'instance for remote uninhabited place' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'leave ireland' is the wordplay.
'leave' becomes 'desert' (desert can mean to leave or abandon).
'ireland' becomes 'island' (I can't explain this - if you can you should believe this answer much more).
'desert'+'island'='DESERTISLAND'

'for' is the link.
