Primary contact (in-water) recreation
Involves water contact activities where the whole body, face and/or trunk is frequently immersed; or where the face is frequently being sprayed; or where it is likely that some water will be swallowed, inhaled, or come into contact with ears, eyes, mouth and nose or cuts in the skin (e.g. swimming, water skiing, jet skiing and tubing).
Secondary contact (on-water) recreation
Involves incidental water contact activities in which only the limbs are regularly wet, and greater contact with water (including swallowing) is unusual (e.g. boating, fishing, rowing, kayaking or canoeing with no intent to capsize or submerge). There may be the occasional and inadvertent immersion through accidents. (e.g. slipping into the water, accidentally capsizing from a rowing or sailing craft).
