Walk down the dairy aisle of your local Coles or Woolworths on the wrong week and you may find yourself staring at a gap where the yoghurt used to be. It is not a supply chain failure or a transport strike. Somewhere on TikTok or Instagram, a recipe went viral, and thousands of Australians decided they needed the same ingredient at roughly the same time.
That is the new reality facing Australia's major supermarkets, according to reporting by 9News. Social media trends are moving faster than restocking cycles, and the gap between a video going viral and a product selling out can be measured in hours rather than days.
Coles development chef and ambassador Michael Weldon has seen it firsthand. When the viral Japanese cheesecake trend swept social feeds, shoppers began buying yoghurt in volumes that caught even experienced buyers off guard. "The viral Japanese cheesecake has gone a bit crazy," Weldon said. "We've seen our yogurt sales go through the roof." Cottage cheese followed a similar arc, recording a 68 per cent sales increase in the first half of the financial year as home cooks experimented with high-protein recipes promoted across social platforms.
Not every trend is about culinary creativity. The Pascall Clinkers phenomenon last September had nothing to do with taste and everything to do with a guessing game: people promised to do something embarrassing or impressive if they correctly identified the colour of the Clinker before they bit into it. Clinkers sales doubled compared to the same period the previous year. "It's a constant battle for us to keep up with the trends because they're so fast-moving," Weldon said.
Both Coles and Woolworths have responded by investing in dedicated innovation kitchens staffed by teams whose sole focus is identifying what shoppers will want before the algorithm tells them to want it. Woolworths head of commercial rewards Jessica Loader described the approach plainly: "We have a team here who's concentrating on looking at what the next big thing is. They're working in our innovation kitchens, they're looking at trends in restaurants and around the world."
Weldon points to Coles' Shaker Salad range as a product born directly from online enthusiasm for the classic cucumber salad that swept feeds earlier this year. "Off the back of trends, we'll develop products to match those trends," he said. It is a significant shift in how consumer goods reach shelves: instead of producers leading demand, a teenager with a good camera and a willing audience can now move retail inventory at scale.
There is a legitimate consumer concern buried in all of this. When a product sells out because of a coordinated promotional campaign or an influencer partnership, shoppers who simply want their regular yoghurt or their usual packet of Clinkers are left empty-handed. The Australian Competition and Consumer Commission has previously flagged concerns about transparency in influencer marketing, and the question of whether supermarkets should be more upfront about trend-driven stock fluctuations is a reasonable one for regulators to consider.
From the supermarkets' perspective, the commercial logic is obvious. Viral demand is free advertising, and a product that trends online can shift more units in a week than a traditional promotional cycle achieves in a month. The Australian Bureau of Statistics retail trade data consistently shows that discretionary food spending is sensitive to cultural cues, and social media has become the most powerful cultural cue of all.
As for what comes next, Loader and Weldon are already watching closely. Fibre is tipped as the next nutritional trend to drive sales. Dumpling lasagna, apparently a thing, is gaining traction. And a genre Weldon is calling "swavoury", combining sweet and savoury flavours, may be the next unexpected shortage waiting to happen. Whether that excites or baffles you probably depends on how recently you last scrolled through a food-focused feed.
The broader picture here is one of supply chains adapting, sometimes clumsily, to a media environment that moves at a pace traditional retail was never designed to handle. Supermarkets are spending real money on innovation kitchens and trend-watching teams, costs that ultimately flow somewhere through the pricing structure. Whether that investment genuinely serves shoppers or primarily serves the bottom line is a question worth keeping in mind the next time a bare shelf greets you in the dairy aisle. Both things can be true at once: companies responding rationally to market signals, while ordinary consumers occasionally bear the inconvenience of a world where dinner ideas are decided by an algorithm.
