Every year I hear from businesses that did everything right for eleven months and then lost customers in December. Peak season exposes every weakness in a supply chain. Carriers run at capacity, cut-offs move earlier, surcharges appear, and freight that would normally fly overnight waits a day or two. The businesses that get through peak without drama are not lucky. They plan earlier, forecast honestly and have a fallback ready.
This guide covers Australia's peak periods and how to plan domestic air freight around them. It is part of our guide to optimising your business supply chain with domestic air freight.
Australia's peak freight calendar
| Period | What drives demand | Who is most affected |
|---|---|---|
| February | Valentine's Day | Florists, chocolate and gift retailers |
| March to April | Easter and its public holidays | Food, retail, anyone with time-critical freight around the long weekend |
| May | Mother's Day | Flowers, gifting and ecommerce |
| June | End of financial year (EOFY) sales and business purchasing | Retail, technology, office and trade supplies |
| Late October to November | Click Frenzy, Singles Day, Black Friday, Cyber Monday | Ecommerce and parcel networks |
| December | Christmas gifting and business shutdowns | Almost everyone |
| Late December to mid-January | Reduced services over public holidays, Boxing Day sales, returns | Businesses that stay open over the break |
Weather adds to the pressure. The northern storm and cyclone season and the southern bushfire season both overlap the Christmas peak, so disruptions often arrive when networks have the least spare capacity.
What changes for air freight during peak
- Capacity tightens. Freighters fly full, and passenger aircraft holds fill with holiday travellers' baggage, leaving less room for cargo.
- Cut-offs move earlier. Carriers bring forward lodgement and pick-up times to process higher volumes.
- Transit times stretch. Standard services may roll freight to the next available flight, and priority products fill first.
- Surcharges can appear. Some carriers apply peak surcharges or suspend discounts for certain services.
- Allocations matter. Customers with committed volumes and good forecasting are usually looked after first.
The 2026 Sydney change you need to plan for
This year brings a significant change to Sydney's air freight network just before the Christmas peak. Western Sydney International (Nancy-Bird Walton) Airport opened for freight on 26 July 2026, with Qantas Freight starting regular services the following evening. The airport operates without a curfew.
Under the Sydney Airport Curfew Act 1995, 1 November 2026 has been set as the intended date for Western Sydney International to open for night aircraft movements. From then, the freight flights currently permitted during Sydney Kingsford Smith Airport's overnight curfew will no longer be allowed, except in emergencies or with special dispensation. Operators will need to move those services to Western Sydney or reschedule them.
For shippers, this could mean changes to pick-up times, lodgement locations and cut-offs for overnight services in and out of Sydney, right at the start of peak. Ask your carriers now:
- Which of your overnight services will operate from Western Sydney after 1 November?
- Will pick-up or lodgement cut-offs change for my Sydney sites?
- Will transit times to or from any lanes change?
- Are any new charges linked to the move?

A peak season planning timeline
August to September: forecast
- Review last year's peak volumes by lane, week and service level.
- Build a forecast that includes planned promotions and new products.
- Identify the products and lanes where speed matters most.
September to October: agree capacity
- Share forecasts with your carriers and ask what they can commit.
- Confirm peak cut-offs, surcharges and public holiday schedules in writing.
- Set up and test a backup carrier or road service on key lanes.
- Order packaging and consumables early, because suppliers run short too.
October: position stock
- Move bulky and slow-moving stock by road to where it will be needed, well before peak.
- Keep air freight for fast-moving and high-value lines. Our article on using domestic air freight to reduce inventory costs explains how to decide which lines need a buffer and which can rely on fast replenishment.
November to December: operate and communicate
- Publish Christmas delivery cut-offs by zone and service on your website.
- Monitor on-time performance daily and move freight to backup options quickly if a lane slips.
- Keep customers informed about delays before they have to ask.
January: review
- Compare actual volumes and performance with your forecast.
- Record what worked and what failed while it is fresh.
Setting realistic Christmas cut-offs
Christmas cut-offs are among the most important messages an online retailer publishes all year. Base yours on your carriers' published peak cut-offs, then add your own picking and packing time and a buffer. Set different dates for metro, regional and remote zones, and for express and standard services. Remember that Western Australia and the Northern Territory need earlier cut-offs than the east coast if orders ship from Sydney or Melbourne. Our guide to domestic air freight for ecommerce covers delivery promises in more detail.
Publish cut-offs in early November. If your carriers bring them forward, update the dates promptly and say why. Customers respond far better to an early warning than a missed delivery.
Contingency plans that work
- Dual carriers. Keep a second provider active on your most important lanes, with accounts, labels and integrations ready to use.
- Road fallback. For shorter lanes, road express may be almost as fast when air capacity is tight.
- Priority for what matters. Reserve priority air products for orders where delay costs the most, such as business-critical parts, perishables and customer express orders.
- Split shipments. Send part of a large order by air to meet the deadline and the rest by road.
- Weather plans. Know which sites and lanes are exposed to cyclones, floods and bushfires, and what you will do if they close.
Peak season rewards the businesses that plan in September, not the ones that start calling carriers in December.
EOFY and the rest of the year
Smaller peaks deserve the same approach on a smaller scale. EOFY brings a surge in business purchasing and retail sales in June, so confirm capacity in May. Florists and gifting businesses should treat Valentine's Day and Mother's Day as their own Christmas, with perishables booked on direct flights well ahead. Check state public holidays too, such as Melbourne Cup Day in Victoria and the different King's Birthday dates between states, which can shift delivery schedules.
Planning for peaks is an essential part of a reliable air freight strategy. For the complete framework, read our guide to using domestic air freight to optimise your supply chain.
Frequently asked questions
When is peak season for domestic air freight in Australia?
The main peak runs from late October to Christmas, driven by online sales events and Christmas gifting. Smaller peaks occur around EOFY in June, Easter, Valentine's Day and Mother's Day.
How early should I plan for Christmas freight?
Start forecasting in August or September, agree capacity and cut-offs with carriers by October, and publish customer delivery cut-offs in early November.
What is changing at Sydney airports in 2026?
Western Sydney International Airport opened for freight in July 2026 without a curfew. From 1 November 2026, freight flights currently allowed during Sydney Kingsford Smith Airport's overnight curfew are intended to end, with overnight freight moving to Western Sydney. Check with your carrier how this affects your cut-offs and transit times.
Do carriers charge peak surcharges in Australia?
Some do, particularly on parcel and express services during the Christmas period. Ask your carrier for its peak-season charges and dates in writing before you finalise pricing to customers.
