Return journey to part of Australia (7)
I believe the answer is:
outback
This might be a double definition.
'return journey' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'to part of australia' is the second definition.
(the Australian outback)
Can you help me to learn more?
(Other definitions for outback that I've seen before include "Arid interior" , "Remote land in Australia" , "continental interior?" , "Remote areas of Australia" , "somewhere remote" .)
