It's set to be the largest data centre project in Australia, but the Western Downs Digital Park (WDDP) has left many Australians with unanswered questions.

Park → set → questions
Artificial intelligence behemoth Anthropic has signed a long-term lease to run its Claude AI system out of the yet-to-be-built data centre in Queensland's Western Downs.
asserted
Anthropic → sign → Downs
Zerra DC, a developer based in Singapore, has forked out $30 billion to build the data centre, and it is expected to take four to six years to build the facility.
asserted
it → base → facility
Despite that, Anthropic plans to start using Building One at the centre in 2027.
asserted
Anthropic → plan → 2027
It's important to note that Anthropic's lease is subject to Foreign Investment Review Board approval.
asserted
lease → note → approval
Queensland Premier David Crisafulli says this data centre investment will drive down energy costs for consumers and bring jobs to the community.
But as Queensland opens the door to artificial intelligence, here's some things you should know about the proposed centre in Western Downs.
asserted
you → say → Downs
The site will be located on Dalby Kogan Road in the western Queensland suburb of Kogan.
asserted
site → locate → Kogan
How much water is it going to use?
asserted
it → go → water
The developers claim the data centre will be 100 per cent air cooled.
uncertain
centre → claim → ?
That would, in theory, result in far less water consumption than other data centres.
asserted
That → result → centres
Zerra DC said the first building, or Phase 1 of the project, will require 21,000 litres of water a day once fully operational.
asserted
building → say → water
Per year, that amounts to 7.7 million litres of water required for the first building.
asserted
that → amount → building
"That's nothing," Ian Wright, associate professor in environment science at Western Sydney University said.
asserted
Wright → say → University
He said that would be similar to the water consumption of a small shopping mall.
asserted
that → say → mall
"I would say that was a fraction of what I was expecting.
asserted
I → say → what
I expected it would need more like 21,000 litres in a matter of minutes."
For the entire campus of four buildings, Zerra DC estimates a total of 25.5 million litres of water would be required per year once fully operational.
asserted
total → expect → year
Zerra DC says the data centre will also meet 40 per cent of its daily water demands through "on-site water recycling" which it claims will bring the actual outside water requirement down to around 13,000 litres a day.
uncertain
it → say → litres
It says that will be met by rainwater harvesting and the facility will not use groundwater for operations.
asserted
facility → say → operations
However, it will be able to draw on groundwater as a last-resort contingency, according to the developer.
uncertain
it → draw → developer
How does air cooling help?
asserted
cooling → help → ?
The air-cooling set-up for this facility will use a heat-rejection system that uses closed-loop water circulation within the data centre, but heat is rejected to the outside air rather than through evaporation.
asserted
heat → use → evaporation
Mr Wright said if the system works, it would be "brilliant", but he had concerns.
asserted
he → say → concerns
"That would be a game changer and that goes against my knowledge of what happens around the world," he said.
"
asserted
he → go → world
I suppose there's a dubious edge to my voice here — it just sounds too good to be true."
asserted
it → suppose → voice
This system has been successfully used in other data centres, however usually on a much smaller scale as they have been known to struggle with high-density server racks, which are common in AI workloads.
asserted
which → use → workloads
"It looks like they've done their homework," Mr Wright said.
asserted
Wright → look → homework
I reckon the world will be watching to see if you could build something this big air cooled."
uncertain
you → reckon → something
According to Zerra DC, the data centre is expected to provide around 1,400 jobs directly at the facility once fully operational.
uncertain
centre → accord → facility
It says those ongoing roles will lie in mechanical, electrical, controls, security and ICT information, as well as communications technology which covers computing, telecommunications, networks, software and related digital systems.
asserted
which → say → computing
A report from the UK government found that while data centres require a lot of staff to build, the number of daily jobs created for operations is "relatively modest" and is likely only ever a few hundred.
asserted
number → find → operations
The Virginia state government in the US found that a 23,226 square metres (sqm) data centre "may have approximately 50 full-time workers".
uncertain
centre → find → workers
The facility in Western Downs will utilise approximately 195,000sqm of total floor space once fully built and the sheer size is one reason for the greater need for staff
asserted
size → utilise → staff
, the developers said.
asserted
developers → say → ?
While the facility is being built, the developer says a further 1,500 on-site construction workers will be required, with indirect jobs also expected to arise both during construction and ongoing at the facility.
asserted
jobs → build → facility
In the proposal for the development, Zerra DC said the digital park will "connect directly to the high-voltage transmission network at the existing Braemar substation".
asserted
park → say → substation
The infrastructure required for the connection and the connection process itself would be provided and organised by the tenants of each building, Zerra DC said.
asserted
DC → require → building
The AI giant plans to go to market for long-term power purchase agreements with renewable energy suppliers.
asserted
giant → plan → suppliers
The data centre would have a peak electrical capacity of 2.16 GW.
asserted
centre → have → GW
Electro-mechanical engineer Dr Andreas Helwig said that is extremely large by Australian standards.
"If fully built out and operating at typical hyperscale utilisation, it would draw around 43–47 gigawatt-hours (GWh) of energy per day," he said.
asserted
he → say → day
He added that is roughly 25–30 per cent of Queensland’s entire average daily electricity consumption.
asserted
that → add → consumption
