What constitutes 'interference' during a game?

Interference in netball refers to any action that physically restricts or obstructs an opponent's ability to move freely on the court. This is essential for maintaining fair play and ensuring that all players can contest for the ball without undue hindrance. When a player makes physical contact that limits an opponent's movement, it violates the rules of the game, as it detracts from the fundamental principle of providing each player with an equal opportunity to participate.

In contrast, gestures at opponents, yelling from the sidelines, or playing aggressively do not directly constitute interference in terms of physical limitation. While such behaviors may influence the game or the players' mentality, they do not violate the specific rule regarding physical contact and obstruction during play. Therefore, it is the physical limitation of movement that is at the heart of the definition of interference in netball.
