Saint in love with wealth gets exotic birds (9)
I believe the answer is:
ostriches
'exotic birds' is the definition.
(birds native to Australia)
'saint in love with wealth' is the wordplay.
'saint' becomes 'st' (abbreviation).
'in' is an insertion indicator.
'love' becomes 'o' (love means zero in tennis).
'with' means one lot of letters go next to another.
'wealth' becomes 'riches' (synonyms).
'o'+'riches'='oriches'
'st' inserted inside 'oriches' is 'OSTRICHES'.
'gets' is the link.
(Other definitions for ostriches that I've seen before include "Fast-running flightless birds" , "People not facing the reality" , "Largest living birds" .)
