There are three main objectives for the Four Boundary Umpires System.
1. Assist Goal Umpires
In the vast majority of cases there will be at least 1, and often 2, boundary umpires at the behind posts whenever the play is in the vicinity. This will assist goal umpires with scoring shots from close range where the ball travels close to the behind post.
2. Boundary Umpire Decisions
The boundary umpires will to run approximately 50 – 60 metres apart, when play moves around the boundary. This will ensure the boundary umpires will always be close to play which will greatly assist with out of bounds and out on the full decision making. The short kick-in from behinds will also be covered.
3. Reduced Physical and Mental Stress for umpires
Two boundary umpires working on one side of the ground should lessen the physical requirements of what is expected to be a faster, harder running game as a result of the new law allowing an immediate play-on after a behind and the general preparedness of teams to play on quickly. Whilst the complete recovery has been removed, the constant solid hard running of the two umpire system is eased.
