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. Several times last month I (QF) have been at the very last one (25 or 26 cant remember which is the last one but JQ used to occupy it). This may have to do with the dual occupancy of International/Domestic as when there is SQ, MH and NZ there at the same time it closes off quite a few of the most convenient gates 18-22. I have departed from the very furthest DJ gate and boy thats a hell of a hike.
Just FYI was told by ground staff that Adelaide Airport terminal has the same ground area size as Sydney. I thought I was walking a lot there.
