For the keen, seeking the ultimate (with respect to seeing):

In the mean time, I have settled (figuratively speaking) on a site 300km North East of Perth, in the wheat belt. The nearest town (of 100 people) is 30km away.
When Peter Reid came over and visited a couple of years ago, he rated the seeing, transparency and sky brightness as being better than Connabarabran.
We planted 12,000 trees and understory 5 months ago.
Accommodation consists of a caravan, a couple of 40' sea containers, solar with batteries for power and enough capacity to run an air-conditioner in summer and a fridge year round, basic toilet, hang a water bag in the tree if you want a shower, most of the niceties were curb side collection (including a pot belly stove and a leather lounge suite picked up from the side of the road - gotta love the payment plan on freebies)
Austere, but it's marvellous to be up there and gutting when it's time to come home. Spending time there makes you realise how much of the trappings of modern life you
don't actually need.
Local cops and townsfolk are a different breed from your average city slicker.
Still have to put a roof over the sea-tainers (with gutters) for the two big assed water tanks..
Might even be remote enough to avoid the zombie apocalypse/WW3, etc.
And it just occurred to me that there is a further blessing... it's a fairly dry area (250mm of rain a year) So no mosquitos.
