Swan Wreck (HMAS Swan)

High risk: Depth

The wreck rests at 35m with superstructure shallower but still deep; strong freediving or scuba experience required for snorkelers.

Moderate risk: Strong ocean currents

Ocean currents can be strong around the wreck site, particularly at depth and tidal changes.

Moderate risk: Depth variation

Wreck rises from 32m to 8m — snorkellers should stay near the shallower sections (crows nest at ~8m) and avoid free-diving deep interior sections.

Moderate risk: Strong Swells and Currents

Exposed offshore location at Eagle Bay can experience strong swells, wind chop, and currents, especially in summer sea breezes.

Low risk: Boat traffic

The site is accessed by boat and shared with dive vessels; surface vigilance required.

Low risk: Cold water temperatures

Water temperatures in southwestern Australia can drop significantly, especially in winter months.

Low risk: Variable visibility

Visibility can vary greatly depending on swell and weather conditions, sometimes reducing to a few metres.

Low risk: Strong currents

Ocean currents can be unpredictable off Eagle Bay; snorkellers should check conditions with operators before entering.

Low risk: Cold Water

Water temperatures can drop to 16-18°C in winter, requiring wetsuit protection for thermal comfort and safety.

Low risk: Limited Visibility

Visibility can vary from 5–20m depending on swell, wind, and recent rainfall; plankton blooms in summer also reduce clarity.
