Having shared the role of hooker with Damien Cook in 2017, Farah was demoted to reserve grade with the North Sydney Bears at the start of 2018, with Cook taking on the role full-time. Farah later said he considered retirement during this time. "I just didn’t want to be there. It was hard, mate. Really hard. I don’t want to disrespect Norths because they are a great club … but it was embarrassing for me. You get there, you get heckled by the crowd. There's always a smart-arse." Farah made his first appearance for Souths in their Round 13 victory over Cronulla, filling in while Cook played State of Origin. Despite his absence from first grade, Farah was praised for his performance which included "a whopping" 62 tackles.
