interior regions of Australia": The Outback
"Like the above, but not as remote": The . . . Inback?
I missed it too... but I guessed "fair" right! I was looking away when typing it (cat business) and when I looked back to the screen and saw it was accepted, I think I made a pretty weird face haha.
12003 points, 13000 here we come ( in about 1,5 year haha)
Didn't know the Nullarbor plain one though...
Also, there's no real requirement for "the bush" to be remote, vast, or interior. Pretty much any National Park, forest (regardless of size or location) or grassland would count, although "the bush" is sometimes used as a generality for non-desert regional Australia.
I grew up playing in "the bush" which I reached from my house in Sydney by walking to the end of my street. It's really just a term for any reasonable chunk of undeveloped land, so as an Australian, that was actually the hardest question for me - I had to think "What misconceptions might an American have?" to get it.
Maybe reword the question: "Plain in South Australia named after its lack of trees" - "Nullarbor"
Rewording the question so that 'Nullarbor' is the answer you have to give, stops it from being obvious. That's the point.
