End of combat that's unfortunate for indigenous Australians (6)
I believe the answer is:
koalas
'australians' is the definition.
Although both the answer and definition are plural nouns, I cannot understand how they can define each other.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for koalas that I've seen before include "Tree-climbing marsupials in Australia" , "Cute animals" , "Australian tree-climbing marsupials" , "Australian arboreal marsupials" , "Australian tree-climbing mammals" .)
