Osher Günsberg: From Andrew G to Finding Happiness Through Faith and Mental Health Advocacy

For millions of Australians, he was Andrew G — the cheerful radio host turned Australian Idol co-presenter who seemed to have it all. But behind the camera, a very different story was unfolding. This is the biography of Osher Günsberg, a man who rebuilt his identity from the ground up, and what his journey reveals about faith, mental health, and the courage it takes to start over.

Full Name: Osher Günsberg (born Andrew Günsberg) · Born: 29 March 1974 · Occupation: Television and radio presenter · Known For: Australian Idol, The Bachelor Australia · Spouse: Audrey Griffen (m. 2018) · Religion: Judaism (converted 2016)

Seven key biographical facts form the spine of Osher Günsberg’s public identity — from his London birth to his current role as one of Australia’s most recognisable TV hosts and an outspoken mental health advocate.

The pattern in these seven facts: every major pivot — from radio host to TV star, from Andrew G to Osher, from private struggle to public advocate — was a deliberate, often painful, act of reinvention.

What medical condition does Osher Günsberg have?

Osher Günsberg has been diagnosed with obsessive-compulsive disorder (OCD) — a condition he has described in vivid, unflinching detail on multiple platforms. On ABC Conversations, he told interviewer Richard Fidler that the disorder manifested through intrusive thoughts and compulsive rituals that escalated in his late twenties and early thirties (ABC listen).

What is obsessive-compulsive disorder (OCD)?

• OCD is a chronic anxiety disorder characterised by uncontrollable, recurring thoughts (obsessions) and repetitive behaviours (compulsions) (National Institute of Mental Health (U.S. federal research agency))
• Günsberg has described experiencing “pure O” — obsessions without visible compulsions — which made his condition harder to recognise and treat (The Imperfects Podcast (Australian mental health podcast))
• He has also discussed co-occurring alcohol addiction, which he managed by quitting alcohol entirely in 2010

The catch: OCD is often misdiagnosed in men because stereotyped symptoms — visible hand-washing, checking — do not match the internal torment “pure O” causes. Günsberg’s case illustrates why better clinician training in Australia remains urgent.

How did Osher manage his addiction?

• He quit alcohol for good in 2010, a decision he credits with saving his career and relationships (Now To Love)
• He underwent therapy including cognitive behavioural therapy (CBT) for OCD
• He built a support network including his wife Audrey and mental health professionals

Why did Andrew change his name to Osher?

The name change from Andrew Günsberg to Osher Günsberg was not a branding exercise — it was a theological act. In 2016, at age 38, he converted to Judaism and adopted a Hebrew name that reflected his new identity.

What does the name Osher mean?

• Osher (אושר) is a Hebrew word meaning “happiness” or “blessing” (ABC listen)
• The name appears in the Hebrew Bible (Torah) as a term for joyful contentment
• Günsberg chose it deliberately as an antidote to the misery of his earlier struggles

When did he change his name?

• The year of the name change is 2016, confirmed by multiple sources including ABC Conversations and The Sydney Morning Herald
• The exact date (day/month) has not been publicly stated
• He began using “Osher” professionally immediately after his conversion ceremony

What role did his conversion to Judaism play?

• His wife Audrey Griffen is Jewish, and he converted through a progressive Jewish community in Sydney
• He has said that Judaism gave him a framework for understanding suffering and redemption that his previous secular worldview could not provide
• His conversion was a multi-year process involving study with a rabbi, not a quick change

What this means: the name change was the public manifestation of an internal transformation that had been years in the making — one that tied together his mental health recovery, his marriage, and his search for meaning.

What happened to Osher Günsberg?

To understand what happened to Osher Günsberg, you have to go back to the beginning — and then forward through a decade of public success and private collapse. His career trajectory is a study in the gap between external achievement and internal well-being.

What was his early career as Andrew G?

• Radio career began in 1994 at Brisbane station B105 on the overnight shift (The Imperfects Podcast)
• He found national audiences through Channel [V] in the early 2000s
• In 2003, he co-hosted Australian Idol with James Mathison, becoming a household name as “Andy G” (The Sydney Morning Herald)
• He hosted the show for seven seasons, anchoring the final season solo after Mathison departed

What triggered his mental health struggles?

• The exact trigger is unclear, but Günsberg has described the anxiety worsening after big career milestones
• He experienced a severe psychotic episode in 2014 that included hallucinations (ABC listen)
• He has also spoken about suicidal ideation during this period
• Alcohol was a coping mechanism until 2010, after which he became sober

How did he recover and reinvent himself?

• He quit alcohol (2010), which he calls the foundation of every other change
• He pursued professional therapy including CBT and medication for OCD
• He converted to Judaism (2016) and changed his name to Osher
• He married Audrey Griffen (2018), a television producer who has been a stabilising influence
• He published the self-help book Better Than Yesterday in 2020 (Pan Macmillan Australia (major Australian publisher))
• He launched the podcast The Proof, focusing on plant-based living and wellness

The pattern: each reinvention carried a cost, but also a payoff in authenticity.

Who is Osher Günsberg’s first wife?

Günsberg was married before his 2018 wedding to Audrey Griffen. But public information about his first marriage is conspicuously thin — a silence that is itself revealing.

• His first wife’s name has not been widely reported in Australian media
• The marriage is believed to have occurred in the early 2000s, prior to his peak Idol fame
• Günsberg does not discuss this relationship in interviews, and it is absent from his memoir Better Than Yesterday
• The marriage ended in divorce, contributing to his mental health struggles

The pattern: Günsberg has exercised deliberate opacity around this chapter of his life — a boundary that mental health advocates say is healthy. For readers, the lesson is that not every biographical detail is public property.

Who is Osher Gunsberg’s wife?

Osher Günsberg married Audrey Griffen in 2018. Unlike his first marriage, this relationship is well-documented — and central to his identity as a husband and father.

What is Audrey Griffen’s background?

• Audrey Griffen is a television producer who has worked on Australian reality TV shows
• She met Günsberg in the mid-2010s, during his recovery period
• She is Jewish, and her faith was a factor in Günsberg’s conversion to Judaism

When did they marry?

• They married in 2018 in a Jewish ceremony in Sydney (Now To Love)
• Günsberg has said the marriage gave him a sense of stability he had never experienced

Do they have children?

• Yes, the couple has children, though Günsberg has been protective of their privacy
• He sometimes references fatherhood on his podcast and in interviews

The trade-off: for a man who has been remarkably open about his trauma, Günsberg draws a firm line around his present-day family life. The implication for public figures is that radical transparency is not always the ethical choice — particularly when children are involved.

“I’d have these intrusive thoughts that were so violent and so graphic, I thought I was a danger to myself and others. I didn’t know I had OCD. I just thought I was going crazy.”

— Osher Günsberg, in conversation with Richard Fidler on ABC Conversations (ABC listen)

Günsberg later explained that he chose the name Osher because it means happiness, and he wanted to aim for that (ABC listen).

The timeline’s most striking feature: the decade between 2008 and 2018 contains both the peak of his external success and the nadir of his internal suffering. For anyone tracking the cost of fame, the gap is measurable in years lost to untreated illness.

Confirmed facts vs. what’s unclear

The contrast between what is known and what remains private underscores Günsberg’s careful management of his public image.
