Australia Pacific Airports (Melbourne) has officially launched the terminal 4 at the Melbourne Airport.
The new domestic terminal, which already started operations few months ago, is a part of the $550m Southern Precinct project under the $1bn phased-expansion programme.
The Southern Precinct project also includes construction of an elevated cross concourse and a new Pier G, and upgrade of the existing buildings.
The phased-expansion programme forms part of Melbourne Airport's transformation project, which intends to invest up to $10bn over the next 20 years.
Melbourne Airport CEO Lyell Strambi said: "This official opening of T4 is another milestone in the transformation of Melbourne Airport - which has responded to the growth of domestic aviation in Australia.
"Terminal 4 provides our passengers with a new level of service, and our airline customers the room to keep growing their business to meet demand for air travel."
Capable of handling ten million passengers a year, the new terminal will be the home for airlines, including Tigerair Australia, Jetstar and Regional Express (Rex).
Located to the south of Terminal 3 built, the terminal features baggage handling and re-claim facilities, staff amenities, check-in kiosks and associated infrastructure, retail areas and connections to existing concourses.
Australia Federal Treasurer Scott Morrison said: "The new Terminal 4 is a great example of modern infrastructure and it will help to drive jobs here in Victoria and beyond."
In 2013, Australian Pacific Airports Melbourne selected Leighton Contractors to build a airline terminal and an integrated transport facility at Melbourne Airport.
