On 9 May 2017, it was announced that FremantleMedia had renewed Wentworth for a sixth season, set to air in 2018.
FremantleMedia's Director of Drama, Jo Porter, said "Getting to a sixth season is something none of us take for granted. Key to this is the unwavering dedication to the show by the incredible Wentworth audience both in Australia and around the world. Like us they are drawn to our exceptional cast who embody the diverse, complex and intriguing characters who populate the intense world of Wentworth and its high stakes and compelling stories."
Foxtel's Head of Drama, Penny Win, mentioned, "As Foxtel's longest-running original drama (originally created by Channel 10 as "Prisoner" in 1979), Wentworth continues to set a high bar for our local production slate. With season five premiering in Australia on Foxtel, there is much yet to unfold. My lips are sealed about the sixth season details. Marcia Gardner and the writers excel in setting up intriguing story arcs and crafting finely scripted narratives for the wonderfully talented Wentworth cast."
