What to expect
You'll board a purpose-built vessel in Cairns and cruise to a permanently anchored platform several kilometres offshore. The reef site is carefully chosen for its clarity and marine diversity. Most of your day alternates between water-based activities: snorkelling from the platform, viewing the reef through the glass-bottom boat's windows, and descending in the semi-submersible to observe fish and coral without diving. Between activities, marine biologists share practical knowledge about what you're seeing. Lunch is served buffet-style on the platform; bring cash if you want to purchase souvenirs or extras. The pace is relaxed and suits mixed abilities—you control how much time you spend in the water.
Good to know
Bring swimsuit, hat, towel, sunscreen, and sunglasses. The platform provides snorkelling equipment. If you're diving, you'll complete a medical questionnaire on board; asthma, epilepsy, and high blood pressure may disqualify you. Certified divers need certification cards. After diving, allow 12–24 hours before flying. Helicopter flights depend on weather and pilot discretion.
