In 1919, the VFL competition consisted of nine teams of 18 on-the-field players each, with no "reserves", although any of the 18 players who had left the playing field for any reason could later resume their place on the field at any time during the match.
Each team played each other twice in a home-and-away season of 18 rounds (i.e., 16 matches and 2 byes).
Once the 18 round home-and-away season had finished, the 1919 VFL Premiers were determined by the specific format and conventions of the amended "Argus system".
Key: P = Played, W = Won, L = Lost, D = Drawn, PF = Points for, PA = Points against
All of the 1919 finals were played at the MCG so the home team in the Semi Finals and Preliminary Final is purely the higher ranked team from the ladder but in the Grand Final the home team was the team that won the Preliminary Final.
The Victorian Junior League premiership, which is today recognised as the inaugural VFL reserves premiership, was won by Collingwood's team, Collingwood District. Collingwood District 6.11 (47) defeated University A 4.8 (32) in a challenge Grand Final, played as a curtain-raiser to the senior Grand Final on 11 October at the Melbourne Cricket Ground.
Melbourne returned to the VFL competition, and changed its constitution so that direct payments (i.e., other than "reimbursement of expenses") could be made to players, effectively making the team professional, eight years after the VFL had done so.
The VFL introduced a Second Eighteen competition between its constituent clubs.
At the start of the 1919 season, the VFL had already donated ₤9,436-0-0 to the Patriotic Fund since the start of the war.
In its Round 12 match against St Kilda, South Melbourne set the record for highest score in a quarter, kicking 17.4 (106) in the last quarter of the match. This remains two goals better than any other team has managed as of 2013. South's record score was helped by St Kilda being down to 15 fit players at the start of the quarter, followed up by several Saints players walking off in the course of the quarter.
Other records which have since been broken were set in that same match: South Melbourne full-forward Harold Robertson kicked 14 goals in the match (a record until 1929); South Melbourne kicked a match score of 29.15 (189) (a record until 1931), and a winning margin of 171 points (a record until 1979).
In Round 16, Collingwood defeated Carlton 17.11 (113) to 5.16 (46). No team had scored 100 points against Carlton since Round 1, 1904, a streak of 292 consecutive matches, which remains a VFL/AFL record as of 2017.
St Kilda's win at Collingwood in Round 2 was its first ever win over Collingwood on the road after a winless streak of 24 matches at Victoria Park (20 in the VFL and four in the VFA).
