its over 2-2.5km once you factor in the last bit past the island out to the actual break.
have paddled it on long board, to surf out there on small days, plus sup as well when not worth a shorty. it's a decent roll of the arms. got to be able to swim 2km minimum in case of full loss of gear (and go with at least 1 other buddy recommended)
confident self rescue skill is handy to have, but still problematic if it swings offshore as per advice from qube.
it's bumpy if only wind waves. best is swell, and get the cleaner later waves in set.
probably better to just avoid it...
