of its first passenger flights. For the first time, businesses in New South Wales can choose between two airports when moving goods by air.
This guide compares Sydney Kingsford Smith Airport (SYD) and Western Sydney International (WSI) from a cargo point of view. It looks at operating hours, capacity, location, airline networks and what the next few years are likely to bring. For a broader overview of flying freight in and out of the city, see our Air Freight Sydney guide.
WSI at a glance: the key dates
The Australian Government confirmed the opening timeline in June 2026. Freight operations began on 26 July 2026, and Qantas Freight started regular flights the following evening. Passenger services are scheduled to begin on 25 October 2026, with Jetstar operating the first flight to the Gold Coast. Air New Zealand and Singapore Airlines have announced international services, with Singapore Airlines planning a daily flight to Changi from late November.
WSI is located at Badgerys Creek in Western Sydney. It has been built as a full-service airport that operates without a curfew, handling international, domestic and freight flights. At opening, the passenger terminal is designed for up to 10 million passengers a year, with room to expand as demand grows.
Operating hours: the curfew question
The single biggest difference for freight is time. Sydney Airport operates under the Sydney Airport Curfew Act 1995, which restricts most aircraft movements between 11 pm and 6 am. A limited number of freight flights using approved aircraft have been allowed during this period, but overall night-time capacity has been tight.
WSI has no curfew. Freight flights can take off and land at any hour. Under the Curfew Act, 1 November 2026 has been set as the intended date for WSI to be gazetted for night aircraft movements. From that point, the freight flights currently allowed at Kingsford Smith during curfew are expected to stop, apart from emergencies and special dispensations. In practice, overnight freighter activity in Sydney is set to move west.
This matters most for time-sensitive domestic freight. Parcels, e-commerce orders and urgent parts that need to leave Sydney late in the evening and arrive in Melbourne, Brisbane or Perth by morning depend on night flights. Our guide to overnight domestic air freight from Sydney explores this in more detail.
Capacity and airline networks
Sydney Airport remains Australia's largest international gateway. Much of its cargo travels in the bellies of passenger aircraft, and the sheer number of daily international flights gives shippers a wide choice of airlines and destinations. Dedicated freighters also operate from SYD, connecting Sydney with hubs across Asia, North America and the Pacific.
WSI's cargo network is starting from a smaller base. The first operators focus on domestic freighter services, led by Qantas Freight. As international passenger flights begin, belly capacity will grow, and the airport expects more freighter operators to join over time. For now, most international cargo, especially on less common routes, will continue to move through Kingsford Smith.
| Factor | Sydney Airport (SYD) | Western Sydney International (WSI) |
|---|---|---|
| Location | Mascot, about 8 km from the CBD | Badgerys Creek, Western Sydney |
| Operating hours | Curfew from 11 pm to 6 am | 24 hours, no curfew |
| Cargo operations | Long established, domestic and international | Freight from July 2026, passengers from October 2026 |
| International network | Extensive, with many airlines and destinations | Growing, starting with a small number of carriers |
| Main strength for freight | Choice of routes and belly capacity | Night flights and modern, purpose-built facilities |
| Nearby logistics hubs | Port Botany, Botany and inner south industrial areas | Eastern Creek, Erskine Park, Kemps Creek and the M7 corridor |
Location and road access
Location affects cost and transit time as much as flight schedules do. Kingsford Smith sits close to Port Botany and the inner-city industrial areas, which suits importers and exporters based in the eastern and southern suburbs. However, traffic around Mascot can be heavy, and trucking time can blow out during peak hours.
WSI sits in the heart of Western Sydney's growing warehouse and distribution belt. Many of the city's largest distribution centres are already located along the M4 and M7 corridors. The new M12 Motorway, which opened in 2026, links the airport directly to the M7. For businesses based in the west, WSI can mean shorter truck runs and more predictable collection times.
Planned upgrades, including a Metro rail connection and improvements to surrounding roads, should further strengthen the airport's links over the coming years.
Facilities and handling
WSI's cargo precinct has been designed from scratch, with modern layouts, space for automation and room to expand. New facilities can make handling faster and reduce the risk of congestion. Kingsford Smith's terminals have grown over decades and operate in a tighter footprint, but they benefit from experienced teams, established processes and close relationships with forwarders and customs brokers.
Storage schedules, free time and handling fees vary by terminal operator at both airports. If your cargo is routed through WSI for the first time, check the local charges separately. Our guide to storage fees at Sydney air cargo terminals explains what to look for.
Customs and biosecurity
Both airports operate under the same national rules for customs and biosecurity. Imports must be reported and cleared through the Australian Border Force's Integrated Cargo System, and biosecurity checks apply regardless of which airport the cargo arrives at. What may differ in the early months at WSI is the scale of local inspection and treatment services, so allow extra time for any cargo likely to need physical examination.
Which airport should you use?
For most shippers, the answer will depend on the shipment rather than a fixed preference. As a general guide:
- Choose SYD for international cargo that needs a wide choice of airlines and destinations, for belly cargo on passenger flights and for businesses based in the east and south of Sydney.
- Choose WSI for late-evening domestic freight, time-critical overnight deliveries and businesses based in Western Sydney or along the M7 and M4 corridors.
- Use both if your freight mix includes overnight domestic parcels and international shipments to a broad range of markets.
In many cases, your forwarder will choose the airport based on the airline booked. Ask them which gateway they plan to use and why, especially if pick-up or delivery location is important to you.
What the future holds
Over the next few years, WSI is expected to grow its international network as more airlines launch passenger flights and freighter operators take advantage of round-the-clock access. The airport's master plan allows for significant expansion, including additional cargo facilities.
Kingsford Smith will remain central to Sydney's air cargo market for the foreseeable future, particularly for international belly freight. The two airports are likely to complement rather than replace each other, with overnight freight concentrated in the west and a broad international network continuing at Mascot.
For shippers, more capacity should mean more options, particularly during busy periods. Our guide to navigating peak season in Sydney looks at how the new capacity may help before Christmas.
What shippers should do now
- Ask your forwarder about their WSI plans. Find out whether they have facilities, staff or transport partners near the new airport.
- Review your overnight domestic freight. If you rely on late-evening departures, check how cut-off times change once night flights are centred on WSI.
- Update delivery addresses and instructions. Make sure your warehouse and transport partners know which terminal to collect from.
- Watch for new international services. As more airlines start flying from WSI, new direct routes may open up for your markets.
- Build in extra time at first. New facilities often take a few months to settle, so allow a small buffer for early shipments.
Frequently asked questions
Is WSI connected by public transport?
A Metro rail line to the airport is planned, and interim bus services are being provided for passengers. For freight, road access through the M12 and M7 motorways is the main link.
Can I send international cargo through WSI now?
International cargo capacity at WSI will grow once international passenger flights start and more freighter operators arrive. Ask your forwarder which airlines are currently accepting international cargo at WSI for your destination.
Will freight rates be different at WSI?
Rates depend on the airline, route and demand rather than the airport alone. Local handling and trucking costs may differ, so compare full door-to-door quotes.
For most businesses, the practical impact will show up in small ways at first: a later cut-off time, a shorter truck run or a new direct route. Over time, those small gains add up.
A two-airport city
Sydney's move to two airports is one of the biggest changes to Australian air cargo in decades. Kingsford Smith offers reach and choice, while Western Sydney International offers time, space and a location close to the city's growing distribution hubs. Understanding both will help you plan faster, more reliable shipments. For more on airports, carriers and costs, visit our main Air Freight Sydney guide.
