LIFESAVING
SEA SENSE

Curriculum
Here's an overview of the dangers you'll learn to master over the next 3 months...
Rip Currents
You will learn how rip currents form out of seemingly calm channels, how to recognise them before getting in, and the precise escape route that turns a dangerous pull into a safe recovery.
Sharks
You will explore how to distinguish different types of shark, why most encounters are avoidable, and how to surf, swim and snorkel in shark-prone waters with calm decision-making instead of fear.
Islands
You will understand why small offshore islands become dangerous when the tide drops, how they strand people without warning, and how to read the signs that tell you when to turn back.
Cross-shore
You will learn how cross-shore winds move you sideways along the coastline, why swimmers and paddleboarders drift without noticing, and the navigation trick that keeps you aligned.
Offshore Winds
You will understand why wind blowing away from the land turns every paddleboard or inflatable into a potential rescue call, and the simple judgement rule that keeps you close enough to return safely.
Tidal Streams
You will learn how tides flow along the coast like invisible rivers, how their direction changes through the tidal cycle, and how to use them to your advantage rather than being carried away.
Afterdrop
You will learn what happens inside the body after leaving cold water, why warming up incorrectly makes it worse, and the safe routine that prevents collapse, fainting or sudden chill.
Lagoons
You will see how tidal pools and lagoons drain rapidly as the tide falls, forming powerful outflow channels that sweep people into deep water with hazardous entrances, and how to use timing to stay safe.
Headlands
You will discover how water accelerates around headlands, forming powerful currents and hazards that hide behind the rocks, and how to read their shape so you always approach them safely.
Onshore Winds
You will see how wind pushing towards the beach creates heavy shorebreaks, swirling water and powerful returns under the surface, and how timing your entry removes all the risk.
Overfalls
You will discover how tidal flow hitting underwater rock creates boiling water, unpredictable waves and sudden instability—and how to identify overfalls before you drift into them.
Weever Fish
You will learn how venomous weaver fish bury themselves invisibly in warm shallow sand, what happens if you step on one, and the simple treatment that stops the intense pain quickly.
