Stacked Farm's A$150M Robotic Greenhouse Opens in Melbourne as Vertical Farming Faces Its Reckoning

Stacked Farm, the Australian agritech company founded on the Gold Coast in 2016, is about to switch on the largest machine it has ever built: a A$150 million vertical farm in the Melbourne Airport precinct, scheduled to open in the fourth quarter of 2026. The 10,000-square-metre facility, fully enclosed and climate-controlled, is projected to produce 3.4 million kilograms of leafy greens and herbs a year, harvested every week of the year without ever opening a door to the weather outside.

The Melbourne opening is only half the announcement. The company has begun raising A$45 million in working capital to fund its next phase: a US$126 million production farm in Southern California, a research and customer experience centre that opened in Las Vegas in September, and a stated plan to build 10 farms across major American markets within five years. Financing for the California facility is nearing completion and is expected to rest on long-term supply agreements with major West Coast wholesalers, though Stacked Farm has not given an opening date for the American farm.

It is a credibility test for an industry that has spent a decade promising to reinvent agriculture while some of its most celebrated names collapsed under the weight of their own economics. Founder Daniel Tzvetkoff says the company deliberately spent years refining its automation platform, operating model and unit economics before attempting international growth, with an emphasis on consistent output, customer demand and long-term profitability. As he puts it, the industry has proved it can grow great produce; its remaining challenge is proving it can do so reliably, repeatedly and economically at commercial scale.

A farm run by 25 robots and 15 people

The Melbourne operation moves produce from seed to sealed packaging without direct human handling, using robotics, artificial intelligence and automated crop management. Digital traceability follows product through every stage of the process, a design intended to keep output consistent and cut contamination risk. The entire 10,000-square-metre plant is designed to run with just 15 staff alongside 25 proprietary robots, a staffing ratio that would be unthinkable in a field operation of comparable output.

The company claims dramatically compressed crop cycles: greens ready in 16 to 31 days, compared with 45 to 80 days for conventional growing, according to its original project announcement. The facility is designed to run on green energy with a zero-waste water system, and it will specialize in cos, mixed leaf lettuces, spinach, rocket and basil, crops whose economics work indoors. By shielding production from adverse weather, the company says the farm can cut reliance on imported produce and deliver quality that does not change with the season.

Why Australia first, then America

Stacked Farm's strategy is to prove the model at home before exporting it. The Melbourne facility is described as the most advanced deployment of its platform to date and the operational blueprint for every site that follows. Validating the technology in Australia, where energy costs and distance from major markets are genuine constraints, gives the company a working proof to sell to American partners. The airport precinct location is itself a statement: the farm is the first large-scale vertical farm in an airport precinct in the Southern Hemisphere, putting fresh greens within minutes of freight and distribution channels.

The American push is already underway. The Las Vegas hub, opened in September 2026, serves as a research and customer experience centre. The Southern California farm, budgeted at US$126 million, is expected to operate under long-term supply agreements with major West Coast wholesalers, a detail that matters more than any rendering of the building. Offtake contracts give financiers and retailers numbers they can plan around, and they are the difference between a speculative facility and a financed one. "Expanding into the U.S. allows Stacked Farm to deliver the same reliability, quality, and scale we are building in Australia to millions of American consumers," Tzvetkoff said.

The five-year target is 10 farms across major American markets, each replicating the automated system. It is ambitious, but the money behind it is not the usual hype-cycle capital: the Melbourne project drew investment from Magnetar Capital, a US-based alternative assets manager, and the company's slow-build approach stands in deliberate contrast to the grow-fast-first, figure-out-economics-later playbook that burned earlier vertical farming operators.

The economics question still stands

The pitch for vertical farming has always been seductive: climate-resilient, land-saving, water-efficient, with production next door to the customer. The rebuttal comes down to a single word: energy. Replacing free sunlight with LED rigs, HVAC systems and computerized infrastructure turns food into an energy-intensive manufactured product, as geographers at Western University argued in a widely discussed critique published this month. Governments keep betting regardless: Canada's first-ever National Food Security Strategy, launched in June 2026, commits $750 million to year-round domestic production of fruits and vegetables, including vertical farms.

Stacked Farm's answer is automation density: fewer hands, faster cycles, predictable output, contracted demand. Whether the numbers work will be visible soon enough. The Melbourne plant's commissioning in the fourth quarter of 2026 is the first public test of whether a decade of patient engineering can do what a wave of venture-funded hype could not. If the economics hold, the California build becomes the real experiment: can an Australian automation stack win shelf space in American produce aisles against conventional field-grown supply chains? For now, the company has not set a California opening date, and the A$45 million raise still has to land. The industry will be watching. This time, there will be receipts to show.
