Long Island offers calm, shallow water diving and snorkelling in Queensland, making it a genuinely welcoming site for beginners. Depths stay between 1 and 5 metres, so you spend most of your time in easy reach of the surface. Visibility is variable, so conditions can change between visits. Currents also vary, so it pays to check conditions before you enter. The marine life is the real drawcard here, with green sea turtles, hawksbill turtles, and loggerhead turtles regularly encountered, alongside clownfish, giant trevally, and Napoleon wrasse. Be aware of jellyfish and give all marine life respectful space.

Go early in the morning when surface conditions tend to be calmer and turtle activity is often at its most reliable. Equipment hire is available on site, so you do not need to travel with your own gear.
Access to Long Island is by boat only. Water taxis and ferry services, such as Island Transfers and Mars Charters, operate from Shute Harbour (near Airlie Beach) and Hamilton Island, taking visitors to Palm Bay.
A key hazard is marine stingers (jellyfish), including the dangerous Box and Irukandji jellyfish. The stinger season runs from October to May, and wearing a full-body stinger suit is highly recommended during these months.
