Bird seen around Australia, very remote creature (7)
I believe the answer is:
martian
'very remote creature' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'bird seen around australia' is the wordplay.
'bird' becomes 'martin' (martin is a kind of bird).
'seen around' indicates putting letters inside.
'australia' becomes 'A' (abbreviation for Australia).
'martin' enclosing 'a' is 'MARTIAN'.
Can you help me to learn more?
(Other definitions for martian that I've seen before include "Sci-fi alien" , "Invader in The War of the Worlds (H. G. Wells)" , "Sci-fi character" , "Green man from the Red Planet" , "One of H. G. Wells's invaders" .)
