Nova radio host Tim Blackwell's girlfriend, Lizzie Baxter, posted a Father's Day tribute on Instagram on Sunday, calling the 42-year-old broadcaster "daddy" and sharing a photograph of Blackwell with his three children.
Baxter, 28 and a producer on Nova's Fitzy & Wippa, uploaded the image on Sept. 7, 2025, alongside the caption: "Happy Father's Day to our daddy!! Because I'm young enough to be your daughter too!!" The photograph shows Blackwell with his sons Bo, 12; Alfie, 9; and Artie, 6.
Blackwell and Baxter have been publicly linked since last year. The couple made their red carpet debut at the ARIA Awards in November 2024, where Blackwell was hosting and confirmed to Daily Mail Australia that Baxter was his date. The pair have since appeared together at industry events and on social media.
Blackwell, a long-serving presenter on Nova networks, shares his three children with his former wife, Monique. The relationship between Blackwell and Baxter, who is 15 years his junior, has drawn attention in entertainment coverage due to the age gap and Baxter's role behind the scenes at the radio network.
Baxter's Instagram tribute follows a pattern of personal posts that have intermittently documented the couple's time together and family moments since they went public. The post prompted commentary from followers and circulated in entertainment reporting on Monday.
Neither Blackwell nor Baxter issued additional public statements beyond the Instagram post. Representatives for Blackwell did not immediately respond to requests for comment.
The exchange comes amid continued public interest in the private lives of media personalities and the boundaries between professional and personal roles within broadcasting. Blackwell remains a visible figure in Australian radio, regularly participating in live events and award ceremonies, while Baxter continues her production work for Nova.
The Father's Day post adds to a sequence of public appearances and social-media disclosures that have mapped the couple's relationship from its public debut at the ARIA Awards to routine family moments shared online.
