Mourilyan Harbour boat ramp sits on Walter Creek within the broader Moresby River system, about 9 kilometres south of Innisfail in Queensland's Cassowary Coast region.

The facility features a two-lane concrete ramp and is a popular departure point for recreational fishing, with the surrounding waterway offering mangrove-lined channels, creeks, sandbars, and shale-bottom areas.

The ramp's narrow entrance faces into prevailing winds, which can funnel through the opening and create choppy conditions in bad weather; tidal movement is also accentuated here.

Water for boat washdown is available on site, and parking can be tight during peak periods, with priority given to vehicles towing trailers.
