“When I see some of that footage back, I’m still as confounded as I was even as a 19-year-old,” she said.
“Sometimes it felt like just humiliation and having to sit within that frame and handle it.”
She said she did not believe such treatment would happen in the same way today, though noted that social media had created different pressures for public figures.
Minogue said making the documentary had required her to put aside her nerves and revisit moments she found painful.
“In the end, I just had to take the plunge and really open myself up a little more,” she said.
The singer added that she hoped to return to acting in future, alongside continuing to make music, which she described as “a best friend” and “a saviour”.
Minogue also hinted she could return to Hyde Park after recalling a previous 2024 performance there.
“I’ll see you again at Hyde Park,” she said, before adding: “I said that like I’m assuming I’m going to play Hyde Park again. Maybe I will. It was amazing.”
