Englishman down under employing cleaner from the east (3)
I believe the answer is:
pom
'englishman down under' is the definition.
(Australian term for an English person)
'cleaner from the east' is the wordplay.
'cleaner' becomes 'mop' (something which 'cleans').
'from the east' says the letters should be written in reverse.
'mop' written backwards gives 'POM'.
'employing' is the link.
(Other definitions for pom that I've seen before include "Small dog (colloq.)" , "Shortened name for a breed of dog" , "Englishman in Australia" , "Pomeranian dog" , "best friend?" .)
