Scawfell Island Sailing
Guide
Scawfell Island Sailing Guide. Scawfell Island sits east of the Cumberland Islands and north‑east of Mackay, forming the region’s premier offshore weather‑waiting anchorage. It is steep, rugged, and heavily reef‑fringed, with a single outstanding all‑weather anchorage, Refuge Bay on its north‑western side. The island’s eastern and southern faces are exposed to Coral Sea swell, with steep drop‑offs and narrow reef shelves. Scawfell is uninhabited, with no facilities, and is used almost exclusively by cruising yachts staging for offshore passages or waiting out strong trade winds.
The underwater profile around Scawfell is deeper and more abrupt than the inner Cumberland islands, with offshore depths of 30–50 m reducing to 14–20 m near the shoreline. Inside the anchoring zones, depths settle into 8–14 m over firm sand. Fringing reef is extensive and rises from 3–6 m into the reef flat. Refuge Bay provides the only reliable shelter in SE–E winds, while all other sides of the island are exposed and only workable in calm conditions.

Guide -Approaches
Scawfell Island lies offshore from the main Cumberland chain and is widely regarded as one of the best protected anchorages between the Whitsundays and the Percy Islands. Refuge Bay is the key feature—deep, enclosed, and well‑protected from the trade‑wind regime. Offshore depths remain consistently 30–50 m, reducing to 14–20 m near the shoreline. Inside the anchoring areas, depths sit in 8–14 m over firm sand. The eastern and southern sides are steep, reef‑bound, and unsuitable for anchoring.
Scawfel Island Refuge
Bay (Primary Anchorage – North‑West Side)
Refuge Bay is the main anchorage and one of the most secure in the entire central Queensland coast. Approaches are straightforward, with offshore depths of 30–40 m reducing to 16–20 m as you enter the bay. Inside, anchoring depths sit in 8–14 m over firm sand, with the central basin offering the cleanest holding. The seabed slopes gently toward the beach, and the anchorage remains mostly free of coral except near the headlands.
Refuge Bay provides excellent protection in SE–E winds, with the high ridges of Scawfell blocking both wind and swell. It remains comfortable even in strong trade‑wind conditions. It becomes exposed in N winds and develops a light roll in NW–W winds depending on swell direction. Swing room is generous, and the bay can accommodate multiple vessels. Dinghy access is straightforward at all but the lowest tides, with 1–1.5 m at the shoreline.
Scawfel IslandNorth‑East Pocket
(Fair‑Weather Only)
A small pocket on the north‑eastern side provides a secondary anchorage in calm conditions. Offshore depths of 34–46 m reduce to 18–22 m near the shoreline. Inside, anchoring depths sit in 10–14 m over sand with isolated coral. The fringing reef rises from 3–6 m, and coral heads lifting into 2–3 m are scattered across the northern margin. This pocket is workable only in light W–SW winds and becomes untenable in any SE–E wind. Dinghy landing is limited by reef shelves.
Scawfel Island Eastern
Side (No Anchorage)
The eastern side of Scawfell Island is fully exposed to Coral Sea swell and unsuitable for anchoring. Offshore depths of 40–50 m reduce to 20–26 m near the shoreline, but the seabed drops steeply and anchoring bands are extremely narrow. Fringing reef rises from 3–6 m, and coral heads lifting into 2–3 m are common along the eastern margin. This side is used only for transit.
Scawfel Island Southern
Side (Transit Only)
The southern side is steep, exposed, and not suitable for anchoring. Offshore depths of 36–48 m drop quickly into deeper water, and the fringing reef rises abruptly from 3–6 m. Swell wraps around the headlands in SE–E winds, and the shoreline offers no protection. This area is used only for transit between Refuge Bay and offshore routes.

Guide - Navigation Notes
Navigation around Scawfell Island is straightforward but requires attention to reef shelves and steep depth transitions.
- Depth transitions are abrupt, from 30–50 m offshore to 14–20 m near the shoreline.
- Fringing reef is extensive and rises from 3–6 m into the reef flat.
- Coral heads lifting into 2–3 m are common near the eastern and southern points.
- Refuge Bay has a wide, clear entry with predictable depth gradients.
- Tidal streams are moderate, with mild cross‑set near the northern approaches.
- Visibility is generally good, and reef edges are easy to identify in settled conditions.
- Low sun angles can obscure coral heads; late‑day arrivals require caution.
The safest entry line is a central approach into Refuge Bay, avoiding the reef shelves on the eastern and southern sides.

Guide - Weather
Scawfell Island’s western anchorage (Refuge Bay) is reliable in SE–E trade winds, with winds commonly 15–25 knots during the season. Refuge Bay remains comfortable even in strong trades, making it a preferred weather‑waiting anchorage for vessels staging for offshore passages. N winds render the bay exposed and uncomfortable, and NW–W winds can introduce a light roll. S–SW winds remain workable but may produce a gentle swell depending on direction. Tidal range is moderate, and streams set predictably around the island.

Guide - Summary
Scawfell Island provides one of the most dependable anchorages on the central Queensland coast, with clean sand bottoms, predictable depth profiles, and strong protection in SE–E winds. Refuge Bay is the primary anchorage and the only consistently usable option, offering deep, sheltered holding ideal for weather waiting. The eastern and southern sides are exposed and unsuitable for anchoring. Scawfell functions as a key offshore waypoint for yachts transiting between the Whitsundays, the Cumberland Islands, Mackay, and the southern GBR islands.
