The Grammy winner will take to the stage for the first time in Australia on Wednesday night at Rod Laver Arena and fans cannot wait.

Sunrise reporter Andrew McCormack met some of the dedicated fans outside the venue and told the show about 200 fans were waiting.

With 12 hours to go, he said some fans, both local and interstate, had been camping around the arena for days to get as close as they could.

Video showed tents perched in the aisles around the arena in makeshift campsites.

“Someone in every one of these aisles,” McCormack said.

When he asked a group of girls why they were so dedicated, one told Sunrise: “Olivia’s one of my favourite artists, she’s so incredible.

“Her lyrics especially, hearing her live is just such an incredible once-in-a-lifetime opportunity.

“She puts on such a great performance, she’s such a performer, the backup dancers are so talented as well.”

The display of fan devotion comes a few days after Rodrigo was spotted on the streets of Collingwood in Melbourne ahead of her concerts.

TikTok user Bianca Camiolo spotted the singer and approached her to ask advice for an aspiring artist — she then shared the encounter on the social media platform.

“Oh my gosh! Just make stuff every day, keep going until you have good quality,” the US star told Camiolo.

The singer kept it casual in a New York Yankees baseball cap, grey coat, white sweater and black jeans, paired with black Converses.

Fans gushed over the video.

“The most genuine person I ever know, so humble and down to earth,” one fan said.

Another wrote: “You’re so lucky!”

“Oh my GOD, she’s out here somewhere,” another fan added.

Rodrigo will perform at Melbourne’s Rod Laver Arena on Wednesday, Thursday, Sunday and Monday before taking to the stage at Qudos Bank Arena in Sydney on October 17, 18, 21 and 22.

The tour is set to be Rodrigo’s first-ever run of shows down under, with New Zealand singer Benee, best known for her hit Supalonely, set to join the star as the opening act in Australia.

Rodrigo first became known for starring in Disney’s High School Musical: The Musical: The Series, but shot to fame following the 2021 release of her debut single Driver’s Licence, which topped the US Billboard Hot 100.

She released her first album, SOUR, later that year and was named Entertainer of the Year by TIME Magazine. Her second album, GUTS, followed in 2023, again topping the charts in the US, Australia and around the globe.
