Bird on Australian coins (3)
I believe the answer is:
emu
'bird on australian coins' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for emu that I've seen before include "Ostrich-like bird" , "Aussie runner" , "Big bird" , "Flightless bird of Australia, like ostrich" , "Hull's character" .)
