N82GG returned to Rockhampton Airport later in the day.
As shown in the photo above, the LearJet has a camera on the forward-starboard side of the fuselage. It has been reported that the aircraft is operating aerial mapping sorties for Nearmap - the international provider of high resolution aerial imagery.
UPDATE! On Saturday 14 May, it looks like N82GG departed Rockhampton Airport and returned South to the Gold Coast.
Sincere thanks to 'IAD' for sending through these great photos!
