Binghi,
here ya go. Whilst you're at it, why not apply to the Dept under the freedom of information act for a copy of their special event permit. If indeed they had or were even required to have one. Given that the arrival was on the RAAF Fairbairn side of the field, I'd suggest that the requirements for ASICs and airside access differ to those at the civilian apron.
