had many effects on the organisation of football in Australia:
Geelong was unable to compete in the competition because of wartime travel restrictions. Temporary transfers to other clubs were available to Geelong players.
Melbourne and Collingwood struggled to field a team, and at one stage considered amalgamating into a joint team, however they were both ultimately able to compete.
Hawthorn and Collingwood withdrew their teams from the reserves competition.
Available servicemen were often called upon to make up the numbers - this accounts for the drop in form of the Melbourne team, having previously won three premierships in a row.
The VFA went into recess, and any eligible players were given temporary league permits.
In 1942, the VFL competition consisted of eleven teams of 18 on-the-field players each, plus one substitute player, known as the 19th man. A player could be substituted for any reason; however, once substituted, a player could not return to the field of play under any circumstances. Teams played each other in a home-and-away season of 16 rounds. The determination of the 1942 season's fixtures was complicated by the fact that when the VFL decided to proceed with senior football on 1 April, it was not known which grounds would be available. All 1941 grounds except Windy Hill and the Brunswick Street Oval were candidates for long-term appropriation by the military, and the VFL announced that unless three grounds were available, it would not play the season. Consequently, each round's fixture through the first eleven weeks was set only on the previous Wednesday week, rather than being pre-determined at the start of the season. Ultimately the Melbourne Cricket Ground, the Lake Oval, the Western Oval, and the Junction Oval all became unavailable; but, several Victorian Football Association grounds became available when the VFA announced on 21 April that it was going into recess, resulting in St Kilda and Footscray moving to Toorak Park and Yarraville Oval respectively, and the remaining ground losses were managed by Melbourne sharing the Punt Road Oval with Richmond and South Melbourne sharing Princes Park with Carlton. During the first eleven rounds, each team played each other once and had one bye. The remaining five rounds featured the same matches as Rounds 1 to 5. This resulted in an uneven fixture in which six teams played 15 matches, and five teams played 14 matches. Teams were awarded four premiership points for each bye, so the teams with an extra bye were favoured by this draw. Once the 16 round home-and-away season had finished, the 1942 VFL Premiers were determined by the specific format and conventions of the Page-McIntyre System.
The VFL's leading goalkicker was Lindsay White of South Melbourne with 67 goals ; White usually played for Geelong, but transferred to South Melbourne because Geelong had withdrawn from the war-time competition.
The seconds premiership was won by. St Kilda 13.10 defeated 7.15 in the Grand Final, played as a stand-alone match on 12 September at the Punt Road Oval.
Notable events
In Round 2, Melbourne and Richmond set the record for the highest aggregate score in a game, with the teams combining for 48.25. This record would stand for thirty years, eventually being broken in the 1972 Grand Final.
Melbourne was led on to the field by RAAFair aceSquadron Leader Keith "Bluey" Truscott, DFC and Bar. Truscott unfurled Melbourne's 1941 premiership flag and, very obviously lacking match condition, played an average game, kicking a single goal in his team's 79-point loss, which proved the last of his fifty career senior games).
The second half of the 1942 Grand Final was delayed as the captains Jack Dyer and Dick Reynolds, both of whom were in "reserved" occupations and, therefore, exempt from military service, made speeches to the crowd in support of the wartime Austerity Loan.
On Saturday, 26 September, the premiers, Essendon played a patriotic match against a Combined Services Team that included former VFL stars Laurie Nash, Bob Pratt and Ron Todd. Essendon won 24.18 to 20.15 before a crowd of 10,000 at Princes Park.
Hawthorn recorded its only win of the season over Collingwood in Round 5, the first time that the Hawks had beaten the Magpies since they joined the VFL in 1925 after 29 losses. Hawthorn were to lose nineteen in a row to the Magpies between 1944 and 1954 before its first peacetime victory in Round 4, 1955.
