After each team has played 22 games of the AFL season, across 23 rounds including a bye, the top eight ranked AFL teams play off in the AFL Finals series to determine the AFL Premiers of the year.
These four weeks of football cut the top eight teams down to two in time for the grand final in the fourth and final week.
Here’s a full explanation of how the AFL finals format works in its current guise.
The first week
The eight teams are typically divided into two groups of four, the top four (1-4) and the bottom four (5-8), who play games among themselves in the first week of finals.
In the top four, first play fourth and second play third in qualifying finals. The higher-placed teams, first and second, have the right to host these finals in their home state.
One of the advantages given to teams in the top four is that they cannot be eliminated if they lose in the first week.
However, the winners of these finals have a bye in the second week and host a preliminary final in their home state in the third week.
Meanwhile, the losers of these finals must play again in the second week and, if they survive that, may have to travel interstate to play their opponent in the third week. So winning a qualifying final is a significant advantage.

Second Qualifying Final: second ranked team hosts third ranked team
In the bottom four, fifth play eighth and sixth play seventh in elimination finals. Again, the higher-placed teams, fifth and sixth, have the right to host these finals in their home state.
As the name suggests, the loser of these finals will be eliminated from the finals series. The winners go on to play the losers of the qualifying finals in semi-finals in the second week.
First Elimination Final: fifth ranked team hosts eighth ranked team
Second Elimination Final: sixth ranked team hosts seventh ranked team
These four games are played across four time-slots: Friday night, Saturday day, Saturday night, and Sunday day.
Typically, the qualifying finals are played in the first two slots, allowing the top four teams the advantage of a longer break than the bottom four.
While finals are identified as the ‘first’ or ‘second’ final, they are not necessarily played in that order.
The second week
In the second week of the finals series two semi-finals are played between the two teams that lost the qualifying finals and the two teams that won the elimination finals.
The teams that won the qualifying finals have a week off, while the teams that lost the elimination finals are out of the running.
The teams that lose these semi-finals will also be eliminated, while the teams that win will go through to face the qualifying final winners in preliminary finals in week three.
The finals series is organised so that the loser of first versus fourth will play the winner of fifth versus eighth, and the loser of second versus third will play the winner of sixth versus seventh.
The losing qualifying final teams are given the right to host these matches in their home state. These games are played across two time-slots: Friday night and Saturday night.

Second Semi-final: loser of Second Qualifying Final hosts winner of Second Elimination Final
The third week
In the third week the winners of the qualifying finals from the first week play the winners of the semi-finals from the second weeks in preliminary finals.
These preliminary finals determine who enters the grand final. The teams who win preliminary finals are through to the grand final, the teams who lose them are eliminated from the finals series.
There are a wide variety of potential preliminary final combinations available depending on how the first two weeks of the finals series pan out.
The winner of the first qualifying final plays the winner of the second semi-final, and the winner of the second qualifying final plays the winner of the second semi-final. This guarantees that it is not possible for any two teams to meet twice in the first three weeks of finals.
The qualifying final winners not only have had a week off as a bye, but also get to host these games in their home state, giving them a significant advantage. These games are played across two time-slots: Friday night and Saturday night.

The fourth week
In the fourth week of finals, the two teams that won the preliminary finals play each other in the grand final. The winner of this match is declared the year’s premiership team.
The grand final could theoretically be between any two teams in the finals series, except for those that play elimination finals against each other in the first week and cannot possibly both progress.
Although one team will be listed first as the ‘home’ team, this fixture does not change venue regardless of the home state of the teams involved.
It has been played every year at the Melbourne Cricket Ground since 1902 except for a few years in the 1940s and once during renovation in 1991. It is always played on a Saturday afternoon time-slot.

The fifth week?
There have been three cases where we’ve been treated to a fifth week of AFL/VFL finals, courtesy of a grand final replay: 1948, 1977 and most recently in 2010.
However, this year the AFL announced their decision to abandon the replay, and, should the grand final finish all-square after four quarters, extra time will be used to decide a premier.
In the case of a tie, the teams will be faced with two five-minute periods of extra time to decide the match. If the sides are still unable to be serparated after the second period, the siren won’t sound, with the next team to score getting the win.
