Prune around Aussie bush, but not the front (3,4)

I believe the answer is:

cut back

'prune' is the definition.
(synonyms)

'around aussie bush but not the front' is the wordplay.
'around' becomes 'c' (abbreviation for 'circa').
'aussie bush' becomes 'outback' (the Australian outback).
'but not the front' means to remove the first letter.
'outback' with its first letter taken off is 'utback'.
'c'+'utback'='CUT BACK'

(Another definition for cut back that I've seen is " Economise".)

I've seen this clue in The Telegraph.
