Sorry, NCIS: Sydney fans, but tonight's fall finale will no longer be airing as planned. TVLine confirmed on Tuesday, December 16, that the Australia-based procedural won't air season 3, episode 9, this evening. CBS pulled the fall finale hours before it was set to premiere at 9 p.m. ET. The episode titled "South of Nowhere" was set to follow NCIS Special Agent Michelle Mackey (Olivia Swann) and her team as they race to "an Antarctica research base to investigate why a climate scientist killed a colleague on Polar Night Eve - and make it out before their plane engine freezes and they're trapped in darkness for six months," according to the logline. Instead of the planned lineup, flagship series NCIS' fall finale will air as scheduled at 8 p.m. ET and be followed by a rerun of its season 22 episode "Baker's Man," per the outlet. (NCIS: Origins' season 2 fall finale aired earlier this month.) NCIS: Sydney's Olivia Swann Teases Season 3 Treasure Hunt, Alien Abduction CBS has not shared a reason for pulling NCIS: Sydney's fall finale so suddenly, but TVLine reported on Tuesday that the episode will "air at a later date." It is also unknown whether "South of Nowhere" will now serve as NCIS: Sydney's midseason premiere, which was previously slated for Tuesday, February 24, or if the network will release it sooner to keep up with the schedule. Us Weekly has reached out to CBS for comment. Daniel Asher Smith/Paramount+ NCIS: Sydney, which is the first international spinoff in the NCIS universe, premiered in 2023, with season 3 beginning in October. The show's fall finale shakeup comes after tragedy struck Australia on Sunday, December 14, when two gunmen opened fire on Bondi Beach during a Hanukkah celebration, killing 16 people and injuring at least 40. While CBS has not commented on whether the shooting affected NCIS: Sydney's episode airing in America, it wouldn't be the first entertainment venture that has been shifted due to the tragedy. How Many 'NCIS' Shows Are There? It's a Long List The Australian premiere for Avatar: Fire and Ash was canceled on Monday, December 15, to show respect for the lives lost. "Out of deep respect for the victims of the Bondi shooting, the planned Avatar: Fire and Ash premiere event today in Sydney has been cancelled," event organizers told multiple outlets in a statement at the time. "Our hearts are with the community, the victims, their families and loved ones." Australia is currently mourning the losses of those killed and harmed when a father and son armed with bolt action rifles opened fire on Sunday during a midday religious celebration to kick off Hanukkah. Olivia Swann Teases NCIS: Sydney's Season 2 'Mystery' and Mackey's Secret The father was killed on site after being shot by police responding to the shooting. The son, meanwhile, was hospitalized for critical injuries and remains under police guard. The shooting is now the deadliest terrorist attack that's ever been carried out on Australian soil and the deadliest mass shooting in the country since the Port Arthur massacre of 1996. (The Port Arthur attack resulted in gun reforms, restricting the use of firearms nationwide.) Stars included Sydney-born Rebel Wilson have publicly condemned the hateful act. "Just waking up to the news about what's happened on Bondi Beach. An absolute tragedy that is the most un-Australian thing to have happen," Wilson, 45, wrote via social media on Monday. "We shouldn't have gun violence in Australia, we shouldn't have antisemitism - it's not us! Thinking of everyone affected by this devastating violence."
