The 37-year-old also shared details of his new gig to his Instagram.
"Absolutely thrilled to join @ljayes as the new host of Sky News First Edition," he said in his post.
"Laura is one of the best political interviewers in the country and I look forward to working alongside her and the team. I start July 1 and hope you can tune in! @sylviajeffreys has already given me her alarm clock 💤 😁"
The former Channel Nine foreign correspondent left the network in December amid rumours of an imminent axing following a leaked conversation where he was overheard by an Uber driver whinging about the network and his colleagues with his brother, Karl Stefanovic.
