KYLIE Minogue admits she's still struggling to comprehend the scale of the moment as the Melbourne-born superstar prepares to headline the Saturday's Grand Final entertainment in a homecoming performance at the MCG.

Minogue will take the stage for a 20-minute set at around 1.30pm before what AFL CEO Andrew Dillon calls "a pretty important game of footy afterwards." 

The lineup also features G Flip, musical actor Michael Paynter singing the national anthem, and a traditional appearance by Mike Brady performing 'Up There Cazaly' during the retiree motorcade.

Despite decades on the world's biggest stages, the pop icon admitted she feels moved, excited and a bit overwhelmed by the enormity of the occassion.

"I don't even know where to start. It's a massive, massive week," she said. 

"We're all in our own little microcosm trying to get this show together, but the scale of it hits you every time.

"Rehearsing the other day, before the main sound system was on, I was doing a sound check with my girls - the other singers - and it suddenly struck me that no one else could hear us. We could hear everything in our in-ears, and I just thought, 'I'm singing on stage at the MCG'. I had that little moment to myself, which was an incredible and beautiful feeling."

Minogue promised her team was pulling out all the stops to deliver an unforgettable, high-energy spectacle for viewers.

"They're getting a Melbourne girl performing in her hometown, which is wild to me," she said. 

"There are some surprises in the show, which I cannot share with you, that are a nod to me being a young girl going to Camberwell High School and dreaming about pop music. Getting to the end of VCE, I'd already started acting, so school didn't make much sense to me anymore. I was faced with questions like, 'What do you want to do? How are you going to live? How are you going to pay bills?' It really shows how far I've come.

"It's led me back to a stage at home in the most iconic venue for the biggest game on the Australian calendar. There's just so much about this moment that is hard to fully grasp, so I'm filled with awe."

While Minogue is keeping the finer details under wraps, fans can expect a carefully crafted set blending some of her biggest hits with a touch of nostalgia and a few surprises.

And although she remained tight-lipped on exactly what's planned, Minogue hinted there will be plenty for fans to look out for.

"For songs, I'm trying to choose songs that people know, with a little bit of nostalgia, songs that are fun, and a few surprises," she said.

"I can't reveal any of them; I've almost lost track of how many there are, but now that they're built into the performance, they just feel second nature.

"There are definitely a few Easter eggs in store."

Despite her decades as a global superstar, Minogue remains humbled by the scale of performing at the Grand Final.

"I've stepped onto big stages in these kinds of places, but not having to get my stage on and off and all the other complications and challenges," she said.

"So, luckily, we pressed go on a few things when we did, because even the most mundane things such as manufacturing, availability and logistics take time.

"The list goes on and on. So, creative ideas are at the heart of it, and then, yeah, the execution does take a long time."
