Radio In January 2006 FitzSimons began co-hosting a breakfast radio program with Mike Carlton on Sydney radio station 2UE. He was brought onto the 2UE breakfast show in an attempt to boost the program's dwindling ratings. However, the Mike and Fitz Breakfast Show still trailed a long way behind the number one program on 2GB, hosted by FitzSimons' former coach Alan Jones.

In the lead up to 2019 New South Wales state election, FitzSimons began a campaign to prevent the demolition of the Sydney Football Stadium and Stadium Australia. He began by launching a petition in late 2017 on Change.org that reached approximately 220,000 signatures prior to the election as well as numerous editorial articles decrying the demolitions. The stadium issue became a major element of the campaign with Labor leader Michael Daley calling the election a "referendum on stadiums".
