Australia's largest city (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
sydney
'australia's largest city' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sydney that I've seen before include "NSW's capital" , "Antipodean city" , "Australian port" , "2000 Olympics hosts" , "City with famous harbour bridge" .)
