New names at Melbourne Airport
From 1 July 2005, the terminals at Melbourne Airport will be renamed.
The Qantas domestic terminal will become Terminal 1 (T1).
The international terminal will become Terminal 2 (T2).
The multi-user southern domestic terminal will become Terminal 3 (T3).
You'll see these new names on the road signs, and on signs in car parks and inside the terminal.
