Hey DW,
Just to give an idea of our size verses our population (approx. 20 million people).
If you have a look at the first map, in the center is Alice Springs, where I grew up and ,ironically George Kolef had a shop at the same time. If only I'd been older, known what I wanted to be when I grew up , and knew he was there
It's a town of 30,000. There are really only two roads out, that a normal car can drive on (as in sealed and not needing high clearence and winches

) ,to get to other towns and the coast (a minimum of 1,450kms away).
Ayers Rock (always associated with the Alice) is 434kms away! A 4-5 hour trip.
The next town north is Tennant Creek, around 6,000 people (I've marked all these in), 505kms away. Katherine ,5,000 people, another 650kms.
To get to Mt. Isa, the next town/city (on your way ,the only 'direct' way, to the east coast. Refer to 'winches' note above) you have to get to Tennant first, then east another 600ish kms. Towns are only 3-400kms apart after that, until you get close to the Queensland coast where they might be only 100kms
If you go south from Alice the next town is Coober Pedy (opal mining), 5,000ish, and is over 600kms away.
There are *no* towns east or west of Alice.
I spent quite a while a week ago trying to explain to a Danish tourist (with maps) this situation, and that, apart from a pub/hotel with fuel every 200kms or so, there isn't anything in between ( quote "There are no cities? Just nothing?" she asked. The distance to Ayers Rock was the size of Denmark with 5million people in it, she told me. Now I have trouble getting my head around *that*).
The whole Northern Territory has a population of around 350,000 (mostly in Darwin)and is a single voting electorate (covering desert/arid, through to tropical/monsoonal).
Victoria though has approx. 4 million (not sure how they fit them all in), 3 of which live in Melbourne. In fact, of Australia's 20 million residents, over 50% live in it's 8 capital cities. I don't know why
Out of time.
Hope this has been enjoyable.
Cheers
Duncan
