Women on low return are back in range (7)
I believe the answer is:
woomera
'range' is the definition.
(I have seen 'range of Australians' mean 'woomera' so perhaps 'range' could also mean 'woomera')
'women on low return are back' is the wordplay.
'women' becomes 'w' (standard abbreviation).
'on' is a charade indicator (letters next to each other).
'low' becomes 'moo' (both can mean to make the noise of a cow).
'return' says the letters should be written in reverse.
'back' shows that the letters should be reversed in order.
'moo' in reverse letter order is 'oom'.
'are' written backwards gives 'era'.
'w'+'oom'+'era'='WOOMERA'
'in' acts as a link.
(Other definitions for woomera that I've seen before include "range of Australians" , "South Australian town" , "Missile test site in South Australia" , "Aboriginal throwing stick; Australian rocket range" , "Austr. rocket range" .)
