Summary
Navigation (Collision) Regulations - Federal maritime safety regulations establishing the rules of the road for vessels in Australian waters to prevent collisions. Likely incorporates or supplements the international COLREGs (International Regulations for Preventing Collisions at Sea). Covers vessel lights, shapes, sound signals, and steering/sailing rules.
Reason
Maritime navigation rules address a genuine coordination problem where individual vessel operators cannot solve through voluntary arrangements alone - all participants must follow identical rules for them to work. Without standardized collision avoidance rules, Australian waters would face increased risks of vessel collisions, property damage, loss of life, and environmental harm from maritime accidents. These regulations largely implement internationally binding COLREGs standards that Australian vessels must follow anyway to operate globally. While compliance costs exist, the externality costs of collisions (death, pollution, property loss, disrupted commerce) substantially outweigh regulatory burden. Deletion would leave a critical gap in maritime safety coordination.
