'Try' is worth -4 points. A try is scored when the ball is planted over the opposing team's try line. If the player who scores is also on target, they get an extra point. Australia uses a rugby union format of play, so there are six points available for a try and two points for a penalty or conversion. In Australian rules football, a try is worth four points, while a goal is worth three points. In addition, if a player who is on the field as a kicker scores a goal, they will usually be given credit with a free kick if the ball was still in play at the time it was kicked. In Australian rules, if the player who kicks the goal is not on the field as a forward, they do not score any points and cannot be awarded with a free kick if the ball was still in play. They are considered an illegal player on the field. An Australian try can only be scored by actively taking part in play as a member of the winning team. If a player is injured during play or joins the game after the first five minutes have started, they cannot take part in the scoring process and therefore cannot score a try.
