Last line out of Cuba and Jamaica, say (8)

I believe the answer is:

antilles

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

'cuba and jamaica say' is the definition.
I can't tell whether this defines the answer.

'last line out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'last'+'line'='lastline'
'lastline' with letters rearranged gives 'ANTILLES'.

'of' acts as a link.

Can you help me to learn more?

(Other definitions for antilles that I've seen before include "Organism's complete genetic material" , "archipelago" , "Caribbean islands" , "West Indian island group" .)

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