Three rule changes, all of which were eventually permanently adopted in the VFL, were trialled during this series:,[1]
A free kick was awarded against a player if the ball was kicked out of bounds on the full. Adopted in 1969.[2]
A 50yd square was drawn in the centre of the ground, and no more than four players from each team were allowed within the square during a centre bounce; this was to reduce congestion at centre bounces. Adopted in a modified form in 1973.[2]
