Child prodigy from Australia found in shopping centre (6)
I believe the answer is:
mozart
'child prodigy' is the definition.
(Wolfgang Amadeus Mozart was a child prodigy)
'australia found in shopping centre' is the wordplay.
'australia' becomes 'oz'.
'found in' indicates putting letters inside.
'shopping centre' becomes 'mart' (large shopping complex).
'oz' placed within 'mart' is 'MOZART'.
'from' acts as a link.
(Other definitions for mozart that I've seen before include "Magic Flute composer" , "The composer can be found in an OZ mart" , "'Cosi fan tutte' composer" , "Wolfgang Amadeus . . . . . . 18th century Austrian composer" , "Wolfgang Amadeus of Salzburg" .)
