Research syndicate to evaluate the commercial value of integrated terminals in Australia
The Mercurius Group, design firm Populous, design and engineering firm Arup, plus Adelaide and Gold Coast airports, are supporting bespoke consumer research into domestic terminal retail spend and shopping behaviour at integrated domestic and international terminals.


AUSTRALIA. Leading airport commercial advisory firm The Mercurius Group has established a stakeholder syndicate to research the commercial benefits of integrated domestic and international passenger terminals in Australia.
Partners include Mercurius, global design firm Populous, design and engineering firm Arup, along with Adelaide and Gold Coast airports. The syndicate is funding bespoke consumer research into domestic terminal retail spend and shopping behaviour among international passengers within integrated terminals.
THINK Global Research, a consumer research specialist in the airport sector, will produce a White Paper for presentation at the Australian Airports Association Retail & Commercial Forum in Sydney on 21-23 July. The Forum is organised by a joint venture of the Australian Airports Association, The Mercurius Group and The Moodie Davitt Report.
Historically, most Australian airports have had separate domestic and international terminals, but some, like Adelaide and Gold Coast, have adopted integrated terminal strategies. An integrated terminal provides a shared sterile retail area after domestic security for all passengers and visitors.
To access the international gates, international passengers are required to pass through additional borders (OCP) and security screening (PLAGs). This extra screening, including the need to requeue 90 minutes before departure, reduces the time international passengers spend in the domestic terminal, limiting their potential retail and F&B spend.
The integrated terminal approach can optimise gate capacity at lower cost by using swing gates, which can switch between domestic and international flights. Other airports with integrated terminals include Perth (T3/T4), Darwin, Hobart, Sunshine Coast, Newcastle and Canberra, with Perth also planning a broader terminal integration. Integrated terminal projects are also being explored at major airports in Australia and New Zealand.
As international passenger volumes at airports such as Adelaide and Gold Coast are not yet sufficient to support a full commercial programme in the embedded international areas (beyond duty free and limited F&B offers), the domestic terminal plays a crucial role in meeting these passengers’ retail needs.
The research aims to identify strategies to increase retail spend by addressing these challenges and finding solutions to enhance international passenger engagement in the domestic area of integrated terminals.
One solution could be the introduction of a Common Departures Lounge operation to further improve the commercial performance. The Common Departures Lounge concept, implemented in other markets, screens all departures passengers to the international standard and provides a common retail and gate area for all departures. The physical Border Force screening is replaced with alternative technological measures.
Commenting on the project, Matt Findlay, Head of Aviation – Australia & New Zealand for Populous said: “Integrated terminals are a hot topic in the terminal design space in Australia, with a number of airports exploring their potential. Populous recognises the significant commercial benefits that integrated terminal designs could bring to airports, so we’re delighted to be part of this syndicate, researching ways to improve outcomes for all stakeholders.”
Arup Principal Jim Peacock said: “Integrated terminals make a lot of sense from an airport planning perspective, but the current requirement to double security screen international passengers can be a barrier to efficient airport operations – using up space, adding cost and eating into passenger dwell time. This research will further our collective understanding of the merits of integrated terminals and shape our understanding of the Common Departures Lounge transition.”
The syndicate’s two airport members highlight the benefits they expect from the research. Adelaide Airport Head of Retail Ilona Rose said: “Adelaide Airport was one of the first—if not the first—integrated terminal in Australia. We have long believed that international passengers play a significant role in our domestic terminal retail programme, but until now, we’ve lacked the concrete data to support this theory. Additionally, we need more in-depth insights into how much double screening impacts international passengers’ ability to fully benefit from our extensive retail and F&B programme.”
Queensland Airports Limited Chief Commercial Officer Adam Rowe said: “Maximising the potential of international passengers within an integrated terminal environment is a complex dynamic, with a number of interconnected constraints. The starting point for improved outcomes is a deeper understanding of our customers’ retail spend and shopping behaviour in our current retail environment. This will help us optimise our strategies and improve customer experience as we build for the future.”
The Mercurius Group Managing Director Ivo Favotto said: “Mercurius is excited to bring these stakeholders together to ensure we get the best outcomes from this project. Architects, terminal planners and airports all have a vested interest in this process as the industry works towards both optimal integrated terminal design and commercial success.”
AAA CEO Simon Westaway said: “We are delighted that the Retail & Commercial Forum is being used to deliver bespoke and insightful research on key topics of interest to both airports and the airport commercial community alike. It highlights and strengthens the value of attending this event.”
