Australian animal (8)
I believe the answer is:
kangaroo
'australian animal' is the definition.
(informal term for a kangaroo)
This is the entire clue.
(Other definitions for kangaroo that I've seen before include "Native marsupial Down Under" , "Would anorak go on the animal?" , "Marsupial (both parts 4's friends)" , "Australian animal -- a no-go ark (anag)" , "Bounding marsupial" .)
