Hunter Island
Sailing Guide
Hunter Island Sailing Guide. Hunter Island is the northern gateway to the Duke Islands, sitting directly on the natural southbound track from the Percy group. It is the first landfall most skippers use when dropping down from Middle or South Percy, and it sets the tone for the entire chain: steep, rugged, reef‑fringed, and offering its only dependable shelter on the western side. The island is uninhabited, exposed on all but its lee shore, and used almost entirely for overnight staging rather than extended stays.
The underwater profile around Hunter is typical of the Dukes. Offshore depths sit broadly in the 26–40 m range, tightening to 12–18 m near the shoreline, and flattening into 6–12 m over firm sand inside the anchoring zone. Fringing reef rises from 3–6 m, mostly confined to the headlands, and isolated coral heads lifting into 2–3 m appear only at the margins. The island sits in open water, and tidal streams run cleanly along its flanks, with a mild but noticeable set in the northern and southern approaches.

Sailing Guide
Hunter Island is the most accessible anchorage when arriving from the Percy Islands and is often the first stop when shaping a course south. Its western bay is simple to enter, deep enough to feel secure, and protected enough to give a comfortable night in normal trade‑wind conditions. The island’s height throws a modest but effective lee, and the holding is consistently firm over sand. Hunter is not as sheltered as Marble or as dramatic as Hexham, but it is reliable, predictable, and perfectly placed for a one‑night stop.
The eastern side of the island is steep, reef‑bound, and fully exposed to Coral Sea swell. It offers no anchoring opportunities and is used only for transit. Approaches from the west are clean and confidence‑building, with no hidden hazards and a smooth depth transition from offshore water into the anchoring zone.
West Bay (Primary
Anchorage)
The western anchorage is the operational centre of Hunter Island. Approaches from the west are straightforward: offshore depths of 26–34 m ease into 12–16 m as you close the shoreline, then settle into 6–12 m over firm sand inside the anchoring area. The seabed is mostly clean, with coral confined to the northern and southern points. The bay is broad enough to accommodate several vessels without crowding, and the swing room is generous.
Shelter in SE–E winds is good. The island’s height blocks the worst of the breeze and swell, and the anchorage remains comfortable in typical trade‑wind conditions. A light roll may develop in SW–W winds depending on swell direction, but it rarely becomes uncomfortable. The anchorage is exposed to N winds, and conditions deteriorate quickly if the breeze shifts north of east.
Dinghy access is straightforward at mid‑to‑high tide, with 1–1.5 m at the shoreline. The beach is steep enough to land cleanly but still requires attention in swell.
North‑West Margin
(Fair‑Weather Only)
A small indentation on the north‑western side can be used in calm conditions, though it is not a primary anchorage. Depths are similar to the main bay, but coral heads are more common and the swing circle is tighter. This pocket is workable only in light W–SW winds. Any SE–E breeze sends swell straight into it, and the anchorage becomes uncomfortable quickly. It is best treated as a daytime or fair‑weather option rather than an overnight stop.
Eastern Side
(Transit Only)
The eastern face of Hunter Island is steep, exposed, and reef‑fringed. Offshore depths of 30–40 m drop abruptly to 16–20 m near the reef edge, and the fringing reef rises from 3–6 m with isolated coral heads in 2–3 m. Swell wraps around the headlands in all but the calmest conditions. There is no anchoring room, and the area is used solely for transit.

Sailing Guide - Navigation notes
Navigation around Hunter Island is simple in settled weather. The western approaches are clean, with a smooth depth gradient and a predominantly sandy bottom. Reef shelves are easy to read in good light, though low sun angles can obscure coral heads in the fair‑weather pockets. The eastern side should be given a wide berth in fresh trades, as swell breaks on the reef edge and the depth transition is abrupt.
Tidal streams are moderate and predictable, with a mild set along the northern and southern approaches. They rarely complicate anchoring but should be factored into close‑quarters manoeuvring near the reef.
Hunter Island
Sailing Guide - Weather
Hunter Island sits firmly in the SE trade‑wind regime, with typical seasonal winds in the 15–25 knot range. The western anchorage remains comfortable in these conditions and is a reliable overnight stop when moving south from the Percy Islands. The anchorage becomes progressively more exposed as the wind moves into the north, and N–NE winds can make the bay uncomfortable or untenable.
Swell intrusion is minimal on the western side in normal trades but immediate on the eastern face. Tidal range is moderate, and streams in the inter‑island channels are predictable and rarely hazardous.

Sailing Guide - Fishing
Fishing around Hunter Island is shaped by the steep fringing reef and the strong tidal flow that wraps the island’s eastern and southern faces, creating a compact but energetic fishery for yachts. The broken reef shelves hold coral trout, sweetlip, tuskfish, and cod in settled weather, while the deeper water off the points regularly sees Spanish mackerel, queenfish, trevally, and longtail tuna pushing bait along the contour on the turn of the tide. The western side offers a calmer lee where bait often stacks in the sand patches, giving dinghy crews a reliable drift without getting too close to the reef. As with the broader central Queensland reef belt, skippers favour smaller reef fish and pelagics due to ciguatera risk in larger specimens. Overall, Hunter Island rewards timing the tide, working the pressure edges, and staying mobile rather than anchoring near structure.
Hunter Island
Sailing Guide - Summary
Hunter Island is the northern entry point to the Duke Islands and a reliable, straightforward anchorage for vessels transiting between the Percy Islands and Shoalwater Bay. Its western bay offers predictable holding, clean approaches, and solid protection in SE–E winds. The north‑west pocket is strictly fair‑weather, and the eastern side is transit‑only. Hunter is not the most sheltered island in the chain, but it is the most convenient and often the most useful when shaping a southbound passage.
