I have no idea how they do it in Netball. In rugby and cricket it is set at 60 percent for players of color. The selectors are in a bind as they are trying to field a strong team and can't. They normally get hammered after world cups for not selecting enough and lose their jobs. The last cricket world cup they dropped a player who was doing very well and the player they bought in was injured and had to leave the field and left the team in a shambles.
