I had found OzSky before the trip. What I had to do on this 1st trip was have my wife also end up with a vacation. So the OzSky sounded fantastic from my personal astronomical perspective but the Arkaroola covered our common desire to see the more arid part of Australia by day (than Sidney/Blue Mountains of a prior trip).
Have taken note of OzSky to be sure and had viewed a web page on it a few months before my trek and will keep that in mind for future treks or to tell others about as the south sky is discussed.
Well ... since I am 'in Rome' I will end with ...
No Worries,
