Tiny South Pacific nation (5)
I believe the answer is:
nauru
'tiny south pacific nation' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nauru that I've seen before include "Small Pacific republic" , "[OCEANIA] location" , "Pacific coral island republic, once rich in phosphates" , "SW Pacific republic" , "Fairground carousel" .)
