Probably shouldn't have bought into this thread as I haven't been near the computer much, anyway time for some big clues;
The indigenous ceremonial ground in the photo is adjacent to a track that accesses a remote coastal/estuary area where two rivers meet. It is accessed through private property which is currently for sale. The track is named after a small indigenous community which is close to the estuary area. The track was put in in the 1970s as a condition imposed by government on someone who wanted to establish a cattle station in the area- he was killed by a crocodile some time later so that should help with the general latitude at least. The property through which this track is accessed shares a name with a member of the British royal family. Many people on this forum will have stayed at this particular property, although not many may have traveled this track as part of their trip.
The name of the track's destination is written (with an angle grinder!) on the ute tailboard above our heads in the third photo.
