The reality show Married At First Sight (MAFS) Australia continues to deliver its signature drama, with Teejay Halkias, an intruder groom on the 2025 season, attracting quite a bit of attention. Before his appearance on MAFS, Teejay was no stranger to television, having participated in Big Brother Australia in 2023.

Recently, unearthed footage from his past has fans raising concerns, spotting what many describe as a “major red flag” in his behavior. Teejay’s been matched with Beth Kelly, a charming and relatively unseasoned bride from the UK, and his previous television stint has sparked curiosity about whether his past could spell trouble for their marriage. Let’s delve into what has everyone talking.

Teejay is not new to the reality TV scene. He joined Big Brother Australia as an intruder in 2023, entering the show midway through the season and lasting until the ninth elimination. Originally from Adelaide and currently residing in Queensland, this 28-year-old business development manager comes from a large Greek-Indian family and is the youngest of seven siblings yet to marry.

On Big Brother, he was portrayed as a charming, sociable guy—traits that probably caught the attention of MAFS producers.

However, a specific moment from that show, which fans have recently resurfaced, is raising questions about his character. During a game of Truth or Dare, Teejay reacted defensively when asked about his number of sexual partners, a reaction that some viewers now find concerning given his presence on MAFS.

So, what’s the big deal here? In that Big Brother clip, Teejay’s discomfort with the “body count” question stood out. He didn’t just evade it—he appeared annoyed and almost defensive, leading fans to speculate about his views on relationships and intimacy.

Fast forward to MAFS, where he’s matched with Beth, a 28-year-old salon manager who has never had a boyfriend. The difference between them is striking: while Beth is a novice in the romance department, Teejay seems to have a more complex past.

Fans on X have labeled this a red flag, with comments like,

“The producers knew this and still paired him with Beth—poor girl,”

suggesting he may not be the steady, supportive partner she needs. Others argue that it’s not just about his number of partners but more about his reluctance to open up, signaling potential trust issues.

On MAFS, Teejay and Beth clicked right away. Their wedding felt refreshing compared to the chaos of other pairs, with Teejay expressing to producers,

“She’s beautiful… I definitely felt a spark.”

Beth, anxious about her lack of dating experience, was relieved by Teejay’s respectful reply:

“Hopefully we can change that.”

Their chemistry continued through the honeymoon, making them one of the more stable couples this season.

However, cracks began to show during Homestay Week, when Teejay confessed he wasn’t sure if their relationship would survive beyond the experiment, even after they’d been intimate. Beth felt blindsided, and fans began to connect this back to his Big Brother moment—could his guarded demeanor point to deeper commitment issues?

The online reaction has been pretty heated. Some viewers consider Teejay’s past on reality TV to be a red flag, with one post on X stating,

“He’s a f—boy paired with an innocent girl—MAFS really messed up.”

Others are defending him, arguing that one clip doesn’t define someone, and pointing to his actions on MAFS—like standing up for Beth when another groom called her “classless”—as signs of a caring personality.

Opinions are divided, but it’s clear that his Big Brother appearance has placed an extra layer of scrutiny on him. For Beth, who’s new to all this, it’s a lot to handle. As the season goes on, whether this “red flag” proves to be significant or fades into the background will depend on how Teejay navigates the pressure—and how much Beth is willing to overlook.
