When Sarah Czarnuch, the long-time partner of Marcus Stoinis, mouthed the F-word after Punjab Kings’ top-order collapsed in the IPL 2025 Qualifier 1 against RCB, it wasn’t just a reaction; it was the rawness of emotion cricket so often unleashes.

Stoinis, dismissed by Suyash Sharma when the team desperately needed him, was the only glimmer of hope in a bleak 101-run innings. Beyond that viral moment, Czarnuch is a 27-year-old Australian model, entrepreneur, and fitness enthusiast with a strong online presence and a growing fashion label, SarahCzarnuch X Elliatt.

The couple, reportedly dating since March 2021, often shares affectionate glimpses online.

Who Is Sarah Czarnuch?

Czarnuch is far more than just a familiar face in the stands. A winner of the Miss Tourism Metropolitan International crown back in 2013, she has since evolved into a sought-after model and creative entrepreneur. Her clothing label SarahCzarnuch X Elliatt is a reflection of her aesthetic and business drive. Known in Australia for her distinct personal style, Czarnuch is also a content creator who takes her fitness seriously. Her Instagram profile (@sarah_czarnuch), with over 129k followers, showcases everything from fashion and design to candid moments with Stoinis.

Relationship Timeline: From Posts to Nicknames

Stoinis and Czarnuch have reportedly been together since March 2021. Their social media presence is sprinkled with cozy selfies, birthday tributes, travel moments, and light-hearted banter. Stoinis once referred to them as “Stoinah” in a post, while Czarnuch suggested “Sarcus” in a cheeky comment. Their relationship doesn’t chase the limelight, but it remains visible enough to show real affection and mutual admiration.

Stoinis publicly celebrated Czarnuch’s 27th birthday on December 7, 2023, with a heartfelt post calling her “bestie”. Their dynamic seems rooted in comfort and shared values rather than performance for the public eye.

Past Ties: The Stephanie Muller Chapter

Before Czarnuch, Stoinis was reportedly in a long-standing relationship with Stephanie Muller. They went public around 2013 and were often seen at events together. It appeared serious — to the point of wedding speculations — until everything came to a quiet halt in 2021. No official statement explained the breakup, but the complete deletion of shared photos by Stoinis hinted at a definitive close to that chapter.

Rumors and Realities: What About Adam Zampa?

Much internet chatter has speculated about the close bond between Stoinis and teammate Adam Zampa. Their camaraderie and humor during tours sparked plenty of talk, but nothing romantic lies beneath. Zampa tied the knot with his long-time partner Hattie in 2021, and fans eventually understood the duo’s interactions for what they were — an unfiltered, genuine friendship, not a love story.

Czarnuch’s reaction during the qualifier was honest and unpolished, reminding everyone that behind the athletes and the glamour are real people, and raw responses. Whether it’s her growing business, her vibrant social presence, or her supportive partnership with Stoinis, Czarnuch stands firmly in her own light not just as someone in the background, but as someone with a story worth knowing.
