Kate Middleton and Prince William sent a video message to paramedics, firefighters, police, and other frontline workers to mark Australia's inaugural "Thank a First Responder Day." The Cambridges thanked first responders who battled the country's devastating wildfires in late 2019 and early 2020, as well as those currently fighting the coronavirus pandemic. "Day in, day out, paramedics, police, firefighters, and support staff work tirelessly to keep everybody safe, often risking not only their physical health, but also their mental wellbeing," Kate said in the clip.
