Opened on December 8, 1991, to much fanfare, the complex is designed to handle up to 1.2 million passengers per year.
And with a roof area covering over 13,000 square metres, it is still one of Central Australiaâ€™s largest commercial buildings.
Tomorrow, Member for Lingiari Warren Snowden MP, will return to the airport for its anniversary, 25 years after he formally opened the new terminal in 1991.
The Honourable, Warren Snowden, MP, will unveil a brass plaque to commemorate Alice Springs Airport terminalâ€™s two and a half decades to a crowd of VIPs.
Within its 25 years, many significant changes have taken place both within the new terminal and the broader national aviation scene.
Undercover parking, a significant investment in solar power and landside access are notable developments, in addition to a continuous growth of food and beverage outlets within the terminal.
The number of passengers through Alice Springs Airport continues to increase steadily, with approximately 600,000 passengers in recent years.
According to the current master plan for the airport, this is expected to rise to 750,000 by 2035.
The gateway's general manager, Dave Batic, says: "I am proud to acknowledge all past and present management and staff for continuing to enhance and maintain this magnificent airport terminal facility.â€ť
