IN Australian rules football, zoning (originally called district football) refers to a system whereby a given area, either region or lower-level football league, is reserved exclusively for one club.ZOning has been historically an important part of most major Australian football leagues, being usually justified as necessary to ensure a reasonably equitable competition. IN the early days of Australian rules football, players, though required to be amateurs, were free agents.
