In December 2017, Arena joined over 600 high-profile female artists from the Australian music industry, including Missy Higgins and the Veronicas, Sarah Blasko and Jenny Morris, in signing an Open letter "#MeNoMore" demanding change in the music industry, in support of the Time's Up to fight workplace sexual harassment and assault. The authors of the Open Letter state they are motivated to organise the letter as an Australian response to the #MeToo campaign movement triggered by the accounts of sexual abuse in the wider entertainment industry. Sony Music Entertainment, Universal Music Group and Warner Music Group responded with words of support.
