I believe the answer is:
poignant
'sharp' is the definition.
(thesaurus)
'fielder catching good new australian' is the wordplay.
'fielder' becomes 'point' (I've seen this before).
'catching' is an insertion indicator.
'good' becomes 'g' (abbreviation).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'australian' becomes 'A'.
'g'+'n'+'a'='gna'
'point' placed around 'gna' is 'POIGNANT'.
(Other definitions for poignant that I've seen before include "Deeply moving - no taping (anag)" , "Sharply upsetting" , "Arousing sympathy, moving to the feelings" , "Evoking sadness or regret" , "Touching - gin on tap (anag)" .)
