How long is the suspension for a red card?

Indirect red card (a second yellow in the same match): a mandatory one-match suspension, served in the club's next A-Leagues match.

Direct red card: the mandatory suspension depends on how many direct reds the player has accumulated in the regular season or finals series:

This is the minimum. The Match Review Panel or Disciplinary and Ethics Committee can add further matches for the offence under the Table of Offences. For example, assault of a match official carries a minimum of six months. Team officials (such as coaches) have the same direct red card scale.

Direct red card offences include serious foul play, violent conduct, biting or spitting, denying a goal or obvious goal-scoring opportunity, and offensive, insulting or abusive language or gestures.
