How to Do It Right
Booking Your Reef Escape
Target dry season departures from Cairns or Port Douglas for reliable weather. Book 4-6 weeks ahead in peak months to secure spots on high-rated operators like Reef Magic. Check sea conditions via Bureau of Meteorology the day before.
Arrive at ports 45 minutes early for check-in and safety briefings. Opt for small-group tours under 50 people to avoid crowds at prime snorkel spots. Follow coral-safe sunscreen rules and no-touch policies.
Practice breath-holding and fin kicks before arrival for efficient snorkeling. Rent semi-submersibles if seasick-prone. Explore independently via glass-bottom boats at islands like Green Island.
