During an interview with Tay FM, the 55-year-old was asked if she was happy to hear the show was returning, with the hosts describing the star-studded finale as a "waste of time".
"Yeah, happy is probably not the emotion," she told the hosts with a laugh. "You know, miffed may have been the word."
Fans were left shocked when Neighbours was cancelled last year after being on Australian TV for almost 40 years, with the finale airing last July.
Kylie and fellow Aussie singer Jason Donovan returned to Australia from the UK to shoot the show's final scenes, with the pair reprising their roles as on-screen couple Charlene and Scott Robinson.
The singer shared that she felt "quite a bit of pressure" to return for the finale and added that her return was not put in place to orchestrate a revival.
"All the affection and love that went into the final episode was truth, so I'm happy for them now. I'm interested to see how it's going to change," she told the hosts.
Kylie added that the producers "genuinely didn't know" the show would continue.
Guy Pearce, who also got his start on Neighbours, shared a similar thought, telling the Sydney Morning Herald's Good Weekend Talks podcast that he was "a little thrown" by the reboot.
During the finale, Guy's character Mike Young moved back to Ramsay St, with the actor adding that he would appear in the reboot for continuity's sake.
"Obviously, if I’m going to extricate myself from the show, I want to do it respectfully," he said. "I wasn’t just gonna go, ‘Well, bad luck. You had your chance, that was it,’ you know. So there may be a little appearance or two, shall we say."
The show is returning with the help of Amazon Prime Video, with The OC's Mischa Barton set to play a "dynamic and unpredictable" character.
