Frequently Asked Questions for Green Island and Great Barrier Reef Adventure

  • How do I check-in before departure?
    Please check-in at the Great Adventures counters inside the Reef Fleet Terminal (1 Spence Street in Cairns) 1 hour before your departure time.
  • Will I get seasick?
    Hopefully not. The large, stable fast catamarans provide very good sea keeping even in rougher ocean conditions. Where there is motion, whether a car, bus, plane or boat, some people will suffer from motion sickness. Motion sickness tablets are available onboard for purchase. There are also ginger tablets as a natural alternative motion sickness medication on a complimentary basis. To be effective, motion sickness medications should be taken immediately on boarding. If you are concerned about potential motion sickness, being closer to the coast, Green Island is a shorter 45 minute journey and is more protected than a cruise to the Outer Reef.
  • Do you supply life jackets?
    Life jackets are onboard for emergency use only. However, flotation/buoyancy vests are available for use whilst swimming or snorkelling. At Green Island, these can be hired from the Dive Shop. For passengers continuing on to the Outer Reef, please help yourself to these from the front of the platform with the rest of your snorkelling equipment.
  • What is the temperature of the water?
    The warm waters of Tropical North Queensland range in temperature from 22-29 Celsius (75-85 Fahrenheit) and make for year round comfort for water activities.
  • What time does the boat depart Cairns and return?
    For the “Green Island and Great Barrier Reef Adventure”, your vessel departs Cairns at 8.30am, departs the island at 11.30am, and returns to Cairns at approximately 5.20pm.
  • If we book a certain return time for a Green Island cruise, can we change to an earlier or later departure once we are over on the Island?
    Yes, if there is availability the crew at the Information Counter on Green Island can amend your return times. If it is fully booked however, you will have to return on your originally scheduled departure time.
  • How long do we spend at the Outer Reef and how long does it take to get there?
    You will spend approximately 3 hours at the Outer Reef Platform. Travelling time from Green Island to the Outer Reef is approximately 50 minutes.
  • Is Green Island still part of the Great Barrier Reef?
    Yes, Green Island is situated in the Inner part of the Great Barrier Reef.
  • Do you have prescription masks available?
    Standard masks magnify objects underwater by about 25%. We do have prescription masks up to -8.0 available. If you need a prescription mask, please advise when reconfirming your booking locally as there is a limited supply, especially in the higher prescription strengths.

    Yes, the daily buffet lunch at the Outer Reef provides food options for vegetarians. All menu options are labelled with ingredients lists.
