They aren’t going to shake off this backlash.

Australian Swifties were feeling some serious “Bad Blood” following a “bizarre” and “terrible” Taylor Swift tribute concert where performers read cue cards on the ground and swore in front of children.

“Worst concert I’ve ever been to,” fumed aghast attendee Saga Wessman on Facebook while torching the event, which went down Sunday at the Night at the Barracks in Manly, Australia.

Dubbed “Taylor Made: A Celebration of Taylor Swift,” the Fyre Festival-esque affair was organized by feminist firebrand Clementine Ford, 43, after she failed to procure tickets to Swift’s Australian Eras Tour earlier this year.

In accordance, the performance was billed as a concert for those who missed out on the pop star’s stint Down Under, and featured local artists such as Alex the Astronaut, Charley, Clare Bowditch and Lucy Durack.

Unfortunately, the cover concert — where tickets cost up to $100 — fell flat on its face with many disappointed guests flocking to social media to trash the botched bash.

Many criticized the performers for reading lyrics from the ground and making the crowd sing the songs because they were “too hard.”

“There was just no effort,” said concertgoer Anna Green, who took her daughter to the show.

“For $130 I’m expecting a polished performance, but it looks like they put it together in about three days,” she fumed. “The main performer didn’t know the words and she looked very uncomfortable. It was karaoke.”

Green ended up leaving the “terrible” tribute early and has since lodged a formal complaint to the Barracks.

Savannah Brown, 25, said she was stunned to see so many kids at the venue despite advertisements recommending “Taylor Made” for people aged 13 and older due to its “adult themes, humor and some swearing.”

“She’d sing a [Taylor Swift] song about heartbreak and then be like, ‘Don’t let people hurt you kids!’ ” Brown said while criticizing Ford’s performance. “It was so bizarre, you’re not Taylor Swift.”

Ford and friends also sang songs from early in the “Antihero” singer’s career, which resulted in awkward silences from the audience, many of whom weren’t alive when she wrote the tunes.

“On the bus home, my friend turned to me and said is this our Willy Wonka experience?” said Brown, referencing the notorious event in Scotland that went viral due to its shambolic setting and glum-looking performers.

Parents were also appalled by Ford’s frequent use of profanity during her post-performance speeches. “My 7-year-old’s core memory is Clementine Ford swearing while she was speaking to the crowd, not ideal,” griped Aoife O’Connell.

While the price was a definite step down from the real deal — tickets to the upcoming US and Canadian legs of the Eras Tour start at north of $1,000 — fans were nonetheless demanding refunds.
