Lady Musgrave Island (Capricornia Cays)

Moderate risk: Outgoing tide current

Strong currents can develop in the lagoon channels during outgoing tides, especially near the reef wall openings.

Moderate risk: Marine stingers

Box jellyfish and Irukandji may be present in warmer months (November to May). Stinger suits are recommended.

Moderate risk: Strong drift current

The Camp Grounds is a drift dive/snorkel site where the current can be strong and unpredictable, sweeping snorkellers along the reef wall.

Moderate risk: Depth exposure

Depths reach up to 18m with potential to drift deeper; not suitable for inexperienced snorkellers or weak swimmers.

Moderate risk: Marine stingers (box jellyfish)

Box jellyfish and Irukandji may be present in warmer months. Wear a stinger suit.

Moderate risk: Tidal currents

Strong currents can sweep across the outer reef bommies, especially during tidal changes. Snorkellers should be strong swimmers and stay close to the boat or guide.

Moderate risk: Marine stingers (jellyfish)

Marine stingers (including box jellyfish and Irukandji) are present in these waters during the warmer months.

Low risk: Boat crossing seasickness risk

The 80-minute boat crossing from Town of 1770 crosses open Coral Sea swell that can be moderate to rough; seasickness is common.

Low risk: Turtle nesting season

Green turtles nest November–March; visitors must not approach or disturb nesting turtles or seabirds on this protected national park cay.

Low risk: Stinger season

Box jellyfish and other marine stingers may be present in warmer months; stinger suits recommended November–May.

Low risk: Sun exposure

Intense tropical sun with reflection off the lagoon's turquoise water. Reef-safe sunscreen, rashie or wetsuit top essential.

Low risk: Sharp coral

Shallow reef areas have sharp coral formations that can cause cuts; avoid touching and wear reef shoes.

Low risk: Open ocean crossing

The 90-minute to 2.5-hour boat crossing crosses open ocean with possible 1–1.5 m swells and 10–15 knot winds. Seasickness is common; preventative medication is recommended.

Low risk: Tidal currents at lagoon entrance

The lagoon entrance is narrow, and tidal currents can be strong during ebb and flood flows. Snorkellers should stay within the protected lagoon.

Low risk: Strong Midday Sun

Limited shade on the pontoon and lagoon; sunburn and heat exhaustion risk without reef-safe sunscreen and a hat.

Low risk: Coral Cuts

Sharp coral heads in shallow areas of the lagoon can cause cuts and scrapes if swimmers stand or bump into them.

Low risk: Boat traffic

Access is by boat only and the site lies on the outer reef wall, requiring careful surface awareness and boat pickup coordination.

Low risk: Strong tidal currents at reef passages

Tidal flow through the lagoon entrance and around the reef edge can be strong. Snorkel with a guided group.

Low risk: Coral cuts and scrapes

Sharp coral formations close to the surface. Avoid touching coral and wear protective footwear.

Low risk: Boat transfer seasickness

Open ocean conditions during the 2+ hour boat transfer can be rough, causing seasickness for susceptible passengers.

Low risk: Exposed reef swell

The site is an exposed outer reef feature with no land shelter. Swell and wind can pick up suddenly, making conditions challenging.

Low risk: Boat traffic in lagoon channel

Vessels enter and exit the lagoon channel; snorkelers must stay within marked swimming areas away from boat traffic.

Low risk: Seasickness on boat transfer

The open-ocean crossing from the mainland can be rough; sea sickness is common on the 90-minute to 2.5-hour boat transfer.

Low risk: Seasickness on boat transit

Open ocean crossing of ~2 hours can cause seasickness on the boat ride out. Prevailing winds and swell affect conditions.
