TikTok Creator Undiagnosed Anthony Becomes Face of Swisse's Sweet Treat Campaign

I'll try everything. That's just who I am.
Voulgaris explains his approach to food and why he doesn't limit himself to one flavour or type of treat.

In the quiet evolution of online food culture, a Melbourne creator who once sat in cars rating burgers found himself unexpectedly crowned the internet's authority on sweetness. Anthony Voulgaris — Undiagnosed Anthony — built a million-follower following not through strategy but through honest contradiction: a self-declared savoury person who couldn't stop talking about desserts. Swisse, recognising something more durable than influence, offered him a role that required no performance — only the genuine enthusiasm he'd already been giving away for free.

  • A content creator built on fast food credibility found his identity quietly hijacked by gummies, gelato, and the pull of the sweet side.
  • The tension between his savoury self-image and his dessert-obsessed content turned out to be the most compelling thing about him — audiences leaned in precisely because it felt unplanned.
  • Swisse had to intervene on set to stop him exceeding the recommended daily gummy intake, a moment that accidentally became the campaign's most convincing proof of authenticity.
  • A Gold Coast ice-cream truck distributing over three thousand free scoops translated a supplement brand into a street-level sweet treat experience that felt nothing like an advertisement.
  • On May 25, a Swan Street mural in Richmond will fix his image into the city's landscape — the food reviewer who became the thing people review.

Anthony Voulgaris didn't plan to become the internet's dessert authority. The Melbourne creator known as Undiagnosed Anthony built his TikTok following the familiar way — in-car dining videos, fast food verdicts, the honest question of whether something was worth the hype. He identified as a savoury person. Then, almost accidentally, the sweet treat videos started.

The contradiction was the point. A self-described savoury enthusiast becoming quietly obsessed with desserts turned out to be exactly what his audience wanted to watch. The occasional aside became a signature series, and a million followers came along for the ride.

Swisse noticed something more useful than reach — they noticed he already loved their gummies. When they brought him on as official 'quality taste assurance manager', the shoot had to be paused because he kept eating past the recommended daily amount. His personal favourite, the Apple Cider Vinegar and Fibre Gummies, reveals the specificity that makes him credible: he doesn't endorse everything equally. He has actual preferences.

The campaign built around him reflects the same logic. The Sweet Treat Club reimagined the gummies as limited-edition gelato flavours — baked apple and cinnamon cake, Sicilian orange and berries — and an ice-cream truck on the Gold Coast handed out more than three thousand free scoops in early May. It worked because it didn't feel like advertising. It felt like someone sharing something he'd genuinely discovered.

The story lands on May 25, when a mural goes up on Swan Street in Richmond — Voulgaris painted large, surrounded by oversized gummies, crowned king of sweet treats. The food reviewer who once asked what was worth lining up for has become the face that answers the question.

Anthony Voulgaris didn't set out to become the internet's arbiter of desserts. The Melbourne content creator, known online as Undiagnosed Anthony, built his million-strong TikTok following the way most food creators do: by sitting in cars, eating things, and telling people whether the hype was justified. His early videos focused on the obvious targets—fast food joints, fried chicken spots, the usual suspects of Foodtok. But somewhere along the way, something unexpected happened. The savoury person, the one who'd built his reputation on chasing down the best burger or crispiest wing, started making videos about sweet treats instead.

It wasn't a calculated pivot. "When I started the sweet treat videos, the whole point behind it was that I am such a savoury person," Voulgaris explains. That contradiction—a self-described savoury enthusiast becoming obsessed with desserts—turned out to be exactly what his audience wanted to watch. The occasional aside became a defining series. What began as a curiosity morphed into his signature move.

Swisse noticed. The vitamin and supplement company approached him about becoming the official "quality taste assurance manager" for their gummies range, a title that sounds absurd until you realize Voulgaris wasn't being hired to pretend. He already loved the product. During the shoot, the company had to physically stop him from eating more than the recommended daily amount. "I forgot that there's a recommended amount you should be having a day," he says, laughing at himself. The partnership felt inevitable because it was genuine—no performance required.

What draws him to any dessert, he says, is the same thing that drives his content: something recognizable enough to understand, but with enough of a twist to stay interesting. His personal favourite from the range is the Apple Cider Vinegar and Fibre Gummies, which lean slightly tart. "I loved the smell of it and I love chewing it," he says. "I think I must just love apple cider vinegar." It's the kind of specific, slightly odd preference that makes him credible—he's not endorsing everything equally. He has actual tastes.

The campaign itself reflects that same philosophy. Swisse created the Sweet Treat Club, a limited-edition gelato concept that reimagined the gummies as ice-cream flavours. In early May, an ice-cream truck rolled onto the Gold Coast and handed out more than three thousand free scoops. The flavours—baked apple and cinnamon cake, Sicilian orange and berries—were inspired directly by the gummies range. It's the kind of activation that works because it doesn't feel like an ad. It feels like someone who genuinely loves dessert decided to share something he'd discovered.

The full-circle moment arrives on May 25, when a mural launches on Swan Street in Richmond. Voulgaris is painted larger than life, crowned as the self-appointed "king of sweet treats," surrounded by oversized gummies and delivering his seal of approval. A year ago, he was the person hunting down what was worth the hype. Now he's become the thing people hunt for—the face that signals something's worth trying. "You know how some people will be like, 'I only have pistachio ice-cream'?" he says. "Yeah, that's not me. I'll try everything." That willingness to taste anything, to find the interesting angle in the ordinary, is what turned a food reviewer into a brand. And it's what makes the partnership feel less like a transaction and more like a natural conclusion to a story that started with a simple question: what's actually worth lining up for?

How does someone who identifies as a savoury person end up becoming known for sweet treats?

Model

It wasn't intentional. I started making one video about a dessert I'd been enjoying, and people responded to it. The contradiction itself became interesting—the fact that I wasn't naturally drawn to sweets made it feel more honest when I said something was actually good.

Inventor

And Swisse saw that and thought, this is our person?

Model

They did, but it worked because I already used their gummies. I wasn't being asked to fake enthusiasm. On the shoot, I had to be stopped from eating too many. That's not an act.

Inventor

What is it about the Apple Cider Vinegar gummies specifically that appeals to you?

Model

They're tart. They hit that savoury note I'm naturally drawn to, even though they're technically a sweet product. It's familiar but unexpected—which is exactly what I look for in anything I review.

Inventor

Three thousand free scoops on the Gold Coast. That's a lot of people tasting your endorsement in physical form.

Model

It's surreal. The gelato truck made the gummies feel like an experience rather than a supplement. People lined up for something that didn't exist a month before, because they trusted the recommendation.

Inventor

And now there's a mural with your face on it.

Model

It's strange to see yourself painted that large, honestly. But it makes sense—I went from finding what was worth the hype to becoming the thing people trust to tell them what's worth the hype.
