2019 A-League finals series

The 2019 A-League finals series was the 14th annual edition of the A-League finals series, the playoffs tournament staged to determine the champion of the 2018–19 A-League season. The series was played over three weeks culminating in the 2019 A-League Grand Final, where Sydney FC won a fourth championship 4–1 on penalties after a 0–0 draw against Perth Glory.

Matches
The system used for the 2019 A-League finals series is the modified top-six play-offs by the A-Leagues. The top two teams enter the two-legged semi-finals receiving the bye for the elimination-finals in which the teams from third placed to sixth place enter the elimination-finals with "third against sixth" and "fourth against fifth". Losers for the elimination-finals are eliminated, and winners qualify for the semi-finals.

First placed team in the semi-finals plays the lowest ranked elimination-final winning team and second placed team in the semi-finals plays the highest ranked elimination-final winner. Home advantage goes to the team with the higher ladder position.

Elimination-finals
Third-placed Melbourne Victory as the reigning champions took on sixth-placed Wellington Phoenix for the first elimination-final. All three matches from the regular season resulted in draws. Georg Niedermeier opened the scoring for Victory towards the end of the first half, Kosta Barbarouses scored the second as Roy Krishna pulled one back for Wellington, but Ola Toivonen sealing the match to win 3–1 for Melbourne Victory through to the semi-final against Sydney FC.

Fourth-placed Adelaide United took on fifth-placed Melbourne City for the second elimination-final. City were undefeated against Adelaide throughout the regular season. The match went to extra time after a 0–0 draw at the end of 90 minutes, as Ben Halloran scored the winning goal in the 119th minute to win 1–0 for Adelaide as they went through to the semi-final against Perth Glory.
