Surf lifesaving is a multifaceted social movement that comprises key aspects of voluntary lifeguard services and competitive surf sport. Originating in early 20th century Australia, the movement has expanded globally to other countries, including New Zealand, Ireland, South Africa, and the United Kingdom. Surf lifesavers in Australia are colloquially known as "Clubbies".

A lifeguard is a rescuer who supervises the safety and rescue of swimmers, surfers, and other water sports participants such as in a swimming pool, water park, beach, spa, river and lake. Lifeguards are trained in swimming and CPR/AED first aid, certified in water rescue using a variety of aids and equipment depending on requirements of their particular venue. In some areas, lifeguards are part of the emergency services system to incidents and in some communities, lifeguards may function as the primary EMS provider.
