Tusa Reef Tours (formerly Tusa Dive) is a Cairns-based day tour operator with over 35 years of experience taking visitors to the Outer Great Barrier Reef aboard a purpose-built catamaran. The company holds Advanced Ecotourism Operator accreditation and is part of the Entrada Travel Group, which also owns the Divers Den PADI 5-Star dive school in Cairns. Their signature trip is a half-day outer reef excursion (max 60 guests) departing from Cairns Marina, visiting one of several sites across Saxon and Hastings Reefs with up to two hours in the water. Alongside snorkelling, they run a PADI Discover Scuba Diving introductory dive for non-certified guests aged 12 and up, guided one-on-one by a PADI instructor to a maximum depth of 10 metres. All gear (mask, snorkel, fins, wetsuit, and for divers a full scuba set with BCD and computer console) is included in the trip price, along with an onboard photographer and optional pre-booked lunch. Tusa Reef Tours is a good option for travellers based in Cairns who want a well-organised, relatively short reef trip rather than a multi-day liveaboard, and for first-timers curious to try scuba diving before committing to a full certification course.
