A couple of things for perspective;
It is about the same land area as the lower 48 but has the population of the LA/San Diego Metroplex.
There is more miles of limited access, divided freeway in the LA basin than there is on the entire continent of Australia.
You would be damned hard pressed to find a spot in the lower 48 that was more than 70 air miles from a McDonalds.
(The above claim was made in a thread on DU a while back and I thought - bullshit. I've driven all over this land and across and through some of the remotest parts of it. But you know what? It's true. There are very few if any places in the continental US that are more than 70 air miles from a Micky Dees)
Not the case in Australia. Not even close. There are places where you could walk for days and days without seeing evidence of a human ever having been there before. Not a fenceline, not a tire track or a foot print or electric powerlines. NOTHING.
And then there are places like this;
The beach at Surfers Paradise, in Queensland. It could be any resort beach town in the world. (Got to Surfers several times in the 1990's for the Indy Car race.)
And there are roads in the outback like this;
That stretch for hundreds of miles.
That by the way, is a highway. Deep red dust. Sometimes the road is hard packed, sometimes it has a surface like a washboard. Almost all of it is open range land.
Comparatively few miles of the roads in the interior are paved and hardly any of it is fenced to keep animals off like it is here in the states. You're as likely to hit a Kangaroo as you are a Shorthorn steer.
If I could, I would emigrate there in a heartbeat.
