New recruit, Aussie native, beginner from Kalgoorlie that is (6)
I believe the answer is:
rookie
'new recruit' is the definition.
(a rookie is a new recruit or trainee)
'aussie native beginner from kalgoorlie that is' is the wordplay.
'aussie native' becomes 'roo' (short for kangaroo).
'beginner from kalgoorlie' becomes 'k' (I can't explain this - if you can you should believe this answer much more).
'that is' becomes 'ie' (abbreviation for id est, 'that is' in Latin).
'roo'+'k'+'ie'='ROOKIE'
Can you help me to learn more?
(Other definitions for rookie that I've seen before include "untrained soldier" , "inexperienced fighter" , "Raw recruit" , "Novice" , "new team member" .)
