Chaz Mostert Wife: Meet Riarne Marwood, Her Career, Family Life and Relationship

Riarne Marwood is best known publicly as the wife of Australian Supercars star Chaz Mostert, but her connection with motorsport goes back years. Long before their wedding, she was regularly seen alongside Mostert at racing events, awards nights and important moments away from the track.

Their relationship has gone through celebrations as well as deeply personal challenges. Mostert and Marwood became engaged in 2023, welcomed daughter Everly Rose in March 2024 and married later that year. Their wedding brought a memorable close to an eventful period in their lives.

While Chaz’s racing career naturally receives much of the attention, Riarne has developed her own public profile through motorsport appearances, social media and earlier work connected with beauty and lifestyle interests. Still, she keeps many details about her background private, so several frequently repeated claims about her age, height and personal wealth remain difficult to independently confirm.

Who Is Riarne Marwood?

Riarne Marwood is an Australian public personality who became familiar to Supercars followers through her relationship with Chaz Mostert.

She had already appeared around the motorsport scene before becoming widely known as Mostert’s partner. Supercars coverage from the 2017 Gala Awards, for example, identified Marwood alongside Mostert on the red carpet. That gives their relationship a considerably longer public history than some newer biographies suggest.

Marwood has also been associated with the beauty and lifestyle space. Earlier reports described her as having participated in the Miss Supercars competition and working in the beauty industry. However, detailed information about her professional career is relatively limited compared with what is publicly available about her husband.

Today, much of the interest surrounding her comes from family life and her regular connection with Australia’s Supercars community.

Riarne Marwood’s Age and Early Life

Some online biographies list Riarne Marwood as being born in 1993 in Australia. However, a complete date of birth has not been established through stronger public sources, which makes claims about her exact age difficult to confirm.

Her childhood, parents and siblings have also remained largely outside the public eye.

There are similarly limited reliable details about where she attended school or what she formally studied. Claims that she studied business or lifestyle management have circulated online, but they are not strongly documented in established public records.

That lack of information is not particularly surprising. Marwood became known mainly through motorsport rather than through a traditional acting, television or entertainment career where personal biographies tend to be heavily documented.

She appears to have deliberately kept much of her family background private even as her public visibility increased.

Did Riarne Marwood Work as a Model?

Riarne has occasionally been described online as a model, although describing her solely as a professional model may give the wrong impression.

Earlier coverage connects her with the Miss Supercars competition, and she has made numerous appearances at motorsport functions and formal events. Her fashion and lifestyle-focused social media presence has also contributed to the perception that she has worked within modeling and promotional circles.

Some older reports also linked her with work as a beauty therapist.

What is clearer is that Riarne has become comfortable in the public-facing side of motorsport. She has attended racing functions, awards ceremonies and major events alongside Chaz, giving fans occasional glimpses of their relationship outside the race weekends themselves.

How Did Riarne Marwood and Chaz Mostert Meet?

The couple has not publicly provided an extensive story explaining exactly how their romance began.

They were certainly together publicly by 2017, when Riarne accompanied Chaz to the Supercars Gala Awards. They continued appearing together in subsequent years as Mostert’s career developed.

Their relationship eventually became familiar to Supercars followers, with Riarne frequently supporting Chaz during important racing moments.

Chaz Mostert has established himself as one of Australia’s prominent touring-car racers, including multiple Bathurst 1000 victories. Yet his comments about Riarne have occasionally shown how important his personal life is beyond race results and championship points.

During a difficult period in 2023, Mostert publicly acknowledged the importance of Riarne’s support, describing her as a major presence behind him during a challenging year.

Their Engagement

Chaz Mostert proposed to Riarne in May 2023 during a sunset walk.

The engagement came during an emotional period for the couple. They had recently experienced the stillbirth of their daughter Hazel Lola at 22 weeks.

Riarne later publicly shared the engagement news, explaining that she had no hesitation in accepting Chaz’s proposal. Supercars confirmed their engagement in June 2023.

The timing made the moment particularly personal. Rather than simply becoming another celebrity engagement announcement, it represented a new chapter for two people dealing with considerable grief together.

Riarne Marwood and Chaz Mostert’s Daughter

Riarne and Chaz welcomed their daughter Everly Rose Mostert on March 26, 2024.

Riarne announced Everly’s birth through social media, sharing the baby’s name and expressing how much the couple loved their new daughter. Her arrival came less than a year after the loss of Hazel.

Chaz later spoke about how fatherhood had changed his life away from racing. He described home life positively while balancing the demands of competing at the highest level of Australian motorsport.

Everly has understandably become an important part of the family’s story, although Riarne and Chaz have not turned their daughter’s everyday life into a constant public feature.

Riarne Marwood and Chaz Mostert’s Wedding

After years together and their 2023 engagement, Riarne Marwood officially became Chaz Mostert’s wife in December 2024.

The couple married near the Queensland and New South Wales border. People from the Supercars world attended, including champion driver Will Brown, while Cam Waters served as one of Mostert’s groomsmen.

Their wedding completed a remarkable year for the family. Everly had arrived in March, while Mostert was also enjoying a successful season professionally.

For fans who still find older articles referring to Riarne as Chaz Mostert’s girlfriend or fiancée, those descriptions are now outdated. The couple are married.

Riarne Marwood’s Height

Several celebrity biography websites list Riarne Marwood’s height at approximately 5 feet 6 inches, or 168 cm.

There does not appear to be a reliable primary or established motorsport source confirming that measurement, however. It is therefore better treated as a commonly reported estimate rather than an officially verified figure.

The same caution applies to several other physical and biographical statistics circulated about her online.

Riarne Marwood’s Net Worth

Riarne Marwood’s personal net worth has not been publicly disclosed.

Figures between $300,000 and $600,000 have appeared on celebrity biography websites, but there is no reliable financial documentation supporting a precise estimate.

Unlike Chaz, whose earnings are connected to a highly visible professional motorsport career, details about Riarne’s income, investments or business interests are mostly private.

Any exact net worth figure attached to her should therefore be viewed as an unofficial estimate rather than confirmed financial information.

Riarne Marwood on Instagram

Riarne has maintained a social media presence under the Instagram handle @riarne.m. Her account has previously been used to share major family updates, including Everly’s arrival, and has also provided occasional glimpses into her life with Chaz.

Social media has played an important role in how followers have learned about milestones in their relationship because the couple otherwise keeps large parts of their personal life fairly private.

Life With Chaz Mostert Today

Riarne Marwood’s public story is closely connected with motorsport, but there is more to her life than simply being introduced as Chaz Mostert’s wife.

She has been beside Mostert through championship battles, major victories, personal loss, engagement, parenthood and marriage. Their relationship has developed publicly over many years without becoming overly exposed.

Today, Riarne and Chaz are married and raising daughter Everly Rose while Mostert continues his professional racing career. For Riarne, public attention may have begun around motorsport events, but family life has increasingly become the part of her story that followers know best.
