Australian peach brandy factory employee? (7)
I believe the answer is:
bottler
I believe this is a double definition.
'australian peach' is the first definition.
(bottler is Australian slang for something great)
'brandy factory employee?' is the second definition.
(someone bottling drink)
(Other definitions for bottler that I've seen before include "Person or machine filling drink containers" , "One putting drink in containers" .)
