Australian "bear" (5)
I believe the answer is:
koala
'australian bear' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for koala that I've seen before include "Cuddly Australian marsupial" , "Eater of eucalyptus" , "Arboreal Australian native" , "Marsupial climber" , "small bear" .)
