Hi 5tarman,
Depending on Traffic that 30/60 min away might be maybe 30-50km from the CBD. If so then anywhere in a light blue/Blue/violet/grey/charcoal-black zone would be possible in the
lightpollution.info excerpt image below.. The light blue border I checked the sky brightness levels showed an SQM of 21.8 which is reasonably dark, although there's certainly much darker on the map in the grey & charcoal/black shaded areas.
To put that in to perspective that SQM reading of 21.8 is equivalent to a sky brightness of 204 µcd/m2, which isn't that far from the natural (perfect dark site) sky brightness of around 170 odd µcd/m2 and a far cry from the Sky brightness in the Adelaide CBD which is
20 times higher with a brightness of 4060 µcd/m2 !!!
So depending on where you are, perhaps just Travel East from the CBD. As for safety, who knows? Perhaps travel with friend/s to a remote area or friend's farm, maybe even stay at a local motel and setup next to your room without external lights about. As an aside, we did a Moto tour of SA, and found Kangaroo Island very dark.
Good luck in your travels....
Best
JA
