Good French offer returned on every resort (5,5)
I believe the answer is:
bondi beach
'resort' is the definition.
(I have seen 'Australian resort' mean 'bondi beach' so perhaps 'resort' could also mean 'bondi beach')
'good french offer returned on every' is the wordplay.
'good french' becomes 'bon' ('good' in French).
'offer' becomes 'bid' (bid is a kind of offer).
'returned' is a reversal indicator.
'on' says to put letters next to each other.
'every' becomes 'each' (synonyms).
'bid' backwards is 'dib'.
'bon'+'dib'+'each'='BONDI BEACH'
(Other definitions for bondi beach that I've seen before include "coastal strip" , "Australian resort" .)
