Residents rallied in Mannum on Saturday against Quantum DC's proposed 1,200-megawatt data center at Tungkillo, about 41 kilometers east of Adelaide, on a 120-hectare site that would include a gas-fired power station.
No development application has been lodged, and Quantum DC has pushed its community consultations to November 20th and 21st, citing safety concerns.
"We will fight it using every legal means possible," organizer Magdalene Lippett said.
South Australia's planning minister said any application would have to meet power and water requirements.
The Greens want a moratorium; the Liberal upper-house leader said her party is "not against data centres."
Two Australian states produced organized opposition to data centers on consecutive days.
