Conditions & Currents
Moderate currents can run here, so plan drift entries and stay close to the group. Dive profiles here run between roughly 10 and 30 metres, so plan your gas and no-decompression limits around the deeper part of the site. It is usually briefed as a dive for beginner divers. The site is reached by liveaboard, so entries are run from the tender or straight off the back deck. Tide, wind and season all shift the picture from day to day, so the crew's briefing on the boat always overrides any general description.
Why dive Josie’s Reef from a liveaboard?
Josie’s Reef is one of Papua New Guinea's signature dive sites. A liveaboard sleeps you on the water and puts you in the water for three to four guided dives per day, including dawn and night dives that day-boat operators rarely offer. You skip the daily commute back to port and reach quieter, less-crowded sites in the same region on a single trip.
