The 28-year-old pop megastar was performing in the Australian city on Monday (13.02.17) when her instruments were left without any sound and she was forced to entertain her adoring fans with a "filthy joke" whilst her crew tried to fix the problem.
She said on stage: "Shall I tell you my filthy joke despite all the children here? I need more applause than that because I might offend someone.
"What do you call a blonde standing on her head? A brunette with bad breath."
The 'Hello' hitmaker was left chatting with the audience for five minutes after performing 'Sweetest Devotion', as she claimed she wasn't "quite sure" what the issue was.
She continued: "So we're having a technical difficulty. I'm not quite sure what it is. Shall I try and tell some jokes?
"Our power has gone out under the stage, so who knows how long we're going to be doing this for."
Later in the show, the 'Someone Like You' singer then revealed the technical malfunction had come as her special revolving stage had inadvertently caused a vital plug to have been pulled out.
She confessed: "I'm sorry about the power cut tonight.
"You'll never guess what it was? So you know the band's stage starts revolving after a little while, well as the stage revolved it pulled the power plug out so all the instruments went off.
"I won't be revolving that stage again will I! I've had an amazing time.
"Thank you for your patience with my absolutely useless banter and thank you for putting up with some terrible jokes."
It's not the only part of Adele's show which has had to be scrapped either, as she recently put a stop to the use of fireworks after her four-year-old son Angelo - whom she has with her husband Simon Konecki - was hit in the eye by a piece of debris during rehearsals.
She said at the time: "We've been rehearsing here and up until last night we had fireworks for you.
"And obviously everyone likes a fireworks display. However, my son was watching in the crowd ... there wasn't much of a crowd, there was like five people.
"A bit of debris - it wasn't big - but a bit of s**t went in his eye and he was very upset, so I got rid of the fireworks."
