The Oceanic 6 fake rescue in Sumba

The Oceanic 6 fake their rescue on the isle of Sumba to back up their cover story. They wash up in Sumba and are helped by the some locals, just as we saw in the photo during the press conference. They've gone to great lengths to support their cover story including wearing dirty, worn out clothing and using paddles made out of salvaged materials.

Penny, Desmond, Frank and the rest of Penny's crew helped with their fake story, so you can bet this will come into play in season 5.
