Independent radicalism on beaches in the Pacific? (7,7)

Ross

I believe the answer is:

solomon islands

I'm a little stuck... Click here to teach me more about this clue!

'beaches in the pacific?' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.

'independent radicalism on' is the wordplay.
I cannot quite understand how this works, but
'independent' could be 'i' and 'i' is found within the answer.
'on' is within the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for solomon islands that I've seen before include "Country" , "Pacific state" , "part in South Pacific" , "Pacific location" .)

I've seen this clue in the Sydney Morning Herald.
