In Australia, a discarded defender? (7)
I believe the answer is:
outback
'in australia' is the definition.
('outback' is part of 'australia')
'a discarded defender?' is the wordplay.
'a discarded' becomes 'out' (I can't explain this - if you can you should give a lot more credence to this answer).
'defender?' becomes 'back' (left-backs and right-backs are football defenders).
'out'+'back'='OUTBACK'
Can you help me to learn more?
(Other definitions for outback that I've seen before include "Remote areas of Australia" , "Remote Australian area" , "somewhere remote" , "Bush country of Australia" , "Australian wilderness" .)
