Bluewater Marina sits at Trinity Park, roughly 15 kilometres north of Cairns, where Moore's Gully outlets to tidal water after draining the nearby Macalister Range.

The marina holds 108 berths and is cyclone-rated, with deep-water access to the Coral Sea and Great Barrier Reef reachable in about 20 minutes offshore.

Entry is via a narrow, mangrove-lined creek channel that can run shallow at low tide, making the approach demanding for visiting vessels.

That same winding creek geometry is what gives the marina its reputation as one of the most cyclone-secure facilities on the tropical Queensland coast.

Because the berths sit close to a freshwater creek influence, hull growth is reportedly reduced compared to fully saltwater locations.
