Stretching 37 km from Brunswick River to Lennox Head, Cape Byron Marine Park encompasses 220 km² of protected coastal waters where the warm East Australian Current meets cooler southern flows. This unique convergence creates a biodiversity hotspot with 10 of the 15 Tweed-Moreton bioregion ecosystems represented, including rocky reefs, sandy beaches, estuaries, and the iconic submerged pinnacles of Nguthungulli (Julian Rocks). Snorkellers can explore coral communities, ancient rock formations, and crystal-clear waters right off Byron Bay's famous coastline.

Logged by the community, confirmed by mods
Moderate risk: East Australian Current (EAC)
Strong warm-water current can create powerful sweeps and unexpected drift conditions, especially around Julian Rocks and headlands.
Moderate risk: Rip Currents at Unpatrolled Beaches
Many beaches within the marine park (Tallow, Kings, Brays, Whites) are unpatrolled with frequent rips that can catch swimmers off guard.
Moderate risk: Strong Ocean Currents
The convergence of warm northern and cool southern currents around Julian Rocks can create unpredictable and strong drift conditions.
Low risk: Boat Traffic
Active boating, diving, fishing and tour vessels operate throughout the park; snorkellers near Julian Rocks must be visible and stay with tour groups.
Low risk: Variable Water Visibility
Visibility fluctuates with seasonal swells, rainfall runoff from creeks, and wind conditions; best between late spring and early autumn (Nov–Apr).
Low risk: Marine Stingers
Bluebottles and box jellyfish can appear in warmer months; wear a stinger suit or rash vest during summer.
