Australia's data centre sector is confronting a credibility crisis triggered by community resistance. Beneath the AI infrastructure investment boom, a "triple bottleneck" of land, capital and power permits is dragging lofty growth narratives back to reality.
The "Australian version of CoreWeave" and a bellwether for AI infrastructure, NEXTDC LTD (ASX: NXT), disclosed on Wednesday that due to persistent obstruction by inner-Melbourne residents against high-voltage transmission line construction, power supply for its key M3 project has been pushed back to FY2028, forcing the company to slash its FY2027 earnings guidance by more than one-third. The company also announced a halt to all new development projects and land acquisitions, and is assessing whether force majeure provisions can be invoked on affected contracts.
Following the announcement, NEXTDC shares plunged as much as 45% to A$5.07 after a two-day trading halt on the Sydney market, falling back to 2019 levels and dragging down local peers across the board.
This incident further confirms the delivery predicament facing the global data centre industry 鈥?GPUs are in place and customer contracts are signed, yet what truly stalls projects are grid connection permits and opposition from nearby residents. According to Bloomberg, in the first half of this year alone, at least 106 data centre projects in the United States were blocked or delayed due to community opposition, involving approximately US$198 billion in investment.
Excavators Turned Back by Residents: The "Low-Tech" Collapse of the M3 Project
The trigger for NEXTDC's share price collapse was a rather dramatic scene of community confrontation.
To supply power to the M3 project, grid operator Jemena Electricity Networks needed to erect high-voltage transmission poles along residential streets in Maribyrnong, an inner-western suburb of Melbourne. In September this year, local residents used private cars to block construction vehicles and refilled excavated trenches. Jemena subsequently suspended work citing "safety concerns and obstructed site access," stating that resumption before February 2027 was unlikely at the earliest. M3's next grid capacity upgrade has therefore slipped into FY2028.
The local council is still awaiting further community consultation before granting planning approval, and planning decisions for M3 phases six and seven have been pushed to 2027 鈥?precisely crossing the point at which the Victorian state government enters caretaker mode ahead of the November 28 election.
The financial impact on NEXTDC was swift. According to documents filed with the ASX: FY2027 net revenue guidance was cut from A$615 million鈥?A$640 million to A$475 million鈥?A$500 million; FY2027 underlying EBITDA guidance was reduced from A$385 million鈥?A$410 million to A$245 million鈥?A$265 million, a median decline of approximately 36%; FY2027 capital expenditure guidance was narrowed from A$5.25 billion鈥?A$5.75 billion to A$4.5 billion鈥?A$5.0 billion.
The new guidance excludes approximately A$140 million in revenue and EBITDA related to affected M3 contracts, including some capacity that had already begun billing. The company also warned that EBITDA could come under further pressure if service-level penalty payments to customers are required. CEO Craig Scroggie said on an investor call:
"We will not proceed with any work at any site without existing customer commitments."
Goldman Sachs Warned Early, Capital Remains the "Handbrake"
Just eight days before the plunge, Goldman Sachs analyst Chris Boulus's team published a major report covering Australia-New Zealand digital infrastructure, forecasting that ANZ IT load demand would expand to 5.2GW by 2030, with a supply-demand gap of 0.7GW at that time, and characterised the overall data centre capital expenditure cycle at A$50 billion to A$65 billion.
Notably, Goldman Sachs had already assigned a cautious rating to NEXTDC in the same report. At the time, Goldman initiated coverage on Goodman Group and Megaport with "buy" ratings, but only initiated NEXTDC with a "neutral" rating and a A$11 price target, reasoning that "the market loves the macro demand narrative, but capital is the real handbrake." The report set NEXTDC's FY2028/2029 EBITDA forecasts 3% to 5% below market consensus and flagged a potential funding gap of more than A$1 billion, asking whether "de-risking capital joint ventures" or "potential dilutive equity raising" would be the path forward.
Currently, NEXTDC still holds A$8.7 billion in liquidity on its balance sheet, including A$6.7 billion in undrawn senior debt, and the company says it remains in compliance with covenants. However, the company also warned in its filing that if billings configuration changes materially 鈥?such as the revenue shortfall caused by the M3 delay 鈥?it could limit its ability to draw on that senior debt. According to Market Index citing UBS forecasts, NEXTDC is not expected to achieve profitability until FY2031 at the earliest, with long-term debt peaking at A$11.2 billion in FY2030. At the current share price, NEXTDC trades at approximately 37 times FY2027 EV/EBITDA, while according to Goldman Sachs data, the global average valuation for pure-play data centre operators is 22 times 鈥?and this comparison does not yet factor in the latest A$1.1 billion convertible notes. Market Index therefore noted that NEXTDC "even after another 40% decline, would merely be returning to global peer valuation levels."
"Force Majeure" Is Becoming a New Buzzword in the Data Centre Industry
NEXTDC's invocation of force majeure provisions is not an isolated case.
On September 24 this year, Oracle issued a force majeure notice for its large "Project Jupiter" campus in New Mexico, also due to permitting delays and obstructed power access, after which it emerged that the company had to transport natural gas to the data centre to maintain operations. In early October, Finnish authorities ordered Google to suspend construction on two data centres. Now, the same scenario is unfolding again in Melbourne.
According to Bloomberg, Morgan Stanley previously estimated that in 2025 alone, US$156 billion in data centre projects globally had been cancelled or delayed, with that figure reaching a further US$130 billion in the first quarter of 2026. Texas has directly ordered a halt to new data centre construction.
RBC stated unequivocally that the M3 delay is strong evidence that "community opposition poses a real risk to the delivery timeline of contracted data centre capacity." Mark Luet, head of investment banking for Japan, North Asia and Australia at Citibank, said in an interview with Bloomberg Television that investors will be "more discriminating" going forward, while adding: "We have no doubt whatsoever that the AI infrastructure theme will continue to advance."
Self-Generated Power, or No Way In
In industry circles, the fundamental solution to the grid connection dilemma is seen as "self-generated power." The Australian government issued a mandatory national rule in July this year requiring data centre operators to "fully self-fund their power needs and provide guarantees for new generation projects."
Goldman Sachs also adjusted its forecasts in its Carbonomics report, with analyst Michele Della Vigna raising the global data centre "behind-the-meter" power supply forecast to 67GW by 2030, at which point on-site gas turbines, reciprocating engines and fuel cells will meet 25% of global data centre power demand 鈥?a share that was "virtually zero" in 2025. The logic behind this: grid connection waiting times have extended from historically about two years to more than seven years today, while data centres themselves take only two to three years to build.
The M3 project is precisely a microcosm of this contradiction: the building shell is largely complete, customer contracts are in hand, and the only thing missing is a 66kV grid capacity upgrade line 鈥?a line blocked on the street by a few private cars and a few shovels.
Meanwhile, Reserve Bank of Australia Deputy Governor Andrew Hauser recently listed the "data centre construction boom" as one of the three upside risks to Australian inflation, prompting Goldman Sachs Australia economists to revise their previous rate-pause expectations and instead forecast an RBA rate hike of 25 basis points to 4.85% in November. This means: the data centre investment boom is raising the data centre industry's own financing costs 鈥?an unideal feedback loop for an industry that Goldman Sachs had already identified as having "capital as its biggest constraint."
NEXTDC's board will release the results of its capital expenditure review at its annual general meeting on November 20, when the question of whether "selling development land not needed in the near term" will mark the start of a series of asset sales deserves close market attention.
