Here is what the page “Why NCIS: Sydney Is Missing Tonight (October 6) and When Season 4 Premieres” contains. Fans of the NCIS franchise are in for a treat tonight, October 6, 2026, as the popular procedural returns to CBS. However, viewers eagerly awaiting a new episode of NCIS: Sydney will be disappointed to find it absent from the lineup. The Australian-set spinoff, which has garnered a dedicated following since its debut, is not airing tonight for a specific scheduling reason that has left many wondering when they can expect new episodes.
The absence comes as a surprise to some, given the franchise's coordinated rollout strategy, but it underscores the unique production and broadcast timeline for the international co-production. NCIS: Sydney, which films in Sydney, Australia, has faced distinct scheduling challenges compared to its U.S.-based counterparts. While the flagship NCIS and other spinoffs return tonight, Sydney's third season concluded earlier this year, and the show is currently in production for its fourth season. The full version stays on the original page, which this listing opens directly.
