affected separate state league finals on the exact same day: the 2018 SANFL preliminary final, when the league had no recourse to change the result of a game won by a North Adelaide team which fielded 19 men for several crucial final quarter minutes without a head count; and the 2018 NEAFL grand final (described below) when premier Southport was caught with 19 men on the field in a head count in the opening seconds of the final quarter. In recent years, the majority of incidents of extra players on the field have been an error by a player who was meant to go to the bench after an interval, hence the shift in rules from cancelling the team's entire score to just cancelling the score for that quarter, but with the provision for further penalty as appropriate.
