Carried round island in the Pacific (6)
I believe the answer is:
borneo
'island in the pacific' is the definition.
'carried round' is the wordplay.
'carried' becomes 'borne' (I've seen this before).
'round' becomes 'o' (round can mean a round object).
'borne'+'o'='BORNEO'
(Other definitions for borneo that I've seen before include "Island, part of the Malay archipelago" , "Large E. Indies island" , "Third largest island in the world" , "Lange island of the Malay archipelago" , "Island containing Brunei" .)
