Los Angeles and Sydney sit more than 12,000 kilometres apart across the Pacific. A container ship crosses that gap over a matter of weeks, while a cargo flight does it in a fraction of the time. That speed gap is the main reason so many shippers choose air freight from USA to Australia for urgent, high-value or time-sensitive goods.
Booking air freight is more than putting boxes on a plane. You need to understand chargeable weight, export and import paperwork, Australia's strict biosecurity rules and the trade agreement that may reduce the duty you pay. Whether you are a manufacturer in California sending parts to Melbourne or an e-commerce brand in New York shipping stock to Brisbane, this guide walks you through each stage of the journey.
International air freight usually costs considerably more per kilogram than sea freight. So why do US exporters and Australian importers use it? It comes down to speed, predictability and the type of goods you are moving. If you are still weighing up your options, our guide to air freight vs sea freight compares the two in more detail.
Air cargo is the practical choice when goods cannot wait. Think temperature-sensitive pharmaceuticals, seasonal fashion, product launches, or a replacement part for a broken machine on a Western Australian mine site. When downtime or a missed sales window costs money, the extra freight spend can pay for itself.
Airlines operate to fixed schedules, and air freight is generally less exposed to port congestion or blank sailings (cancelled voyages) than ocean shipping. Flights can still be affected by weather, capacity, security screening and connections, but most air shipments come with milestone tracking so you can see where your cargo is.
Because goods spend less time on the move, there is less exposure to moisture, temperature swings and repeated handling. Cargo insurance premiums depend on the goods, their value, packing, route and the insurer's terms, so ask your insurer how the transport mode affects your cover.
Not every airport handles international freight equally well. Most shipments between the two countries move through major gateway airports, and choosing the right gateway at each end can affect both cost and transit time.
Your shipment will usually be trucked from your supplier's warehouse to one of these hubs before it flies:
Every shipment follows a similar path. Here is what happens to your cargo from pickup to delivery.
Depending on your Incoterms, your forwarder's US partner collects the goods from the supplier (for example under EXW), or the supplier delivers them to the origin warehouse or airport (for example under FCA). The cargo is checked, weighed, measured and labelled. If you are unsure who is responsible for each leg, read our guide to Incoterms.
Before leaving the United States, export information is filed with US authorities where required, usually through the Automated Export System (AES). Cargo flying on passenger aircraft must also be security screened under US rules, so it needs to be ready and correctly documented before cut-off.
Your cargo travels either in the belly hold of a passenger aircraft or on a dedicated freighter. Freighters, often called CAO (Cargo Aircraft Only), can carry taller pieces and some dangerous goods that cannot go on passenger flights.
This is the most important stage. The Australian Border Force (ABF) and the Department of Agriculture, Fisheries and Forestry (DAFF) both assess incoming cargo. Accurate paperwork and correct tariff classification help avoid holds, inspections and extra costs. A licensed customs broker lodges your import declaration and manages any biosecurity requirements. Learn more about our customs and quarantine clearance service.
Once released, the goods are collected from the airline terminal and delivered to your warehouse, store or customer. This last leg is often called last-mile delivery.
Missing or inconsistent paperwork is one of the most common causes of clearance delays. Make sure your supplier and forwarder have:
Shipments valued above the low-value threshold set by the ABF need a full import declaration, which a customs broker can prepare and lodge for you.
You will rarely get a flat per-box price for air freight. Rates are worked out on chargeable weight and then adjusted for the route, service level and extra charges.
Airlines charge on whichever is greater: the actual weight or the volumetric weight of your shipment.
The standard air freight formula: Length (cm) × Width (cm) × Height (cm) ÷ 6000 = volumetric weight in kg.
Some express couriers use a divisor of 5000 instead, which produces a higher volumetric weight for the same box.
Worked example: A pallet measures 120 cm × 100 cm × 80 cm and weighs 95 kg. Its volumetric weight is 120 × 100 × 80 ÷ 6000 = 160 kg. Because 160 kg is greater than 95 kg, you are charged on 160 kg.
In short, a box of pillows (light but bulky) is charged on volume, while a box of steel parts (small but heavy) is charged on weight. For more examples, see our guide to CBM and volumetric weight calculations and our air freight cost calculator guide.
Shippers moving goods from the USA to Australia usually choose between three broad service levels:
| Service level | Speed | Relative cost | Best for |
|---|---|---|---|
| Express courier | Usually the fastest door-to-door option | Usually the highest per kilogram | Documents, samples and smaller parcels |
| Standard air freight | Fast, with scheduled airport-to-airport services | Generally lower per kilogram than express for larger shipments | Palletised commercial cargo |
| Deferred or economy air | Slower than standard air, as cargo flies when space is available | Generally lower than standard air | Heavier cargo that is not urgent |
Actual air freight rates and transit times depend on chargeable weight, origin and destination airports, airline capacity, fuel surcharges, security screening, the type of goods, pickup and delivery requirements, customs clearance and broader market conditions. Contact our team for a shipment-specific quotation and transit estimate.
Tip: The rate per kilogram usually falls as the shipment gets heavier, so a 500 kg shipment typically has a lower per-kilogram rate than a 50 kg shipment. Consolidating orders can make air freight more economical.

The Australia–United States Free Trade Agreement (AUSFTA) can make a real difference to your landed cost. Under AUSFTA, many goods that originate in the United States can enter Australia duty-free or at a preferential rate, as long as they meet the agreement's rules of origin.
A few points to keep in mind:
The ABF publishes the rules for each agreement on its Free Trade Agreements page. To see how duty is worked out, read our guide to understanding duty calculation.
Australia has a unique environment, and DAFF enforces strict biosecurity controls to protect it. Before you ship, check the import conditions for your goods in BICON, DAFF's Biosecurity Import Conditions system, and the guidance on DAFF's importing pages.
Goods that do not meet the rules may be held, treated, re-exported or destroyed at the importer's expense, and penalties can apply.
| Category | Status | What to know |
|---|---|---|
| Fresh food | Generally prohibited or strictly controlled | Fresh fruit, vegetables, meat and eggs face tight restrictions. Check BICON before shipping any food. |
| Timber and wood packaging | Restricted | Wooden pallets and crates should be ISPM 15 treated and marked, or otherwise meet DAFF requirements. |
| Soil and sand | Not permitted as contamination | Used tyres, machinery or camping gear carrying soil can be held for cleaning or treatment. |
| Seeds and plants | Restricted | Many require an import permit and testing. Check BICON for your specific product. |
| Weapons | Restricted | Includes items such as paintball markers, certain knives and firearm parts, which may need permission to import. |
| Electronics | Generally allowed | Lithium batteries must be correctly declared and packed as dangerous goods. |
Packing warning: Never use straw, rice hulls or other untreated organic material as packing filler. Use bubble wrap, foam or processed paper instead.
The right logistics partner matters as much as the flight. Many forwarders operate in the market, but experience on the trans-Pacific route makes a difference. When comparing providers, ask:
Omega Cargo provides air freight and customs clearance services for Australian importers, so your freight and paperwork can be managed together.
Air cargo is handled by forklifts, moved through terminals and loaded into aircraft units, so good packing protects your goods and avoids extra charges.
Air freight is much faster than sea freight, but the total door-to-door time is more than the flight itself. It depends on the service level, origin and destination airports, flight connections, airline capacity, security screening, customs and biosecurity clearance, and pickup and delivery arrangements. Contact our team for a transit estimate based on your shipment.
It depends on size and urgency. Express couriers often suit small parcels and documents. For larger palletised shipments, standard or deferred air freight booked through a freight forwarder is often more economical. For large shipments that are not urgent, sea freight usually has the lowest cost per unit.
Yes, the major express couriers deliver to Australia. For larger commercial shipments, especially pallets, a freight forwarder can often provide better value and handle customs clearance as part of the same service. Comparing quotes for your actual weights and dimensions is the best way to decide.
In most cases, yes. Under current ABF rules, GST on imported goods is 10% of the value of the taxable importation. That value is the customs value of the goods plus any duty payable, plus the cost of transporting and insuring the goods to Australia. Exemptions can apply, so confirm the current rules on the ABF's GST and other taxes page or with your customs broker.
Many US-origin goods can enter Australia duty-free or at a preferential rate under AUSFTA, provided they meet the rules of origin and you hold the right evidence. Goods made outside the USA may not qualify even if they ship from a US airport.
Yes, but lithium batteries are classified as dangerous goods. They must be packed, marked and documented according to IATA Dangerous Goods Regulations, and some configurations can only travel on cargo aircraft. Extra handling requirements and charges usually apply.
Chargeable weight is the greater of your shipment's actual weight and its volumetric weight. For standard air freight, volumetric weight is calculated as length × width × height in centimetres divided by 6000.
For commercial shipments that need a full import declaration, most importers use a licensed customs broker. A broker classifies your goods, applies any free trade agreement preference, calculates duty and GST, and manages biosecurity requirements.
Air freight from USA to Australia does not have to be complicated. With accurate paperwork, careful packing and a clear understanding of what drives your costs, you can bring goods in from the USA with confidence.
