“The feedback from travellers and airline staff has been fantastic,” he said. “It’s a giant leap from the 1990s to now.”

Amadeus senior vice-president Sarah Samuel said flexible cloud infrastructure and “advanced self-service options” would help improve passengers’ airport experience.

“Brisbane is a great example of an airport with a long-term transformation strategy that places the traveller at the heart of the experience,” Samuel said.

Downstairs,the space currently occupied by passport control and security screening will be taken by an expanded Lotte Duty Free,which will nearly double in size.

“There is nothing in the Brisbane store design that has similarity to any other place,” said Stephen Timms,chief executive of Lotte Travel Retail,Oceania.

“It will be a bespoke design capturing the flavour of Brisbane.”

Work in the terminal will be staged to minimise disruption,with the security screening changes due to be completed by December 2025,while other upgrades will likely be finished by 2027.

BAC would not reveal the cost of the work,other than to say it formed part of the airport’s $5 billion Future BNE strategy.

Also included in that strategy will be a third terminal,to be built between the existing domestic terminal and the new parallel runway.

De Graaff said planning for Terminal 3 was well under way.

“Eventually,we will integrate domestic and international passengers into this new facility,” he said.

“We need to determine whether this integration will happen from day one or in stages. What we know for sure is that sustainability and accessibility will be baked into the design of Terminal 3.”
