Stand after knock out in the manner of Australian native (5,4)
I believe the answer is:
koala bear
'australian native' is the definition.
(animal native to Australia)
'stand after knock out in the manner of' is the wordplay.
'stand' becomes 'bear' (both can mean to tolerate or endure).
'after' says to put letters next to each other.
'knock out' becomes 'ko'.
'in the manner of' becomes 'a la' (e.g. chicken a la King).
'ko'+'ala'='koala'
'bear' after 'koala' is 'KOALA BEAR'.
(Other definitions for koala bear that I've seen before include "Marsupial climber" , "Eucalyptus eater" , "Aussie tree-hugger" , "Creature" , "Australian animal" .)
