On Thursday night, the former Nine breakfast show host announced that he will be joining the Gold Dinner committee for 2019, an annual fundraiser that raises money for the Sydney Children's Hospital.
Taking to Instagram the father-of-three passionately shared the news: "There’s nothing more precious in our lives than our kids. They have our hearts. When they get sick they deserve everything we’ve got. Very proud to be part of the #GoldDinnerCommittee 2019 for the Sydney Children’s Hospital."
Karl ended the post with a hilarious jab at fellow committee member and former MP Julie Bishop: "P.S. in a battle with @juliebishopmp on the night to raise more money. I’m going to smoke her."
Karl's return to social media was welcomed by his legions of fans, who began swarming the comment section with requests for his reappearance on television.
"When is Karl coming back to our screens?" wrote one fan.
"Good to see you posting again Karl I miss you on tv 😝", wrote another.
