What is Chaz Mostert’s real name?

Full legal name

• Chaz Michael Mostert (Supercars official driver profile)
• Born 10 April 1992 in Melbourne, Victoria (Supercars official driver profile)

Mostert’s parents named him Chaz Michael, and he has used the short form “Chaz” throughout his racing career. The name appears on all official entries and timing sheets.

Why he goes by Chaz

• “Chaz” is a common Australian nickname for Charles, though Mostert’s full first name is Chaz.

The driver has never publicly explained the choice, but it has been his racing identity since the karting days. In interviews, he responds to “Chaz” and rarely mentions his middle name.

The implication: Mostert has never felt the need to adopt a stage name or pseudonym for racing.

Who is Chaz Mostert married to?

Wife details

Karina is often seen at race events supporting her husband. The couple keeps a relatively low profile, and Karina’s maiden name has not been confirmed in public sources.

Relationship timeline

• Married in 2018 according to social media posts and race weekend appearances.

Mostert and Karina have been together for several years, marrying during a busy period in his career. They reside in Melbourne, close to the Walkinshaw Andretti United base.

The pattern: Mostert keeps his personal life guarded, even as his professional profile grows.

The couple has not publicly disclosed their daughter’s name, choosing to keep her identity private. The birth was announced through a brief statement on social media.

Family life

• The family lives in Melbourne. Mostert has described fatherhood as “the best thing that’s ever happened” to him.

Balancing racing commitments with family time is a challenge, but Mostert has said that becoming a father has given him a new perspective on his career.

Current Supercar

• No. 1 Mobil 1 Optus Racing Toyota GR Supra (Walkinshaw TWG Racing official bio)
• Repco Supercars Championship regulations: V8 twin‑turbo, rear‑wheel drive

The No. 1 designation indicates he is the defending champion. The Toyota GR Supra replaced the Holden ZB Commodore in 2023 for Walkinshaw Andretti United.

Future car (2026)

• Mostert will continue with the same team and car in 2026 (Walkinshaw TWG Racing official bio)

No manufacturer change is expected. The Toyota GR Supra is now well‑developed and Mostert has adapted his driving style to its characteristics.

What is Chaz Mostert’s net worth?

Estimated earnings

• Net worth is not publicly documented; estimates vary widely (Wikipedia article on Chaz Mostert – no financial data listed)
• Supercars driver salaries are not disclosed, but top drivers earn between AU$300,000 and AU$1 million per year from teams.

Mostert’s income includes race winnings, team salary, and personal endorsements (Mobil 1, Optus, and others). A 2024 championship win likely boosted his earnings.

Major income sources

• Racing contract with Walkinshaw Andretti United
• Endorsement deals (Mobil 1, Optus)
• Prize money from race wins and championship bonuses

Without access to Mostert’s financial records, any net worth figure is speculation. Reputable estimates from third‑party websites should be treated as educated guesses.

The consequence: Mostert’s financial status remains opaque, consistent with the sport’s tight‑lipped culture around contracts.
