If SQ were to start up, they would be putting forward a Premium Airline with business and first class travel. Apart from Melbourne, where they could lease some gates, what other terminals are they going to operate from. There is nothing left. In Brisbane, Virgin have bought the Ansett terminal, therefore only leaving the common user area, (hardly suitable for a Premium airline), In Sydney there is no telling how long that will take to sort itself out, (and SQ wont just jump in and pay the going rate just to get in quick), In Adelaide, Virgin will be moving in there later in the month of September, leaving the International SHED that they operate out of currently. Again, hardly high quality stuff.
There are a lot of guys on this forum who desperately want/think that SQ are about to start up just so they can get a job, but guys, don't go and get the A320 endorsement just yet.
