“The global power of the NCIS franchise became even stronger on broadcast and streaming with the addition of NCIS: Sydney,” said Amy Reisenbach, president of CBS Entertainment. “Our American viewers have fully embraced these engaging characters, unique stories and the fabulous Australian scenery. We are thrilled to bring this show back to CBS next season and spend even more time down under.”
“We’re beyond stoked with the response to the first season of the show, both in Australia and around the world, and that the team at NCIS: Sydney is returning for a second season,” added Morgan O’Neill, executive producer and showrunner for Endemol Shine Australia.
“We’re especially thrilled to invite our audience deeper into the lives of our core team, peeling back the layers to find out what really makes them tick. This will be even more important as we see the bonds of the new family tested to breaking point in the face of a much more potent enemy looming on the horizon.”
NCIS: Sydney stars Olivia Swann, Todd Lasance, Sean Sagar, Tuuli Narkle, Mavournee Hazel and William McInnes.
The series is produced for CBS Studios and Paramount Australia by Endemol Shine Australia and distributed outside Australia by Paramount Global Content Distribution. Morgan O'Neill, Sara Richardson and Michele Bennett are the executive producers.
