Fans responded that it was “embarrassing” and “political correctness gone into new levels not seen”.
The officers’ vests feature a phone number to “report antisocial behaviour”.
A fan tweeted he was “surprised no one has called the hotline and dobbed in two blokes walking around trying to ruin everyone’s fun”.
One Instagram user asked whether there were Winx-like odds that the behavioural awareness officers would get the “bald-headed flog treatment” next time.
Hawthorn supporter Vic Ghiller told The Age the officers were at Marvel Stadium Friday night.
“They were actually patrolling the Hawthorn cheer squad and telling supporters to calm down,” he said.
“As a long-term follower of AFL, I am losing interest in AFL and seriously thinking of only attending VFL as it’s more user friendly.”
Marvel Stadium chief executive Michael Green said the behavioural awareness officers had been in place all year.
“They have been called ‘behavioural awareness officers’ and worn those same vests all year,” he said.
