Praise Australian cutting orchard fruit (8)
I believe the answer is:
applause
'praise' is the definition.
(thesaurus)
'australian cutting orchard fruit' is the wordplay.
'australian' becomes 'aus' (common abbreviation).
'cutting' is an insertion indicator (some letters cut their way into a word).
'orchard fruit' becomes 'apple' (I've seen this before).
'aus' going within 'apple' is 'APPLAUSE'.
(Other definitions for applause that I've seen before include "Acclamation" , "round, perhaps?" , "giving a hand?" , "Appreciative claps" , "Clapping US appeal?" .)
