The Glennie Group is a remote cluster of granite islands lying off the southern coast of Wilsons Promontory in Victoria's Gippsland region. Great Glennie Island, Dannevig Island, Citadel Island, and McHugh Island rise from the Bass Strait with windswept cliffs, rocky shorelines, and sheltered coves. These exposed waters are only accessible by private vessel in calm conditions, offering adventurous snorkelers the chance to explore pristine granite boulder gardens, kelp forests, and clear temperate waters. The isolation rewards those who make the journey with wild, untouched seascapes and stellar visibility on a good day.

High risk: Strong ocean currents
Bass Strait currents funnel between the islands, creating powerful and unpredictable flows that can quickly sweep swimmers out to sea.
Moderate risk: Swell and surge
Exposed to Southern Ocean and Bass Strait swells; large waves and surging water around rocky shorelines make entries and exits hazardous.
Moderate risk: Variable weather
Rapidly changing conditions with strong winds, fog, and rough seas can strand visitors; only attempt in settled weather windows.
Moderate risk: Remote location
No facilities, emergency services, or regular vessel traffic; self-sufficiency and safety equipment are essential.
Low risk: Cold water temperatures
Temperate Bass Strait waters range from 11-16°C year-round, posing hypothermia risk without adequate thermal protection.
