Percy Islands Sailing Guide
Percy Islands Sailing Guide. The Percy Islands sit south of the Cumberland Islands and north of Shoalwater Bay, forming one of the most iconic cruising regions on the central Queensland coast. The group consists of North Percy, Middle Percy, South Percy, and several smaller outliers including Pine Peak, Pine Islet (Percy), South Island, and Raspberry Creek Islet. The islands are rugged, steep, and heavily reef‑fringed, with deep, reliable anchorages on their western sides and exposed, fair‑weather‑only options on their eastern faces. Middle Percy is the cultural centre of the group, famous for West Bay and the A‑frame hut.
The underwater profile across the Percy Islands is deeper and more abrupt than the inshore groups, with offshore depths of 24–50 m reducing to 12–20 m near the shoreline. Inside the anchoring zones, depths settle into 6–14 m over firm sand. Fringing reef rises from 3–6 m into the reef flat, restricting swing room near headlands. The western sides of all islands provide the most dependable shelter in SE–E trade winds, while the eastern sides are exposed to Coral Sea swell and only workable in calm conditions.
Percy Islands
Sailing Guide – The Group
The Percy Islands include the following islands:
- North Percy Island.
- Middle Percy Island
- South Percy Island
- Pine Peak
- Pine Islet (Percy)
- South Island
- Minor rocks and islets
The group forms a single operational cruising region due to its shared depth profiles, anchoring characteristics, and position on the offshore route between the Whitsundays and the Capricorn Coast.

Summaries
Middle Percy Island. Middle Percy is the heart of the group and home to the famous West Bay anchorage. Offshore depths of 24–40 m reduce to 12–18 m, with anchoring depths of 6–12 m over firm sand. West Bay is reliable in SE–E winds, with a wide sand basin and good holding. The eastern side is steep, reef‑bound, and fair‑weather only. Middle Percy is the most visited island in the group and the primary stop for vessels transiting the region.
North Percy Island. North Percy is rugged and steep, with a large, deep anchorage on its western side. Offshore depths of 30–50 m reduce to 14–20 m, with anchoring depths of 8–14 m over sand. The bay remains comfortable in SE–E winds and is often used as a quieter alternative to Middle Percy. The eastern side is exposed and unsuitable for anchoring.
South Percy Island. South Percy is the most exposed of the three main islands, with a workable anchorage on its western side and several narrow fair‑weather pockets. Offshore depths of 26–40 m reduce to 12–18 m, with anchoring depths of 6–10 m over sand. The eastern and southern sides are steep and reef‑bound. South Percy is used mainly as a staging point for vessels heading south toward Shoalwater Bay.
Pine Peak & Pine Islet (Percy). These small outliers provide no reliable anchorage but serve as visual references when navigating between the main islands. Offshore depths of 30–46 m reduce to 14–20 m near the reef edge, but anchoring bands are narrow and coral‑bound.

Characteristics
Across the Percy Islands, anchoring conditions are consistent:
- Offshore depths: 24–50 m
- Near‑shore depths: 12–20 m
- Anchoring depths: 6–14 m over firm sand
- Fringing reef: 3–6 m, confined to headlands
- Coral heads: 2–3 m, occasional in fair‑weather pockets
- Bottom type: Predominantly sand with isolated coral
The western sides of all islands provide the most reliable shelter in SE–E winds. Eastern sides are exposed and only workable in light W–SW winds.

Anchorages
Middle Percy – West Bay. The signature anchorage of the region. Approaches are simple, with offshore depths of 24–34 m reducing to 12–16 m. Inside, anchoring depths sit in 6–12 m over firm sand. The bay provides excellent protection in SE–E winds and remains comfortable in fresh trades. Swell intrusion is minimal. Dinghy access is straightforward at all tides.
North Percy – West Bay. A deep, reliable anchorage with offshore depths of 30–50 m reducing to 14–20 m. Inside, anchoring depths sit in 8–14 m over sand. The bay is well protected in SE–E winds and offers generous swing room. Coral is confined to the headlands.
South Percy – West Side. A smaller anchorage with offshore depths of 26–40 m reducing to 12–18 m. Inside, anchoring depths sit in 6–10 m over sand. The bay is workable in SE–S winds but becomes exposed in N winds.
Percy Islands Sailing Guide - Navigation
Notes
Navigation throughout the Percy Islands is straightforward but requires attention to reef shelves and steep depth transitions.
Depths and Seabed
- Offshore depths: 24–50 m
- Near‑shore depths: 12–20 m
- Anchoring depths: 6–14 m
- Fringing reef: 3–6 m, extensive around headlands
- Coral heads: 2–3 m, common in fair‑weather pockets
Percy Islands Sailing Guide - Operational considerations
- Tidal streams are moderate, with noticeable set between the islands.
- Reef edges are easy to identify in settled conditions.
- Low sun angles can obscure coral heads; late‑day arrivals require caution.
- The safest entry lines are central approaches into the western anchorages.
The approaches from both the Whitsundays and Shoalwater Bay are deep and unobstructed.
Percy Islands Sailing Guide - Weather
The Percy Islands are strongly influenced by the SE trade‑wind regime, with winds commonly 15–25 knots during the season.
- Best shelter: West Bay (Middle Percy), North Percy West
- Moderate shelter: South Percy West
- Fair‑weather only: Eastern sides of all islands
- Exposed: All anchorages in N winds
- Swell: Minimal on western sides; immediate intrusion on eastern sides
- Tidal range: Moderate, with predictable streams in inter‑island channels
Middle Percy’s West Bay remains comfortable even in strong trades.
Percy Islands Sailing Guide - Fishing
Fishing around the Percy Islands is classic offshore reef country, shaped by clear water, strong tidal flow, and the steep contours that fall away from Middle, North, and South Percy into deep blue almost immediately. The islands hold a reliable mix of coral trout, sweetlip, tuskfish, and cod along the bommies and ledges, with Spanish mackerel, queenfish, trevally, and tuna working the pressure lines and bait schools offshore.
The best fishing comes on the tide changes, when the current eases enough for reef species to move up onto the structure and for pelagics to push bait toward the islands. The western sides of Middle and North Percy often hold bait in the lee of the trades, while the eastern faces produce more pelagics when conditions settle. Most skippers fish from the dinghy to stay mobile and avoid anchoring too close to the reef, and the deeper channels between the islands can fire when the water is clean.
Ciguatera risk exists, as it does across the central Queensland reef belt, and large coral trout and Spanish mackerel should be treated with caution. Overall, the Percy Islands offer a productive, structure‑driven offshore fishery with a dependable mix of reef species and pelagics, best worked around the tide and best approached with the same respect you give the reefs themselves.
