Teacher organised a tour to central Austria (5)
I believe the answer is:
tutor
'teacher' is the definition.
(tutor is a kind of teacher)
'organised a tour to central austria' is the wordplay.
'organised' indicates anagramming the letters.
'to central' means to look at the middle letters.
The centre of 'austria' is 't'.
'tour'+'t'='tourt'
'tourt' with letters rearranged gives 'TUTOR'.
(Other definitions for tutor that I've seen before include "train" , "Individual teacher" , "Personal coach" , "Trout (anag)" , "Teach" .)
