Sydney Airport has appointed construction company Multiplex to provide early contractor involvement (ECI), construction planning and delivery expertise for the development of its T2-T3 terminal project.
The appointment will support Sydney Airport as it prepares the Major Development Plan for the project, which is expected to add new terminal space and 12 swing gates capable of handling both domestic and international operations.

The development is also intended to improve connections between the airport’s terminals and provide additional capacity as passenger numbers increase.
Sydney Airport Group Executive, Planning and Delivery, Paul Willis, said:Bringing Multiplex into the project at this stage gives us valuable construction and delivery expertise as we continue to develop the Major Development Plan.
This is a highly complex project in the heart of a live airport precinct. Early collaboration between the airport, designers and contractor will help us test how the project can be built and staged safely and efficiently, while minimising impacts on passengers, airlines and airport operations.
Multiplex has a strong track record delivering complex infrastructure and major projects, and we look forward to working together to progress a terminal development that supports Sydney Airport’s long-term growth and delivers a better experience for passengers and airlines.
The project will be delivered within an operational airport precinct, requiring construction and staging plans to account for passengers, airlines and ongoing airport operations.
The appointment follows Sydney Airport’s selection of Grimshaw and Mott MacDonald as lead consultants for the T2-T3 project. Grimshaw is responsible for the architectural design, while Mott MacDonald is leading engineering.
The T2-T3 terminal project forms part of Sydney Airport’s planned A$6 billion capital works programme over the next five years.
The programme is intended to support Sydney Airport’s longer-term growth plans, with the airport forecasting demand of up to 72 million passengers a year by 2045.
