The OceanQuest is a live-aboard dive boat fashioned from an old shrimping vessel. The Oceanquest only comes into Cairns twice a year to re-fuel or if there is a typhoon. The OceanQuest like the ReefQuest are both operated by Deep Sea Divers Den in Cairns. The folks at Deep Sea Divers Den have served Cairns for over 25 years, they are the top PADI out-fit for the serious scuba-diver.
