What are the exact coordinates to the islands of the TV show lost?

Well, if we don’t know for sure, how could we give you the exact coordinates?

Lost is filmed in Hawaii.
I suppose that is technically northeast of Australia.

Since they aren’t real islands, you can give them any coordinates you want.

Otherwise, just about everything has been filmed on the island of Oahu, except for a few bits in London because of cast scheduling. The coordinates for Honolulu, on the island of Oahu, are:
Latitude: 21° 19’ North
Longitude: 157° 50’ West
