Gretel Killeen: Big Brother Host and Her Life Now

For a generation of Australians, Gretel Killeen was the voice of Friday-night evictions on Big Brother. Two decades later, she’s trading the diary room for a world map—racing alongside her daughter on The Amazing Race Australia: Celebrity Edition.

Born: 3 February 1963 · Birthplace: Turramurra, NSW · Occupation: Television presenter, comedian, author · Known for: Host of Big Brother Australia (2001–2007), The Traitors Australia · Instagram: @gretelkilleen · Website: gretelkilleen.com.au

Seven key facts, one pattern: most of Gretel Killeen’s biographical details are well-documented, but her personal life—especially family specifics—remains deliberately private.

What does Gretel Killeen do now?

Hosting The Traitors Australia

According to Gretel Killeen’s official website (first‑party source), she is the host of The Traitors Australia. New Idea (Australian entertainment magazine) reported in November 2025 that Killeen would return to TV in that role on Channel 10 in 2026. However, IMDb (crowdsourced film database) lists Rodger Corser as the host of The Traitors Australia, creating a discrepancy that has not been officially clarified. Killeen’s site remains the primary source crediting her as host.

Writing and authoring books

Killeen continues to write and publish books, having released multiple titles throughout her career. Wikipedia (crowdsourced encyclopedia) lists her as the author of several works, though specific recent publications are not detailed in public records.

Social commentary and journalism

In addition to television, Killeen works as a social commentator and journalist, contributing to various Australian media outlets. Wikipedia notes her role as a media personality who appears on panel shows and comment pieces.

The implication: this host-credit mismatch may delay or alter Network 10’s promotional plans for the 2026 season.

Who is Gretel Killeen’s daughter on The Amazing Race?

Daughter’s name and background

10 Play (Channel 10’s streaming service) identifies the pair racing in The Amazing Race Australia: Celebrity Edition as Gretel Killeen and Epiphany Mason. The Paramount ANZ (official network press release) describes Epiphany as someone who followed her mother into media, suggesting she is pursuing a career in the entertainment industry.

Appearance on The Amazing Race Australia

Killeen and Mason were announced as contestants for the celebrity edition in March 2025. According to Wikipedia, the pair were eliminated 6th in Wulai District, Taiwan. Killeen’s official website confirms she competed with her daughter.

The pattern: a retired reality host returns not as a host but as a contestant, letting her daughter introduce her to a new audience.

How old are Gretel Killeen’s children?

Number of children

Public records, including Wikipedia, state that Killeen has two children. One of them, Epiphany Mason, is documented in media coverage of The Amazing Race. For more on Australian television personalities who have balanced family and public life, see Shane Jacobson’s biography.

Ages and approximate birth years

Exact ages have not been publicly confirmed. Based on Epiphany’s description as someone who “followed her mother into media” (Paramount ANZ), she is likely in her late teens or early twenties. No reliable information exists about Killeen’s second child.

Is Gretel Killeen married?

Current relationship status

Gretel Killeen has not publicly stated that she is currently married. Wikipedia and her official website make no mention of a spouse, suggesting her marital status remains private.

Past relationships

No credible sources document past marriages or long‑term partnerships. Killeen has kept her romantic life out of the public eye.

Who is the father of Gretel Killeen’s children?

Known details about the father

The identity of the father has never been publicly disclosed by Killeen or any other reliable source. Wikipedia does not list a partner or former spouse.

Public statements or lack thereof

Unconfirmed media speculation exists, but no verified information has emerged. The absence of any official statement on this topic suggests Killeen intentionally protects her children’s privacy. Another Australian comedy icon with a similar approach to privacy is Russell Coight, whose personal biography remains largely under wraps.

Gretel Killeen’s career arc—from the Big Brother diary room to racing around the world with her daughter—reflects the shifting nature of Australian reality television. For Network 10, banking on nostalgia while introducing a new family dynamic may prove a winning formula. For viewers, the biggest open question remains whether Killeen will take the Traitors throne in 2026, or whether the conflicting credit signals a different plan behind the scenes.
