US filmmaker somewhere in New South Wales having fish (6,7)

I believe the answer is:

sydney pollack

'us filmmaker' is the definition.
(director Sydney Pollack)

'somewhere in new south wales having fish' is the wordplay.
'somewhere in new south wales' becomes 'sydney' (Australian city).
'having' means one lot of letters go next to another.
'fish' becomes 'pollack' (pollack is a kind of fish**).
'sydney'+'pollack'='SYDNEY POLLACK'

I've seen this clue in The Times.
