Karl Puschmann: entertainment reporter on SafeWork NSW launching a wider investigation into Married At First Sight Australia - Heather du Plessis-Allan Drive

The latest season of Married At First Sight Australia has been plagued by scandals on and off the screen - and now a regulatory body has launched a wider investigation.

SafeWork NSW is investigating Channel 9 and production company Endemol Shine, generating uncertainty over the future of the series.

Entertainment reporter Karl Puschmann says this investigation follows an incident where one of the grooms allegedly punched a wall in frustration - prompting safety concerns for the impacted cast members.

"By all the accounts that have been on the show, it does sound pretty serious - you can't go around punching walls just because you're a little bit upset about something. And the show's response hasn't been particularly great either."
