What is the role of the co-umpire during a netball match?

The co-umpire plays a crucial role in netball by serving as the umpire who is not currently controlling play at any given moment. This means that while one umpire may be making decisions about play, the co-umpire has the responsibility to support this decision-making process and oversee any other aspects of the game that require attention.

This dual-umpiring system allows for a more comprehensive officiating experience, helping to ensure that the game is fair and that rules are being followed effectively. The co-umpire can focus on observing the overall flow of the match, spotting any violations, and ready to step in if necessary. This collaboration between umpires enhances the quality of officiating, reduces the likelihood of errors, and helps maintain the tempo of the game.

The other options do not capture the essence of the co-umpire's role accurately. The primary purpose of the co-umpire is not to control the match at all times, consult directly with players, or merely stand by the sidelines, but rather to assist and be ready to take over when needed, ensuring effective officiating.
