Seawalker Green Island

What Seawalker Green Island does

Seawalker Green Island operates a single-location underwater helmet diving experience on Green Island, a 6,000-year-old coral cay approximately 27km offshore from Cairns in Tropical North Queensland, Australia. The company was founded in 2003 and is wholly owned within the Quicksilver Group, a diversified reef tourism conglomerate that also operates the Great Adventures fast catamaran ferry service. The core product is a 60-minute seafloor walk at approximately 5 metres depth using a proprietary Seawalker helmet that is lowered onto the participant's shoulders; the system requires no swimming ability, no prior diving certification, and no equipment operation by the guest, and participants do not get their hair wet. Wetsuits and dive boots are provided complimentary, and a professional underwater photographer offers photos for purchase as a secondary revenue stream.

The target customer is the domestic and international tourist visiting Tropical North Queensland, with explicit positioning for non-swimmers, families (minimum age 12), and adventure seekers who want a Great Barrier Reef experience without scuba certification. The company maintains dedicated English and Japanese (シーウォーカーグリーンアイランド) websites to serve inbound Japanese visitors. Distribution is structured around three channels: pre-booked online via the Respax platform bundled with the Great Adventures Green Island Eco Adventure (AUD $289 adult / AUD $236 child), standalone on-island or onboard booking at AUD $205 per person subject to availability, and on-site sales at the Green Island Dive Shop. A fuel surcharge of AUD $4 per adult and AUD $2 per child applies from 1 April 2026, with prices valid to 31 March 2027.

The business model is high-touch experiential tourism with structural revenue concentration tied to ferry capacity, since all customers must arrive via the four daily Great Adventures ferry slots. The company holds Advanced Ecotourism Certification from Ecotourism Australia and a Climate Action Business certification, and has received the Queensland Tourism Awards 'Adventure Tourism' Award. There are no patents, no proprietary digital platform, no AI capabilities, and the operation is staffed at 11–50 employees; the offering has remained structurally consistent for over two decades with no disclosed M&A, funding, or geographic-expansion activity.
