Sue is a different person from Victoria, perhaps (6)
I believe the answer is:
aussie
'person from victoria perhaps' is the definition.
I can't tell whether this definition defines the answer.
'sue is a different' is the wordplay.
'different' is an anagram indicator (letters placed in a different order).
'sue'+'is'+'a'='sueisa'
'sueisa' with letters rearranged gives 'AUSSIE'.
Can you help me to learn more?
(Other definitions for aussie that I've seen before include "Sheila from Sydney, perhaps?" , "One from down under" , "Adelaide native?" , "Someone from Sydney? (slang)" , "Someone from Melbourne, perhaps (slang)" .)
