International flights from Sydney Airport’s domestic terminals
The T2 and T3 domestic terminals will be upgraded for international flights.
By David Flynn, November 17 2025
International flights will depart from Sydney Airport’s domestic T2 and T3 terminals, which will be combined into a new hub to support future growth in passenger numbers.
This means that many travellers arriving on domestic flights by Qantas, Virgin Australia and regional airlines such as Rex will no longer need to transfer to the international T1 terminal to catch their overseas flight.
Instead, selected overseas flights by the likes of Qantas and Virgin would be likely to depart from the integrated T2/T3 hub, using “12 new swing gates” which can switch between domestic and international operations while keeping passengers separated.
“Bringing international services to the current domestic precinct will increase the efficiency of the airport and ensure Sydney Airport reaches its Master Plan forecast of 72 million passengers annually by 2045,” notes Sydney Airport.
Swing gates at T2-T3 will separate domestic and international passengers.
Possible Qantas and Virgin international flights departing from T2/T3 would include short hops to New Zealand, Bali and the Pacific Islands, which tend to use the same aircraft as the domestic network.
This would also simplify lounge access, with eligible passengers visiting the domestic lounge before making their way onto an overseas flight.
Sydney Airport says no decisions have yet been made on which airlines will move to the T2-T3 precinct, with “conversations currently underway with all airlines to understand their needs and preferences”.
The integration of T2 and T3 would add international flights to the departure boards.
Sydney Airport is now “calling for tenders for an architectural design and engineering firm to support the development of the landmark terminal upgrade project, which will link the T2 and T3 domestic terminals to create a seamless passenger experience.”
The ’rotunda’ at the end of T3 – currently dedicated to Qantas and QantasLink flights – would be extended to a new ‘western concourse’ bridging the gap to the western end of T2.
The result would be a horseshoe-shaped precinct bringing regional, domestic and international flights under one roof.
12 new 'swing gates' will be added across T2 and T3.
Joining T2 and T3 “will be the most significant development at Sydney Airport since the Olympics,” says Sydney Airport CEO Scott Charlton, “and will unlock greater capacity across all terminals, more efficient use of our runways, and ultimately get passengers from the ground and into the air more quickly.”
The T1 international terminal would also be expanded at both ends to gain additional gates, lounges and more space for retail and dining.
Sydney Airport is expected to welcome more than 72 million passengers every year – an increase of 75% from today – with international passengers making up more than half of that number, up from 40% today.
Of course, this isn’t the first time that Sydney Airport has talked of running international flights from T2 and T3.
An earlier proposal to transform T3 into a super-hub for Qantas and its Oneworld partners.
In 2011, the airport’s 2033 Master Plan proposed that both T1 and T2/T3 become “integrated terminals for international, domestic and regional airlines” with “swing gates which can be used for either international or domestic/regional operations at different times of the day.”
This resulted in a scrapped proposal to create two alliance-based ‘mega-terminals’ combining domestic and international operations – with Qantas and its Oneworld partner airlines at the T2-T3 hub, while Virgin Australia, Star Alliance and presumably SkyTeam would have been located at T1.
The 2039 Master Plan, released in 2019, likewise talked up a combined T2/T3 which would “integrate international, domestic and regional operations.”

As long as they design it so you don't need to go through security twice, like at Perth!

As long as the liquids rule for international flights applies, two security checks will be required.

They could quite easily build a separate entrance and security for international departures. Like repurpose the entrance at the left side of QF check-in for international security, with some stairs up to a new second floor for international departures. Or build something over near the valet check in. I'm sure theres a solution.

QF would then also need to replicate the lounge(s) in the new international area, as well as duty free.

Like at NRT T2 where domestic flights have an entirely separate check in, security and baggage collection area closer to the swing gate area.

You will have to "go through security twice" because there are different rules for LAGs on domestic vs international flights. So there will be the main security scan at the entrance to 'airside' of the terminal just like there is now, and then a secondary scan to international standards at the swing gate or the 'international wing' between T2 and T3, or something like that.

I like the sound of this, at least it reduces the pain of the inter-terminal transfer.
Obviously a lot of Qantas Platinum frequent flyers will lose access to the First Lounge at T1 if they are heading to NZ and their NZ flights leave from T3. Be interesting to see how Qantas manages this, I think upgrading the T3 Business Lounge to be a lot better will help but it will never be a touch on the T1 First Lounge.
But great for Virgin Australia, I imagine all international Virgin Australia flights except for the QR777s will depart from T2, better for aircraft utilization and passenger convenience and also lets them use the Business Lounge for an international VA flight.
By the looks of the diagram the 'missing link' between T2 and T3 will become an 'international wing' with the swing gates and maybe a few other swing gates at the very end of each terminal adjoining this.

How many times have they announced this now? Integrated alliance terminals make common sense so passengers don't need to schlep from T1 to T2/3 or the other way round to transfer. Which almost certainly means it won't happen...sigh.

I just don’t want to have to get a bus for a regional flight especially from Canberra. Sometimes the bus trip takes half the flying time….

No doubt if Qantas are involved there's going to be issues.
Discussions been going on for over a decade now so I am not even confident this will even happen in my lifetime.

I find it difficult to believe anything positive about Sydney airport.
Living in Adelaide, I am 'lucky' to be able to use Melbourne for any flights unavailable here.
I will not use Sydney ever again because it is just unacceptable.
