Misled unlimited bit of land (4)

I believe the answer is:

isle

'bit of land' is the definition.
(I've seen this before)

'misled unlimited' is the wordplay.
'unlimited' says the answer is hidden in the clue (the answer is currently being held or limited).
'ISLE' is hidden within 'misled'.

(Other definitions for isle that I've seen before include "Small landmass" , "inch, perhaps" , "Hawaii, perhaps" , "Isolated land" , "you can't walk away from" .)

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