Chaz Mostert Children: Meet Daughter Everly Rose and Learn About His Family With Wife Riarne Marwood

Chaz Mostert is best known for his speed, aggressive racing style and success in Australian Supercars, but away from the circuit, family has become one of the biggest parts of his life. The Australian racing star and his wife, Riarne Marwood, are parents to their daughter Everly Rose Mostert, who arrived in March 2024.

Their journey to parenthood has included enormous happiness as well as heartbreaking loss. Before welcoming Everly, Chaz and Riarne lost their first daughter, Hazel Lola Mostert, who was stillborn in May 2023. They have continued to openly honor Hazel while celebrating the life they are building with Everly.

For people searching for Chaz Mostert children, his family story reveals a much more personal side of the Supercars champion, far removed from race wins, championships and life behind the steering wheel.

How Many Children Does Chaz Mostert Have?

Chaz Mostert and Riarne Marwood are parents to two daughters. Their first daughter, Hazel Lola Mostert, was stillborn on May 3, 2023, at 22 weeks of pregnancy.

Their second daughter, Everly Rose Mostert, was safely born in March 2024 and is the couple’s living child.

The arrival of Everly was especially emotional for the family because it came less than a year after losing Hazel. Riarne described the pregnancy and safe arrival of their younger daughter with deep gratitude, while also making it clear that Hazel would always remain an important part of their family.

Chaz has also spoken publicly about how fatherhood changed his outlook on life and racing. Becoming a dad gave him another reason to appreciate his time away from the circuit and a different perspective on his career.

Who Is Everly Rose Mostert?

Everly Rose Mostert is Chaz Mostert and Riarne Marwood’s daughter. She was born in March 2024, just two days after her father completed a Supercars race weekend at the Australian Grand Prix in Melbourne.

It made for an unforgettable few days in the Mostert household.

Chaz had been competing at Albert Park before quickly returning to be with his family. Riarne later announced Everly’s safe arrival and described their daughter as a dream come true.

Everly entered the world during what became a major period of change for Chaz personally and professionally.

Only weeks after becoming a father, Mostert returned to racing and continued competing at the front of the Supercars field. He later explained that his home life had become an important source of happiness and stability.

While Mostert has spent much of his adult life travelling between race tracks, becoming a parent gave those trips a very different meaning. He openly admitted that being away from his young family could be difficult.

Remembering Hazel Lola Mostert

Before Everly’s birth, Chaz and Riarne were preparing to become parents to their first daughter, Hazel Lola Mostert.

Their lives changed after a routine pregnancy scan revealed a serious problem with Hazel’s heart. Hazel was stillborn at 22 weeks on May 3, 2023.

The couple later shared their grief publicly and spoke about the lasting place their daughter would hold in their lives.

Riarne wrote about the emotional pain of losing Hazel and the love she continued to feel for her. When the couple announced another pregnancy later that year, Hazel remained central to their message.

They described their second daughter as a source of hope following an extremely difficult period.

Their openness also allowed fans to understand why Everly’s safe birth carried so much emotion for the family. It was not about replacing what they had lost. Instead, the couple welcomed another daughter while continuing to remember Hazel as part of their family story.

Who Is Chaz Mostert’s Wife?

Chaz Mostert’s wife is Riarne Marwood, his longtime partner who has been alongside him through many important stages of his racing career.

The pair had already been together for years before starting their family. Riarne was frequently seen with Chaz at racing events, including Supercars functions and major championship weekends.

Their relationship entered an especially emotional period during 2023.

Only days after losing Hazel, Mostert proposed to Riarne. Their engagement was publicly confirmed in June 2023, with Riarne sharing her excitement about spending her future with him.

The couple later welcomed Everly in March 2024.

Chaz and Riarne completed another major family milestone toward the end of that year when they married in December 2024. Their wedding was held near the Queensland and New South Wales border, with several figures from the Supercars community joining the celebration.

It capped a life-changing year in which they had become parents to Everly and officially became husband and wife.

How Fatherhood Changed Chaz Mostert

Mostert has been surprisingly open about how becoming a father changed life away from racing.

After Everly arrived, he spoke about gaining a greater appreciation for mothers and everything involved in raising a newborn. He also joked that instead of slowing him down on the race track, having a child gave him another reason to find more speed.

Behind the humour was a clear shift in his priorities.

Motorsport remains an intense profession. Drivers spend long periods travelling, preparing, training and competing across Australia and overseas. For Mostert, returning home to Riarne and Everly offered a different kind of balance.

That stability appeared alongside one of the strongest stretches of his professional career.

Mostert continued producing front-running performances before eventually achieving the biggest individual prize in Australian touring car racing.

Chaz Mostert Became Supercars Champion

Chaz Mostert finally won his first Repco Supercars Championship in 2025, more than a decade after making his main-series debut.

He secured the title at the Adelaide Grand Final, becoming the 28th driver to win the Australian Touring Car Championship or Supercars Championship.

The achievement added another major honor to a career that already included multiple Bathurst 1000 victories.

His championship also arrived after several years in which his personal life had changed dramatically. He had experienced the loss of Hazel, welcomed Everly, married Riarne and then reached the top of his sport.

For the 2026 season, Mostert moved into another new chapter as Walkinshaw TWG Racing switched to Toyota. He now races the No. 1 Toyota GR Supra, carrying the champion’s number as Toyota competes in Supercars for the first time.

Chaz Mostert’s Family Life Today

Chaz Mostert’s children remain an important part of the story behind the driver fans see every Supercars weekend.

He and Riarne are raising Everly Rose while continuing to honor Hazel Lola’s memory. The family has shared selected moments publicly, although much of their everyday life remains understandably private.

For Mostert, racing may still dominate the public side of his life, but his comments since becoming a father suggest home has become just as important.

From experiencing devastating loss to welcoming Everly, getting married and finally becoming a Supercars champion, the last few years have brought some of the biggest emotional moments of Mostert’s life.

Today, his family story sits alongside his racing success. Everly Rose is growing up with one of Australian motorsport’s most recognizable drivers as her father, while Hazel remains lovingly remembered as part of the Mostert family.
