[14] Peris was sworn into parliament on 12 November, and noted the apology to the stolen generation in her maiden speech.

[17] The newspaper claimed she was conducting an affair with another athlete, and had had sought government funding to arrange a trip together.

[18][19] Fairfax and the ABC reported that Peris was one of the frontrunners being considered to replace Jason Mifsud as head of diversity for the Australian Football League (AFL).

[21] In speeches and in an opinion piece, she argued the reform would include Indigenous Australians in national life more.

In 2012 she became the founder and Patron of the Nova Peris Girls' Academy at St Johns Catholic College, in Darwin.

Peris has actively supported the Australian Republic Movement (ARM) since 1999, serving as one of its two Deputy Chairs by 2022, and its co-chair from March 2023.

[27][28][29] However, by May 2024, she had resigned from the role, saying it had become untenable whilst co-chair, footballer and human rights activist Craig Foster, was making "inaccurate and divisive public statements" regarding Israel and Gaza.

[30] She has been a vocal supporter of Israel, of the Australian Jewish Community, and has been recently noted for her public advocacy against antisemitism.

[31][32] Peris also argued that the Australian Aboriginal flag has been "misappropriated" by Palestine supporters in the Israel–Hamas war protests, a claim challenged by indigenous senator Lidia Thorpe and indigenous academic Chelsea Watego, who noted the history of Aboriginal-Palestinian solidarity in the framework of understanding settler colonialism.

[33] In a 2024 interview with Sky News Australia, she defended her decision to resign from ARM by saying:"I have a duty I feel as an Aboriginal person who has always stood against all forms of racial discrimination, and I hate the rise of anti-Semitism in this country and I feel for the Jewish people and everyone who has been affected..."[34]Peris told the Times of Israel that she could not "just sit back and see young Jewish kids being attacked the way that they are".

[44] As a child, her family attended St Martin De Porres Catholic Community at Casuarina church regularly; she still considers herself a Christian, while keeping an active interest in Australian spirituality.
