[4][5] In the breaking event at the 2024 Summer Olympics, Gunn did not receive any points from the judges in each of her three round-robin battles against her opponents, losing 18–0 in all three rounds.
[18][19] As her performance and outfit did not match her competitors' street style, Gunn was subject to widespread criticism online.
[20][21][22] In response, Gunn shared a quote on Instagram: "don't be afraid to be different, go out there and represent yourself, you never know where that's gonna take you".
[9] Team Australia's Chef de Mission, Anna Meares, later issued a statement supporting Gunn and condemning what she called "trolls and keyboard warriors".
The World DanceSport Federation also offered the support of their safeguarding officer in case Gunn was experiencing mental health problems due to the media attention.
[30] An anonymous petition on Change.org, calling for an investigation into the conduct of Gunn, Anna Meares, and the selection process, garnered thousands of signatures.
[1] News.com.au reported in October 2024 that though Gunn gained substantial notoriety at the Olympics for herself and for the sport, other national and international competitors have been trying to distance themselves from her.
[38] She stated that the prospect of being scrutinised by so many online changed her experience of competing and going forward, she will dance mostly for personal enjoyment.
[39] Raygun: The Musical, a theatre work about Gunn's contentious Olympics performance was scheduled to debut in Sydney on 7 December 2024.
The show was cancelled after legal threats by Gunn's lawyers who claimed her name and kangaroo hop were intellectual property.
[41] However, it was reported that the trademark application of the silhouette of her doing the kangaroo pose was submitted by her legal team on the same day of when the show was first promoted with the same image, on 25 September.
