In front of the interchange benches is the "interchange area" (sometimes called the "interchange gate"), which is a 15-metre stretch of the boundary line, roughly centred between the two teams' benches, through which all players must enter and exit the ground when being interchanged. It is marked on the boundary line with two short lines, perpendicular to the boundary, and sometimes with a slanted end. A player who interchanges outside of this area is not permitted to return for the rest of the game.
