Australian Fast-Food Stocks Slump as Cost-of-Living Pressures Erode Discretionary Spending

Major Australian fast-food operators are facing a significant market correction as a prolonged cost-of-living crisis reshapes consumer behavior across the country. Shares in industry heavyweights, including Domino’s Pizza Enterprises (ASX: DMP) and KFC operator Collins Foods (ASX: CKF), have experienced double-digit declines on the Australian Securities Exchange (ASX), reflecting investor anxiety over the durability of discretionary spending.

The downturn comes as Australian households grapple with a combination of high inflation, elevated interest rates, and surging transport costs. According to recent data, Australia’s annual inflation rate jumped to 4.6% in March 2026, marking its highest reading since September 2023. This inflationary spike has been heavily influenced by transport costs, which rose 8.9% over the same period, driven by volatility in global energy markets.

Domino’s Faces Global and Local Headwinds

Domino’s Pizza Enterprises has been among the hardest hit in the sector. As of April 28, 2026, the company’s shares were down approximately 25% year-to-date and have plummeted 38% over the past 12 months. A single trading session in April saw the stock tumble 11% following underwhelming financial results from its United States counterpart, which heightened fears regarding global consumer resilience.

The company’s struggles are not limited to the Australian market. In the first eight weeks of the second half of the 2026 financial year, Domino’s reported a 7.2% drop in same-store sales across Germany and the Netherlands. Globally, like-for-like sales declined by 3% in the first half of FY26.

Domino’s has also faced criticism over its value proposition. An analysis from August 2025 highlighted a significant erosion in the value of the company’s flagship $5 pizza, noting that since 2016, the product has effectively become more expensive for consumers through a combination of price increases and smaller portion sizes. As households tighten their belts, the traditional perception of fast food as an affordable luxury is being challenged.

The 'Trading Down' Paradox at Collins Foods

Collins Foods, the operator of KFC and Taco Bell outlets in Australia, presents a more nuanced picture. While the company reported a 6.6% lift in full-year revenue for its KFC Australia operations in June 2024, its share price still fell 25% in the calendar year leading up to that report.

Market analysts attribute this disconnect to the "trading down" effect. In high-inflation environments, some consumers opt for fast food as a cheaper alternative to full-service restaurant dining. However, even this momentum appears to be slowing. In the first seven weeks of FY25, KFC Australia’s same-store sales were down 0.8%, partially impacted by the cannibalisation of sales from new restaurant openings.

Investors remain cautious, as the broader economic data suggests that even the "trading down" buffer may not be enough to offset the sustained erosion of household purchasing power. Real GDP per capita in Australia fell for seven consecutive quarters throughout 2023 and 2024, a trend that makes the Australian economy a notable outlier among developed nations.
