Australian rules football playing field

However, for official Australian Football League matches, strict requirement specifications must be met for stadiums.

Australian rules football grounds, even at the highest level of the game, have no fixed dimensions.

Grounds can vary from long and narrow to almost circular, and are not necessarily symmetrical, depending upon how and where the field was constructed.

[2] Due to possible injuries caused to players moving at high speed by marking, jumping, turning and being tackled without protective padding, the playing field standards imply use of lawn as a surface.

As a consequence of this, there are relatively few fields which were purpose-built for and used by Australian rules football to the exclusion of cricket and all other sports.
