Darwin Harbour Cruise vessels – do not have the capabilities to have wheelchairs on board. Guests must possess reasonable level of mobility to board and disembark our vessel. Due to tidal effects on the port’s gangways and the vessel’s design, we are unable to accommodate individuals who require mobility aids such as wheelchairs and walkers. Those needing physical or mental support must be accompanied by a capable companion. Guests are permitted to bring walking sticks as necessary.
