I saw this rock in the rock pool and it gave me cause to think of something very small (us) moving through something very large and empty (the outback).
The vast majority of Australia’s population is found hugging the coast (around 18 million of Australia’s 20 million population). There are large towns (with a population of, say, 20,000 – 50,000) within a couple of hundred kilometres of the coast, then, a couple of hundred kilometres further inland, towns of less than a few thousand inhabitants. [I’m generalising, but you get the idea].
Don’t even think of obtaining mobile phone coverage in the arid interior. No specialist medical services. No supermarkets. No mains power (diesel generators are common). No water treatments plants. No daily newspapers. No radio or TV (though satellite TV is not uncommon). I love it!
