When I have been in ADL recently they have been parking QF side, about gate 23. A few months earlier they were the DJ side.
Adelaide airport is a Common User Terminal. There isn't technically a "QF" or "DJ" side as such.. AAL operate and run the terminal and allocate the bay allocations to aircraft. For operational convenience, the airport will try to keep the airlines in the same areas...however, as QF/DJ don't operate or assign their own bays - sometimes you will get QF parked down on the DJ end, and DJ aircraft parked on QF side. I do believe QF and DJ have an agreement with the airport to have a certain amount of bays allocations, however, it doesn't state on which bays. So airlines such as Tiger and others will get moved around to whichever bays are available at the time.
