I had the pleasure of visiting Cairns, courtesy of the Super Yacht Group, Great Barrier Reef in May 2016. Cairns has excellent facility for superyachts. Marlin Marina, steps away from CBD and 10 minutes from the airport, has accommodated various yachts above 100m. For repair facilities, there are a few yards in Cairns including BSE Slipway, Norship Marine and skilled local tradesmen that could handle the demand of superyachts. With her proximity to South East Asia, Cairns is the gateway to Great Barrier Reef and an ideal stop for yachts heading to and from South Pacific.
I would not hesitate to recommend my clients to visit Cairns.
