Carnage in great lush butchery (9)

I believe the answer is:

slaughter

I'm a little stuck... Click here to teach me more about this clue!

'butchery' is the definition.
(I know that butchery can be written as slaughter)

'carnage in great lush' is the wordplay.
'great lush' can be anagrammed to 'SLAUGHTER'.
Though, I'm not sure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for slaughter that I've seen before include "Killing (of farm animals)" , "best" , "Kill cruelly" , "Murder" , "Glare thus to cause bloodthirsty killing" .)

I've seen this clue in the Sydney Morning Herald.
