Australian Airport Sets Global Security Standard, Leaving TSA's $781 Million Rollout in the Dust
Sydney Kingsford Smith International Airport has completed a government-mandated security overhaul, introducing new features such as mandatory body-scanner screening and CT scanners that allow passengers to keep liquids and electronics in their bags. The upgrades have increased passenger throughput and reduced screening time by 50%. The Australian Government's $2 billion spending aims to improve and speed up security checks for carry-on luggage and passengers.
The Australian airport that's setting the global security standard has left the TSA's $781 million rollout in the dust. Sydney Kingsford Smith International Airport has completed a government-mandated security overhaul, introducing new features such as mandatory body-scanner screening and CT scanners that allow passengers to keep liquids and electronics in their bags.
## The TSA's $781 Million Scanner Rollout
The TSA is completing a $781 million scanner rollout with CT capabilities, but it doesn't match the work put in by the Australians. The rollout includes 469 base and 469 full-size systems, which will replace traditional X-ray machines. The full-size system features automated screening lanes and bin return, high-threat containment, and more. The technology also allows passengers to leave their liquids and electronics in their bags.
| Feature | TSA's $781 Million Scanner Rollout | Sydney Kingsford Smith International Airport | | --- | --- | --- | | Scanner Type | CT | CT | | Number of Systems | 469 base, 469 full-size | Not specified | | Automated Screening Lanes | Yes | Yes | | Bin Return | Yes | Yes | | High-Threat Containment | Yes | Yes | | Liquids and Electronics in Bags | Yes | Yes |
## The Australian Security Upgrades Impact Bag And Person Checks
The Australian Government's $2 billion spending aims to improve and speed up security checks for carry-on luggage and passengers. Sydney Airport leads the charge, with mandatory body scanner screening for all passengers. New CT scanners are also part of the measures, allowing passengers to keep their liquids, electronics, and aerosols in their bags.
| Terminal | Number of New Security Lanes | | --- | --- | | International Terminal | 15 | | Terminal Two | 7 |
The International Terminal has brought in 15 of the three new high-tech security lanes, while Terminal Two includes seven new screening lanes. The Terminal Two changes are part of a broader $200 million redevelopment, which aims to cut the curb-to-gate journey to just 15 minutes.
## The Developments Have Also Made Security Faster
The Sydney Airport upgrades have achieved this by doubling passenger throughput and increasing capacity by nearly 30%. The cuts to queues and congestion have already benefited millions of flyers. Passengers are enjoying the expedited security experience, with Sydney Airport claiming that 99.1% of international travelers and 99.9% of domestic travelers now clear security in under 10 minutes.
| Year | Passenger Numbers at Kingsford Smith | | --- | --- | | 2013 | 36.4 million | | 2014 | 38.1 million | | 2015 | 39.8 million | | 2016 | 41.5 million | | 2017 | 43.3 million | | 2018 | 44.8 million | | 2019 | 46.3 million | | 2020 | 24.5 million | | 2021 | 30.8 million | | 2022 | 35.6 million |
## Work Is Also Underway At Australia's Other Major Airports
As with the TSA investment, Australian spending is not all going to a single airport. Sydney Airport is leading the way, but destinations like Brisbane Airport and Melbourne Airport are close behind. Brisbane Airport has launched its Domestic Airport Transformation program, which introduced five new CT lanes in October 2025. The same technology was expanded to the International Terminal by the end of 2025.
| Airport | Passenger Numbers (last 10 years) | | --- | --- | | Brisbane Airport | 2013: 18.1 million, 2022: 23.5 million | | Melbourne Airport | 2013: 30.5 million, 2022: 37.8 million |
Similar steps have been taken at Melbourne Airport, with new body scanners and CT lanes for baggage. Across all these airports, increased traffic from airlines such as Turkish Airlines, Etihad Airways, Virgin Australia, and Qatar Airways raised passenger numbers. All major airports in Australia were in a race against time to have the technology ready.
## Western Sydney Airport's Approach Has Given New Impetus For Kingford-Smith's Security Upgrades
Sydney Airport will soon no longer be the only place you can fly from in the city. The $14 billion Western Sydney Airport is scheduled to open in October 2026, located around 31 miles (50 km) west of the city center. If these airports have overlapping routes and airlines, it will be a battle of convenience that defines which option passengers use.
## The UK Is Another Country Concentrating On CT Upgrades
It is far from just Australia and the US that is spending a huge amount of money on CT bag scanning technology to improve the safety and efficiency of their airport security systems. In the UK, Vinci Airports has worked with Belfast International Airport, Edinburgh Airport, and London Gatwick Airport to roll out CT systems in the security lanes. Gatwick now has 19 security lanes, while Edinburgh and Belfast both have eight, an increase of two in each case.
| Airport | Number of Security Lanes (pre-upgrade) | Number of Security Lanes (post-upgrade) | | --- | --- | --- | | Gatwick | 17 | 19 | | Edinburgh | 6 | 8 | | Belfast | 6 | 8 |
