Busselton Jetty

Moderate risk: Depth — cannot touch bottom

Water depth along the jetty snorkel trail ranges from 7–9 metres, meaning you cannot stand or touch the seabed. Snorkelers must be confident swimmers.

Low risk: Jetty traffic

Fishing lines, hooks, and boat traffic near the jetty structure require caution. Snorkelers should stay clear of fishing areas.

Low risk: Strong currents at jetty end

Occasional currents can build around the far end of the jetty, particularly on outgoing tides.

Low risk: Cold water temperature

Geographe Bay water temperatures can be cool year-round (15-22°C), making a wetsuit advisable for comfort and safety.

Low risk: Long swim distance

The snorkel trail runs near the 1.8 km jetty end. Snorkelers should be confident swimmers or join a boat tour to avoid fatigue.

Low risk: Boat traffic near jetty

Boats and the jetty train operate along the structure. Snorkelers must stay within the designated dive/snorkel zone and be aware of vessel movements.

Low risk: Stingrays and octopus

Stingrays resting on the sandy bottom and octopus hiding in crevices may be startled if approached too closely. Observe from a respectful distance.

Low risk: Comb jellyfish blooms

Seasonal blooms of harmless comb jellyfish (ctenophores) can occur, particularly in warmer months. While not dangerous, they can be encountered in large numbers.

Low risk: Strong afternoon sea breezes

Afternoon sea breezes can chop up the water and reduce visibility. Best to snorkel in the morning or on low-wind days.

Low risk: Cold water temperatures

Water temps range 18–23°C; extended immersion without a wetsuit can lead to cold exposure.

Low risk: Underwater Observatory exclusion zone

A 20 m exclusion zone surrounds the underwater observatory; swimming too close is prohibited and carries safety risks.

Low risk: Jetty traffic & structures

The jetty piles and underwater sculpture trail have submerged obstacles. Boats and jetty traffic operate in the area — stay aware and avoid swimming near vessels.

Low risk: Depth at jetty end

Water depth at the far end of the jetty reaches 7-9 metres with no standing bottom. Confident swimming ability is recommended for independent snorkellers.

Low risk: Stinger season (summer)

Marine stingers (box jellyfish) are occasionally present in warmer months from November to February. Stinger suits recommended.

Low risk: Limited shore entry path

Snorkelling the jetty requires entry from the beach or via guided tours. Access to the jetty end involves a 1.8 km walk/swim; plan accordingly.

Low risk: Train and pedestrian traffic

The jetty is very popular with walkers and trains — stay alert and keep clear of the train tracks when entering or exiting the water near the platform.

Low risk: Tidal currents around piles

Occasional strong currents can develop around the jetty piles, especially on outgoing tides, which may push swimmers away from the piles.

Low risk: Seasonal jellyfish

Stinging jellyfish may be present in Geographe Bay during summer months (December to February).

Low risk: Barnacle-encrusted piles

The jetty piles and submerged structure are covered in barnacles and encrusting organisms — cuts and scrapes can occur if not careful.
