The town where I lived for my high school years was 1800km away from the nearest city (Perth) and about the same to the next one in the other direction (Darwin). Only one decent sized town around 100k pop. along that whole coastline. The next town of any size to the north was 600km away. With one petrol station along the way and pretty much nothing else except kangaroos.
We would drive for two hours just to have fish and chips, and a swim at a different beach.
