The age group for football in Australia is based on calender years (1 January to 31 December). For the junior age groups, if a player turns 7 in the calendar year, then their default age group is U7.

Players can play up a year to be with friends for U6-U11, but will be graded into the right age group from U12 up, with exceptions only to facilitate a team short of players or for physically mature players.

To play in the over 35 competition, players must turn 36 or older in the calendar year.
