Here is an article from the QantasLink "Spirit" Inflight Magazine for Autumn 2013:
"QantasLink is planning a move of terminals from Sydney Airport's T2 to the main T3 Terminal used by Qantas mainline services. The move will provide considerable benefits for QantasLink travellers using Sydney Airport giving easier access for connections on other Qantas Domestic flights and access for Qantas Club members to the Club Lounge and Business Lounge in T3.
The enhanced customer experience for QantasLink passengers will also allow for more streamlined operations for the airline. A team from the airline's engineering, catering, ground operations and customer experience divisions have been working together to find the best way to integrate QantasLink's operations into T3. The integration is planned to take place during the second quarter of 2013."
Any info on the T2 Lounge in that article?
