THE Australian Open final has arrived as Novak Djokovic looks for an eighth title in Melbourne.
The Serb faces 5th seed Dominic Thiem, who is looking for a maiden grand slam triumph.
But what happens if matches reach 6-6 in the final set?
Does the Australian Open have a fifth set tie-break?
After long final sets in Grand Slam matches, the Australian Open joined Wimbledon and US Open in introducing a tie-break.
Yet, they play a different version to the others.
When players reach 6-6, they compete in a tie-break of first to ten points.
How do fifth sets work at other grand slams?
2019 was the first year ever that each grand slam in 2019 had a different method of deciding a fifth set.
At Wimbledon, a tie-break is only used when the score reaches 12-12.
The US Open has had a fifth set tie-break played under the regular format ever since 1970, while in the French Open players are still required to play out the set until there is a winner by two clear games.
