Island's officer getting about (7)

I believe the answer is:

majorca

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

'island's' is the definition.
(I've seen this before)

'officer getting about' is the wordplay.
'officer getting' becomes 'major' (I can't justify this - if you can you should give a lot more credence to this answer).
'about' becomes 'ca' (abbreviation for 'circa').
'major'+'ca'='MAJORCA'

Can you help me to learn more?

(Other definitions for majorca that I've seen before include "Palma its capital" , "Largest Balearic Island" , "holiday resort" , "holiday destination ..." , "Main Balearic island" .)

I've seen this clue in The Telegraph.
