Outer Newry Island Sailing Guide. Outer Newry Island sits immediately north‑west of Newry Island and forms the second major anchorage of the Newry group. It is low, rocky, and heavily reef‑fringed, with a single workable anchorage on its western side and several narrow fair‑weather pockets. The island is used primarily for short‑stay shelter, day visits, and staging for vessels moving between Mackay, the Cumberland Islands, and the inshore Newry cluster. There are no facilities, and all anchorages are used solely for overnight shelter.
The underwater profile around Outer Newry Island is shallow and compact, with offshore depths of 14–20 m reducing to 8–12 m near the shoreline. Inside the anchoring zone, depths settle into 4–8 m over sand with isolated coral. Fringing reef rises from 2–4 m into the reef flat, restricting swing room and narrowing anchoring bands. The western side provides the only reliable shelter in SE–E winds, while the eastern side is exposed and only workable in calm conditions.
Outer Newry Island lies close inshore north of Mackay and forms a paired anchorage system with Newry Island. Its western pocket provides a small but dependable anchorage in SE–E winds, with clean sand patches and predictable depth gradients. Offshore depths remain consistently 14–20 m, reducing to 8–12 m near the shoreline. Inside the anchoring area, depths sit in 4–8 m over sand. The eastern side is exposed to swell and unsuitable except in light conditions.
The western pocket of Outer Newry Island is the main anchorage and the most reliable on the island. Approaches are simple, with offshore depths of 14–20 m reducing to 8–12 m as you close the shoreline. Inside, anchoring depths sit in 4–8 m over firm sand, with the central basin offering the cleanest holding. The seabed slopes gently toward the island, and the anchorage remains mostly free of coral except near the northern and southern points.
The pocket provides workable protection in SE–E winds, with minimal swell intrusion. It becomes exposed in N winds and develops a light roll in SW winds depending on swell direction. Swing room is limited by fringing reef rising from 2–4 m on both points, making conservative scope essential. Dinghy access is possible at mid‑to‑high tide, with 1–1.5 m at the shoreline.
A small shelf on the north‑western side provides a secondary anchorage in moderate conditions. Offshore depths of 14–18 m reduce to 8–10 m near the shoreline. Inside, anchoring depths sit in 4–6 m over sand with isolated coral. The fringing reef rises from 2–4 m, and coral heads lifting into 1–2 m are scattered across the northern margin.
This anchorage is workable in SE–S winds but becomes exposed in W–N winds. Swing room is limited, and the anchorage is best suited to smaller vessels. Dinghy landing is possible at mid‑tide, though reef shelves restrict access at lower water.
A narrow pocket on the south‑western side provides a small fair‑weather anchorage. Offshore depths of 16–20 m reduce to 8–10 m near the shoreline. Inside, anchoring depths sit in 3–5 m over sand with isolated coral. The fringing reef rises from 2–4 m, and coral heads lifting into 1–2 m are common.
This anchorage is workable only in light SE–S winds and becomes untenable in W–N winds. Dinghy landing is limited by reef shelves and tidal height.
The eastern side of Outer Newry Island is exposed to swell and unsuitable for anchoring. Offshore depths of 16–22 m reduce to 8–12 m near the reef edge, but the seabed drops steeply and anchoring bands are extremely narrow. Fringing reef rises from 2–4 m, and coral heads lifting into 1–2 m are common along the eastern margin. This side is used only for transit.
Navigation around Outer Newry Island is straightforward but requires attention to shallow reef shelves and limited swing room.
Depth and Seabed
Operational considerations
Outer Newry Island is influenced by the SE trade‑wind regime, with winds commonly 15–22 knots during the season.
The western pocket remains comfortable in SE–E winds, while all anchorages become exposed in N winds.

Outer Newry Island provides a small but workable anchorage on its western side, with clean sand bottoms, predictable depth profiles, and partial protection in SE–E winds. The western pocket is the primary anchorage and the only consistently usable option, while the north‑west shelf and south‑west pocket are strictly fair‑weather. The eastern side is exposed and unsuitable for anchoring. Outer Newry Island functions as a practical short‑stay stop for yachts transiting between Mackay, the Newry Islands, and the Cumberland Islands. Outer Newry Island Sailing Guide is here to help you.
