Australian anteater (7)
I believe the answer is:
echidna
'australian anteater' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for echidna that I've seen before include "One preying on the workers" , "Little animal" , "Such a beast" , "Creature with spines" , "Spiny egg-laying Australian mammal" .)
