Last weekend, I decided to watch some Friday night football with Dave. Of course, it is completely different than American football. And no, it wasn't actually soccer. First of all, they do not wear any pads or protective gear of any sort. The game also doesn't stop at all when someone gets injured. They basically play around the medical staff. It's barbaric.

With that said, I will allow Wikipedia to better explain the rules...
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." In Round 8, 2008 a new rule was introduced for the remainder of the season. The AFL club has to lodge a piece of paper with an attendant AFL official detailing the player to come off the ground and his replacement.
There is no offside rule nor are there set positions in the rules; unlike many other forms of football, players from both teams disperse across the whole field before the start of play. However, only four players from each team are allowed within the 50 m centre square before 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 (i.e., after a mark or free kick) and during kick-ins following the scoring of a behind.
A game consists of four quarters and a timekeeper officiates their duration. In professional Australian Football, quarters are 20 minutes plus time on. Time on refers to clock being stopped when the ball is out of play, meaning that an average quarter could last for 27 to 31 minutes.
Games are officiated by umpires. Australian football begins after the first siren, the umpire bounces the ball on the ground (or throws it into the air if the condition of the ground is poor), and the two ruckmen (typically the tallest players from each team), battle for the ball in the air on its way back down.
The ball can be propelled in any direction by way of a foot, clenched fist (called a handball or handpass) or open-hand tap but it cannot be thrown under any circumstances. Throwing is defined in the rules quite broadly but is essentially any open hand disposal that causes the ball to move upward in the air.
A player may run with the ball but it must be bounced or touched on the ground at least once every 15 metres. Opposition players may bump or tackle the player to obtain the ball and, when tackled, the player must dispose of the ball cleanly or risk being penalised for holding the ball. The ball carrier may only be tackled between the shoulders and knees. If the opposition player forcefully contacts a player in the back whilst performing a tackle, the opposition player will be penalised for a push in the back. If the opposition tackles the player with possession below the knees, it is ruled as a low tackle or a trip, and the team with possession of the football gets a free kick.
If a player takes possession of the ball that has travelled more than 15 metres from another player's kick, by way of a catch, it is claimed as a mark and that player may then have a free kick (meaning that the game stops while he prepares to kick from the point at which he marked). Alternatively, he may choose to "play on:" forfeiting the set shot in the hope of pressing an advantage for his team (rather than allowing the opposition to reposition while he prepares for the free kick). Once a player has chosen to play on, normal play resumes and the player who took the mark is again able to be tackled.
There are different styles of kicking depending on how the ball is held in the hand. The most common style of kicking seen in today's game, principally because of its superior accuracy, is the drop punt (the ball is dropped from the hands down, almost to the ground, to be kicked so that the ball rotates in a reverse end over end motion as it travels through the air). Other commonly used kicks are the torpedo punt (also known as the spiral, barrel, or screw punt; the ball is held at an angle and kicked, which makes the ball spiral in the air, like a rugby throw, resulting in extra distance) and the checkside punt or "banana", kicked across the ball on the outside of the foot is used to curve the ball (towards the right if kicked off the right foot) towards targets that are on an angle. There is also the "snap," which is almost the same as a checkside punt, except that it is kicked off the inside of the foot and curves in the opposite direction. It is also possible to kick the ball so that it bounces along the ground. This is known as a "grubber". Grubbers can bounce in a straight line, or curve to the left or right.
Apart from free kicks or when the ball is in the possession of an umpire for a ball up or throw in, the ball is always in dispute and any player from either side can take possession of the ball.
The two tall central posts are the goal posts, and the two shorter outer posts are the behind posts.
A goal is scored when the football is propelled through the goal posts at any height (including above the height of the posts) by way of a kick from the attacking team. It may fly through on the full or bounce through, but must not have been touched, on the way, by any player from either team.
A behind is scored when the ball passes between a goal post and a behind post at any height, or if the ball hits a goal post, or if an attacking player sends the ball between the goal posts by touching it with any part of the body other than a foot. A behind is also awarded to the attacking team if the ball touches any part of an opposition player, including his foot, before passing between the goal posts. When an opposition player deliberately scores a behind for the attacking team (generally as a last resort, because of the risk of their scoring a goal) this is termed a rushed behind. Before the start of the 2009 season, this would be the same score as a regular behind. However, because in the 2008 grand final, the Hawthorn Football Club rushed 11+ behinds a new rule was introduced stating that the behind will be counted and the player that rushed the behind will also concede a free kick in the goal square.
A goal is worth 6 points whereas a behind is worth 1 point. If the scores are level on points at the end of play, then the game is a draw; extra time applies only during finals matches in some competitions.
