Field
Both the ball and the field of play are elliptical in shape. No more than 18 players of each team are permitted to be on the field at any time.
Up to four interchange (reserve) players may be swapped for those on the field at any time during the game. In Australian rules terminology, these players wait for substitution "on the bench"βan area with a row of seats on the sideline. Players must interchange through a designated interchange "gate" with strict penalties for too many players from one side on the field.
There is no offside rule nor are there set positions in the rules; unlike many other forms of football, players from both teams may disperse across the whole field before the start of play. However, a typical on-field structure consists of six forwards, six defenders or "backmen" and six midfielders, usually two wingmen, one centre and three followers, including a ruckman, ruck-rover and rover. Only four players from each team are allowed within the centre square (50 metres (55 yd)) at every centre bounce, which occurs at the commencement of each quarter, and to restart the game after a goal is scored. There are also other rules pertaining to allowed player positions during set plays (that is after a mark or free kick) and during kick-ins following the scoring of a behind.

Famous quotes containing the word field:
“Wynken and Blynken are two little eyes,
And Nod is a little head,
And the wooden shoe that sailed the skies
Is a wee one’s trundle-bed.”
—Eugene Field (1850–1895)
“There is a call to life a little sterner,
And braver for the earner, learner, yearner.
Less criticism of the field and court
And more preoccupation with the sport.”
—Robert Frost (1874–1963)
“Beat! beat! drums!—blow! bugles! blow!
Through the windows—through doors—burst like a ruthless force,
Into the solemn church, and scatter the congregation;
Into the school where the scholar is studying;
Leave not the bridegroom quiet—no happiness must he have now with his bride;
Nor the peaceful farmer any peace, plough his field or gathering his
grain;
So fierce you whirr and pound, you drums—so shrill you bugles blow.”
—Walt Whitman (1819–1892)
