THE 2020 NAB AFL Women's competition will stop immediately and no premiership cup will be awarded.
The decision was made on Sunday after Prime Minister Scott Morrison announced restrictions would be placed on travel.
"Today’s AFLW semi-final between Carlton and Brisbane Lions will be the last NAB AFL Women’s match to be played with the 2020 season ending today," McLachlan said.
"Given the twin conference structure and that the finals series was not completed, the AFL Commission has determined no premiership will be awarded for this season, following a recommendation from the AFL Executive."
McLachlan said the worsening situation and the decision by various State Governments to close their borders meant it was time for the AFL to immediately stop the AFL and AFLW competitions.
The AFL Executive discussed ways to potentially award a minor premiership of sorts, but ultimately accepted that not awarding a cup was the outcome that had to happen.
Major financial repercussions will be felt across both competitions, with discussions surrounding the next step for the League and clubs set to happen over the next 48 hours.
