Telephones about island rebellions (7)

I believe the answer is:

risings

'rebellions' is the definition.
(I know this)

'telephones about island' is the wordplay.
'telephones' becomes 'rings' ('ring' can be a synonym of 'telephone').
'about' indicates putting letters inside.
'island' becomes 'is' (geographical abbreviation).
'rings' enclosing 'is' is 'RISINGS'.

(Another definition for risings that I've seen is " rebellious actions".)

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