Keppel Bay Islands National Park (various sites)

High risk: Remote location - no facilities

This is a remote island with no facilities, no drinking water, and no mobile reception. Self-sufficiency is essential.

Moderate risk: Tidal currents

Strong tidal currents can flow through Keppel Bay, especially around island passages. Snorkellers should be aware of changing tides.

Moderate risk: Extreme sun exposure

Sun exposure is intense on the island with no shade facilities. Bring plenty of water, sun protection, and a hat.

Moderate risk: Marine stingers

Marine stingers (box jellyfish and Irukandji) are present in Keppel Bay waters during the warmer months. Stinger season runs October through May.

Moderate risk: Marine stingers (box jellyfish)

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

Moderate risk: Strong tidal currents

Tidal currents can run strongly between islands and around headlands, especially at Halfway Island. Always check tides before entering.

Moderate risk: Isolation and remote access

Accessible only by boat. No lifeguards, limited facilities on most islands. Never snorkel alone.

Moderate risk: Remote island access

Many snorkelling sites are on uninhabited islands with no facilities, emergency services, or fresh water. Self-sufficiency is essential.

Low risk: Marine life hazards (coral/reef fish)

Sharp coral cuts, stonefish, and reef fish stings are possible. Wear reef shoes and avoid touching coral.

Low risk: Boat traffic

Popular anchorage areas and ferry routes mean boat traffic in channels and near beaches. Snorkellers should stay visible.

Low risk: Strong tidal currents through channels

Tidal flows between islands can create unexpected currents, particularly around headlands like Olive Point.

Low risk: Remote location

No on-site medical facilities; evacuation from the islands takes time. Always snorkel with a buddy.

Low risk: Sharp coral and rocky reef edges

Fringing reefs have sharp coral formations. Wear reef shoes or fins and avoid touching coral to prevent cuts and protect the reef.

Low risk: Limited shade and sun exposure

Strong subtropical sun with limited shade on many beaches. Bring sun protection, water, and a hat.

Low risk: Sharp coral / rocks at low tide

Sharp coral and rocky outcrops at low tide, especially at Butterfish Bay and Passage Rocks.
