Ben Roberts-Smith incident

On the 28 February 2012 episode of The Circle, along with George Negus, Stynes made comments about a photo of former soldier Ben Roberts-Smith coming out of a swimming pool, saying, "He's going to dive down to the bottom of the pool to see if his brain is there", while Negus replied in part, "what if [he's] not up to it in the sack?"^[10] After tabloid criticism,^[11] they personally contacted Roberts-Smith who accepted their apology and agreed there was no malicious intent.^[12] Negus said his comments were taken out of context and he was not referring personally to Roberts-Smith.^[13]

On 13 September 2014, Fairfax newspapers issued an apology to Stynes and Negus, stating "Our interpretation was wrong and we accept that both Mr Negus and Ms Stynes were not referring to Cpl Roberts-Smith personally."^[14] News Limited publications, The Daily Telegraph, Herald Sun and news.com.au also retracted the incorrect allegations.^[15]

Kerri-Anne Kennerley incident

On 28 January 2019, Yumi Stynes appeared as a guest panelist on Studio 10 where discussion included Invasion Day. During this Kerri-Anne Kennerley asked "Has any single one of those 5,000 people waving the flags saying how inappropriate the day is, has any one of them been out to the outback where children, where babies and five-year-olds are being raped, their mothers are being raped, their sisters are being raped," to which Stynes responded "That is not even faintly true, Kerri-Anne, and you’re sounding quite racist now." ^{[16] [17]}

Later, while speaking on-air with 2GB's Ben Fordham, Kennerley said Stynes "probably misunderstood" her comments.^[18] The following day Stynes called in "sick" for a booked appearance on Studio 10, stating on Instagram that it was not related to what happened the day before although she later clarified that "the reason I didn't go on the show is because it's not for me to argue Indigenous rights."^[19][20] She also claimed that she "would have been walking into a trap" if she appeared again on Studio 10 the next day.^[21] Stynes instead participated in a radio interview on The Kyle and Jackie O Show, saying "Kennerley has been around forever, she’s like a cockroach, she can’t be extinguished".^[22] During that radio interview, the hosts conducted a phone interview with Kennerley to discuss the previous day's argument, before which Stynes described her as "lecturing me about racism".

The ACMA, in its review of the incident noted that "the emphatic and sweeping suggestion by Ms Kennerley of endemic sexual abuse in Indigenous communities could be capable of provoking strong negative feelings in a reasonable person". ^[23]
