You’ve probably seen the name Lilie James circulating on social media or in news headlines over the last few years, usually tied to a story so heartbreaking it stays with you. When a tragedy like hers hits the public consciousness, people naturally want to know everything about the person who was lost. They want to know her favorite sports, what she studied at university, and specifically, they want to know about her home life. A common question that keeps popping up in search bars is whether Lilie James was an only child.
Honestly, the confusion is understandable. In the immediate, chaotic aftermath of the 2023 events at St Andrew’s Cathedral School, early news reports were coming out so fast that some details got muddled. People saw photos of a young, vibrant woman and assumed she was the sole focus of her parents' world. But the reality is different.
Setting the Record Straight on the Family Dynamics
Let's get the facts straight right away. Lilie James was not an only child.
She grew up in a tight-knit family in Sans Souci, Sydney, with her father Jamie, her mother Peta, and her younger brother, Max. If you look at the statements released by her father during the most difficult days of their lives, he often mentioned how Lilie would always find time in her packed schedule of coaching, studying, and playing water polo to support her brother.
She wasn't just a sister; she was a pillar for him.
The bond between the two was clearly significant. In 2025, during the coronial inquest into her death, the court heard about a "close and loving relationship" that defined the James household. Lilie was 21—a University of Technology Sydney student with the world at her feet—and Max was her younger sibling who looked up to her.
Why do people keep searching for "Lilie James only child"?
It’s an odd quirk of the internet. Sometimes, when a person is the central figure of a massive news story, the "only child" narrative starts to take hold because the focus is so singular. People project a certain level of preciousness onto victims of crime, and for some reason, the idea of an only child fits that tragic "lone star" archetype.

There's also a high chance of name confusion.
The famous British actress Lily James (of Cinderella and Downton Abbey fame) is often searched for in the same breath. Interestingly, even the Hollywood star isn't an only child—she has two brothers. So, whether you're looking for the Australian water polo coach or the British actress, the "only child" label is factually incorrect across the board.
The Life Lilie Actually Lived
Lilie wasn't defined by being a sibling, though it was a huge part of her identity. She was a powerhouse.
Think about this: she was 21 years old, studying for a Bachelor of Sports Management, working full-time as a sports assistant, and coaching water polo and netball on the side. Most of us struggle to get to the gym twice a week. Lilie was essentially running a professional-grade schedule while maintaining a social life that friends described as "gregarious" and "bubbly."
She attended Danebank Anglican School for Girls from Kindergarten all the way through Year 12. She was a "Danebank girl" through and through. After graduating in 2020, she didn't just disappear into the library; she stayed active in the community. She was the kind of person who walked into a room and the energy shifted. That’s not just "AI-speak" or fluff—her colleagues at St Andrew’s Cathedral School literally described her as a "natural fit" who was "adored by all."
The Shadow of Paul Thijssen
It is impossible to talk about Lilie’s life without acknowledging the reason we are talking about her at all.

Paul Thijssen, a 23-year-old colleague and former student at the school, was the person who took her life. There is a strange irony here regarding the "only child" topic: while Lilie had a brother and a large extended support network, Paul Thijssen was an only child.
The inquest findings from State Coroner Teresa O'Sullivan in late 2025 painted a chilling picture of their brief, five-week relationship. Thijssen was a Dutch national who projected an image of perfection—he was a sports captain, a leader, a "good guy." But underneath that was a "fragile masculinity" that couldn't handle rejection. When Lilie ended things, he didn't move on. He stalked her. He performed "dry runs" of the attack.
He used a "cleaning in progress" sign to lure her into a specific bathroom at the school gymnasium. It was calculated. It wasn't a "crime of passion" or a "momentary snap." It was a cold, premeditated act by someone who felt entitled to her time and her life.
Navigating the Misconceptions
People often try to find "red flags" in hindsight to make sense of the senseless. Some wondered if her family was too overprotective or if being an only child (which we now know she wasn't) played a role in her vulnerability.
The truth is much more uncomfortable.
Lilie did everything "right." She was independent. She had a strong family. She ended a relationship that wasn't working. The tragedy didn't happen because of a lack of siblings or a lack of parental oversight. It happened because of a systemic issue with coercive control and gendered violence.

The inquest into Lilie's death wasn't just about the "who" and "how." It became a landmark case for discussing how young people interact in the digital age.
- Snapchat and Disappearing Messages: The coroner noted that much of the evidence was lost because they communicated on Snapchat.
- Location Sharing: This is a big one. The inquest sparked a national conversation in Australia about how "Find My" apps and location sharing can be weaponized by abusers to track their partners.
- The "Good Guy" Myth: Thijssen didn't look like a monster. He looked like the boy next door. This is why his actions were so shocking to the school community.
What We Can Learn From Lilie's Story
If you came here looking for information on Lilie James as an only child, you now know she had a brother, Max, who she loved dearly. But beyond the family tree, there's a broader takeaway from her life and the legacy her parents, Jamie and Peta, are trying to build.
They have been incredibly vocal about the need to teach young men about respect and the validity of a woman's "no." They don't want Lilie to be remembered just as a victim, but as a catalyst for change.
If you are navigating a relationship that feels heavy, or if you’re worried about someone you know, the "actionable" part of this story isn't about family size—it's about the signs of control.
- Trust the gut feeling: Lilie's friends noticed her withdrawing or appearing stressed during the five weeks she was with Thijssen.
- Audit your digital footprint: Be careful with who has your real-time location. It’s a tool for safety that can quickly become a tool for stalking.
- Support systems matter: Lilie was close to her family, and that closeness is actually what led police to the school so quickly. Her father received a strange text from her phone—sent by Thijssen—and he knew immediately it wasn't her. That connection likely prevented even more trauma by ensuring she was found.
Lilie James was a daughter, a coach, a student, and a sister. She wasn't an only child, but she was certainly one of a kind. Her family continues to honor her by pushing for better education around domestic violence, ensuring that the vibrant girl who loved water polo and dancing is never forgotten.
To better understand the signs of coercive control in young relationships, you can look into resources provided by organizations like 1800RESPECT or the eSafety Commissioner, which focus specifically on digital stalking and emotional abuse. It’s also helpful to look into the "Red Flag" campaigns specifically designed for university students, as these often highlight the subtle behaviors Thijssen exhibited before the situation escalated.
Next Steps for Awareness:
- Research Coercive Control Laws: Many regions are currently updating their legal definitions of domestic abuse to include non-physical control.
- Check Privacy Settings: Review which apps have "Always On" location permissions on your smartphone.
- Educate on "The Ask": Support initiatives that teach healthy relationship boundaries in high schools and colleges.
