A DECLASSIFIED AUSTRALIA SPECIAL INVESTIGATION – Part Two
It hasn’t received final approval yet, but already the company behind a proposed Central Australian toxic waste dump is bragging that the dump will take nuclear waste from “our strategic international partners”.
The company, Tellus Holdings, was revealed a month ago in Declassified Australia to be working with Amentum, a controversial US military contractor, to develop what had originally been described as a “salt mine” into a massive underground nuclear waste dump.
Tellus now says it envisions the Chandler salt mine and waste dump to be “the world’s first multinational deep geological repository for hazardous chemical and low-level nuclear waste”.
The nuclear waste dump, Tellus tells us, will take “international low-level radioactive waste [from] our strategic international partners”.
Tellus Holdings already operates Australia’s first geological repository for low-level radioactive waste at Sandy Ridge, 240 kilometres northwest of Kalgoorlie, which became operational in 2021.
Now, with advice from one of the US’s largest military contractors – which also manages a 400-strong workforce in Alice Springs providing support services to the US’s Pine Gap satellite surveillance base – Tellus is confident that its proposed waste dump will become a reality.
No approval for nuclear waste, at first
Tellus’s proposed Chandler Project received approval in 2017 for its environmental impact assessment (EIA) by the Northern Territory Environmental Protection Authority.
The EIA included approval for the permanent storage of so-called Naturally Occurring Radioactive Materials (NORM) up to exemption levels – the lowest level on the National Directory for Radiation Protection’s waste classification scheme.
NORM results from activities such as burning coal, making and using fertilisers, oil and gas production, and mineral sands and uranium mining.
The facility does not have approval to store any other forms of radioactive waste.
Despite this, Tellus has consistently described the prospective facility as approved to accept low-level radioactive waste; a category of radioactive waste that is well above the NORM exemption levels in Australia’s waste classification scheme.

The Northern Territory EPA’s assessment report describes the project components as including construction of an underground salt mine at a depth of up to 860 metres, permanent hazardous waste disposal vaults within mined-out salt caverns, temporary above-ground storage facilities for hazardous waste, and associated infrastructure like haul roads, access roads, and salt stockpiles.
From ‘no nuclear waste’ to nuclear waste ‘permission’
In its submission to the NT Environmental Protection Authority on the Chandler Project’s EIA, the Central Land Council (CLC), a statutory body under the Aboriginal Land Rights Act responsible for representing Aboriginal people in Central Australia, made clear the concerns of native title holders about the Chandler Project:
“Native title claimants have consistently expressed concern to the CLC about dangerous, poisonous and toxic waste being destined for permanent storage on their country and the issue of radioactive and nuclear waste has been raised at every meeting with the company.
“The company has repeatedly and consistently dealt with this concern by confirming that radioactive and nuclear waste will not be accepted at the repository”.
In 2021, Tellus made fanfare of voluntarily choosing to shelve its ‘major project status’ designation with the Northern Territory government in order to not pre-empt negotiations with native title holders.
By 2023, there had been a change to what materials the waste dump would be taking and what materials the traditional owners would now be accepting on their land.
In November 2023 after a decade of on-and-off consultation and two years after Tellus CEO Nate Smith described negotiations as “a bit stuck”, the company obtained permission from Southern Arrernte Traditional Owners for the construction of the Chandler nuclear waste dump on their Country.
Traditional owners entered into an agreement with Tellus as native title holders under the Native Title Act 1993. Under the Act, native title holders do not have veto rights over projects such as Chandler, but instead have the mere right to negotiate the terms of an agreement upon which the project may proceed.
Native title holders entered into an agreement under circumstances where the median weekly personal income in Titjikala is just $273, compared to $936 for the NT as a whole, and where successive racist government policies such as compulsory income management make many Indigenous communities heavily dependent on mining royalties.
There are a number of approvals and licences for the facility which remain outstanding, including its principal tenure Mineral Lease 30612. A final investment decision to allow the waste dump to proceed may still be years away.
Gaining trust through ‘disruption’
Tellus Holdings claims to have cracked the code in obtaining ‘social licence’ from local communities for hazardous waste storage facilities where Australian governments have for decades failed, approaching the issue with what Tellus describes as a “disruptor attitude”.
CEO Nate Smith has addressed the US Nuclear Regulatory Commission and the International Atomic Energy Agency’s annual conference on what is known within the nuclear industry as “consent-based siting”, and was the only international participant at the 2024 US Department of Energy’s “success in siting” roundtable.
“Tellus’s agreement in October 2023 with the Titjikala traditional owner group near Alice Springs… demonstrates social licence can be achieved for complex and potentially controversial projects if the right foundations are laid”, says Tellus’s submission to a parliamentary inquiry into nuclear power generation in Australia.
Key to achieving social licence, it claims, is building trust through engagement. In a half-hour appearance before the same parliamentary inquiry, on 17 December 2024, the Tellus CEO used the word “trust” seventeen times.
Likening frontline Aboriginal communities to children refusing to eat their vegetables, the Tellus CEO described his company’s community engagement ethos:
“[I]f you go out and announce, ‘This is what’s going to happen,’ and then you engage, it’s like telling your kids, ‘You’re going to eat those green beans, and now I’m going to tell you why they’re good.’ No. Tell them why they’re good first. You have to build the trust first”.
“Trust”, a Tellus webpage proclaims, “is the bedrock of our business”. This trust doesn’t appear to extend to fully informing native title holders of the waste streams, including from nuclear submarines and other military sources, that Tellus looks to be seeking to secure for its prospective Chandler Project.

Tellus Holdings & AUKUS
Tellus Holdings bills the Chandler dump as “supporting Australia’s green energy transition” by providing a place to permanently store hazardous by-products associated with critical minerals mining.
However, the dump is also likely to become a repository for hydrocarbon wastes and by-products from oil and gas commissioning, as well as the radioactive materials derived from oil and gas extraction processes.
In his many public appearances, Tellus CEO Nate Smith is fond of saying “there is not a power source that exists in the world that doesn’t create massive amounts of low-level radioactive or chemical wastes”.
Smith claims that Tellus is “agnostic” with regards to Australia’s energy mix, though he recently appeared on a panel about “Australia’s nuclear future” convened by ‘Nuclear for Australia’, a pro-nuclear lobby group. Nuclear for Australia is partly funded by Australian millionaire Dick Smith and fronted by teenager Will Shakel, who has links to the Liberal Party.
Tellus’s US advisory partner in the Chandler Project, Amentum Holdings, doesn’t seem to share Tellus’s agnosticism. Offering plenary remarks at the 2025 Waste Management Symposia in Arizona, Amentum’s president for Energy and Environment, Mark Whitney, described nuclear and radioactive waste management as a “major component of our ability to expand global nuclear capacity”.
The Tellus CEO is less shy in telegraphing the role he says Tellus can play in getting the beleaguered AUKUS nuclear submarine program back on track, and is openly making a pitch for his company to receive AUKUS submarine waste.
“Tellus has the only management team in the world, government or private, that has run a successful radioactive waste disposal project end to end… That innovation is here for Australia’s use, and it is a valuable way to de-risk AUKUS or, if we choose, other nuclear program delivery”, he told Coalition and Labor MPs in December 2024.
In contradistinction to skeptical AUKUS commentators, Smith insists that the only thing preventing Australia from hosting nuclear submarines from as early as 2027 is the need for a site to store the nuclear waste they produce.
Fortunately, he says, Tellus’s already-operational Sandy Ridge facility, 240 kms northwest of Kalgoorlie, stands ready to accept the waste. “The near-term issue that’s threatening the AUKUS plan delivery is the low-level [radioactive waste], and that’s already solved so why reinvent the wheel”, Smith told Adelaide’s FIVEAA Radio.
Speaking before the Australian senate inquiry into nuclear power generation in December 2024, Smith told the committee that“it is the low-level radioactive waste, not the high-level radioactive waste, that will be the year-to-year issue in our lifetimes as AUKUS subs, as soon as 2027, and/or future reactors go through standard annual maintenance. I’m here to tell you that Australia already has the capability today to dispose of that at Sandy Ridge”.
The Chandler Project vs Tellus’s Sandy Ridge facility
Tellus’s Sandy Ridge low-level nuclear waste storage facility has been operational since 2021 and is described by the company as Australia’s “first commercial hazardous waste geological repository”.
When Tellus submitted the proposal for its Sandy Ridge facility to Western Australia’s Environmental Protection Authority in 2015, then CEO David van de Merwe “publicly stated the facility would not take nuclear waste and was only looking to take a small volume of medical isotopes”.

When Tellus received conditional approval for its Sandy Ridge facility from the WA Environmental Protection Authority in 2017, it was for “non-nuclear low-level radioactive waste”. Seven years later, the current Tellus CEO Nate Smith insists that to overlook Sandy Ridge as a storage facility for low-level AUKUS submarine waste would be to “reinvent the wheel”. Tellus is now lobbying the Department of Defence for permission to store nuclear waste from AUKUS submarines.
Effectively a glorified trench dug into kaolin clay and covered by a dome resembling a bouncy castle, the Sandy Ridge facility cost $80 million AUD to build and is just 30 metres below surface level at its deepest.
Tellus’s Chandler Project, on the other hand, is conservatively projected to cost between $445 – $648 million AUD to construct. The Tellus CEO has said that the construction of the Chandler Project will likely be up to “10 times” the cost of Sandy Ridge.
Waste at the Chandler Project will be stored 860 metres below surface level – 205 metres deeper than New Mexico’s Waste Isolation Pilot Plant, which is used for storing transuranic radioactive waste derived from military sources. Yet Tellus Holdings claims that it intends for the Chandler Project to store low-level nuclear waste, just like Sandy Ridge.
In a significant moment during his appearance before the Parliamentary Inquiry into Nuclear Power Generation in Australia, Nate Smith was asked by the Labor MP Matt Burnell to describe the difference between a low-level nuclear repository and a high-level one.
In answering, Smith proceeded to effectively describe the basic differences between Tellus’s Sandy Ridge facility and its prospective Chandler Project (without naming the Chandler Project):
“What we are [at Sandy Ridge] is a near-surface repository. It’s an open-cut mine where we excavate about 30 metres down into a deep kaolin clay bed, and there’s granite underneath it. What we do is emplace waste in layers, almost like a cake. We compact it, we have a seal, and it sits throughout geological time. That can take low-level radioactive material, and in some cases, in the United States, they’re considering taking intermediate material in those types of facilities.
“To take high-level radioactive waste, you instead need to have a deep geological repository, not an open-cut mine. You have to burrow several hundred metres down into the earth, typically in salt or some hard rock like granite. There, you dispose of it deeper underground. Because of the type of radionuclides, you need additional safety, so that’s why you go deeper.”
Smith’s characterisation of the respective engineering requirements for low-level and high-level radioactive waste repositories echoes a description provided by the Sustainability Directory in a course on the fundamentals of radioactive waste disposal economics:
“Low-level waste (LLW), often composed of contaminated tools, clothing, and equipment, requires relatively straightforward handling and disposal, typically in near-surface facilities.
“Intermediate-level waste (ILW), containing higher concentrations of radioactivity or requiring shielding, often necessitates disposal in deeper repositories. High-level waste (HLW), primarily spent nuclear fuel from reactors or waste from fuel reprocessing, is intensely radioactive and generates heat, demanding robust, long-term isolation solutions like deep geological repositories”.
Tellus is going to the enormous cost and effort of building a new facility ostensibly to store low-level nuclear waste despite already operating such a facility in Western Australia.
The new site will require up to ten times the capital expenditure (before any cost blow-outs) of the existing Sandy Ridge facility, and stands to be vastly more complicated in engineering terms.
It is not clear why Tellus is planning to develop the Chandler facility for low-level nuclear waste storage when the company could, on the face of it, simply expand or replicate its existing Sandy Ridge facility at a much lower cost and with much less effort.
It is difficult to glean a clear answer from Tellus’s available commentary on the project. The following considerations can be made on what sort of hazardous waste may be stored at the Chandler Project, and its relationship to the burgeoning AUKUS military industrial complex.
Dumping the AUKUS waste
The Australian Submarine Agency has admitted that intermediate-level radioactive waste shed by nuclear submarines during routine operational maintenance will be stored in Australia.

Eventually, when these submarines are decommissioned, Australia will have to find a place to securely store the submarines’ nuclear reactors, containing weapons-grade uranium.
Australia is now a permanent base for UK and US nuclear submarines patrolling the Indian Ocean, using the HMAS Sterling base near Perth, for docking and maintenance of the submarines.
Given that the lifespan of the S9G nuclear reactors on the Virginia Class submarines is approximately 33 years, and the submarines projected to be stationed in Australia from 2027 will be between 3 – 23 years old, decommissioning in Australia could occur as early as 2037.
It appears that Chandler is being built with an eye to accommodating intermediate and high-level AUKUS nuclear waste, despite the fact that it is billed as a facility for naturally occurring radioactive material only.
No approval, no problem
Tellus’s Chandler Project does not currently have environmental approval to store nuclear waste of any kind. In order to accept such waste at its Chandler Facility, Tellus would have to seek amendments to its existing environmental impact assessment, or apply for a new one.
In addition to this, the company would need to pursue a new Indigenous Land Use Agreement with native title holders.
Tellus would also have to seek changes to or exemptions from the NT Nuclear Waste Transport, Storage and Disposal (Prohibition) Act 2004, which prohibits the disposal of waste containing radioactive material derived from the operation or decommissioning of a nuclear plant (including a nuclear reactor), from nuclear weapons activities, or from the conditioning or reprocessing of spent nuclear fuel.
The Central Land Council’s submission regarding Tellus’s environmental impact assessment for the Chandler Project raised the possibility of the Chandler facility accepting higher categories of radioactive waste once it is built, citing a risk that “once a geological hazardous waste repository is in operation there could be significant political pressure to broaden the acceptance criteria policy”.
At the recent Northern Australia Contaminated Land and Groundwater conference in Darwin, an attendee reports, a Tellus representative told conference attendees:
“The geology at Chandler would make it possible to store higher level radioactive waste”.
In response to a question on whether the Chandler dump was intended to store nuclear waste from international sources, the Tellus representative confirmed that it indeed was, and made it clear that Tellus was seeking to have government regulations modified to broaden waste acceptance criteria:
“We do feel that as good global citizens we should be helping to – if we’ve got the geology to offer a safe space, and a controlled, regulated environment for that waste – then we should play in that space.
“And absolutely, there is a huge commercial opportunity, particularly for the Northern Territory, if we were to do that. So a huge benefit in doing that, and we do have that guarantee of having a safe space.
“But we need the regulators, the public, and the politicians to agree to that. Just watch that space..”
Waste from expanding militarisation
Northern Australia is currently subject to a huge expansion in US military presence. For the fiscal year 2024/2025, northern Australia is “the top overseas location for U.S. Air Force and Navy construction spending, with more than $300 million set aside under the U.S. congressional defence authorisations for those years”, Reuters reports.
Over the next decade, the Australian government will spend $30 billion on “hardening and upgrading” northern military bases,“partly to meet US requirements and partly paid for by the United States”. This expanded presence will be accompanied by an expanded military waste footprint.
The Tindal Air Base, located just outside of Katherine, is currently undergoing a major upgrade that will include squadron operations facilities and maintenance infrastructure. The upgrade will allow for the permanent stationing of six US B-52 nuclear-capable bombers. B-52s, the last of which was manufactured 64 years ago, are notorious for requiring regular extensive maintenance that produces significant amounts of hazardous waste.
Maintenance of B-52s stationed at the Barksdale Air Force Base in the US, for example, produced “thousands of tons of powder, with dangerous trace metals and chemicals, from sandblasting and cleaning aircraft”, including chromium, arsenic, lead and cadmium.
This waste from the Barksdale Air Force Base provoked a significant scandal in the US that put the topic of outsourced hazardous waste management on US military bases in the public spotlight. Experts say that the US Department of Defence incentivised “shortcuts and outsourcing” in order to “preserve the Pentagon’s primary military mission”.
In making its pitch to the Australian Department of Defence for taking low-level nuclear waste from AUKUS submarines, Tellus played on the same instinct: “Government resources would be free [to] focus on mission critical challenges of AUKUS that do not yet have a solution”.
Encouraging the government not to provide oversight of hazardous waste management from military sources has proven to be highly problematic. An investigation into the US military’s use of contractors for hazardous waste disposal found that “in outsourcing this work, the military has often struggled to provide adequate oversight to ensure that work is done competently — or is completed at all”.
As the urgent drumbeat of war intensifies and the Department of Defence becomes increasingly preoccupied with “mission critical challenges”, so too do the risks from military waste clean-up work.
Tellus Holdings emphatically claims to have “solved” the inherent dangers associated with nuclear waste storage. However the flawed safety record of its contractor on the Chandler nuclear waste dump, Amentum, underscores the enduring threat of radioactive waste disposal, and the lack of transparency surrounding nuclear waste management on this continent.
With the Southern Arrernte community of Titjikala just 15 kms from the proposed Chandler nuclear waste site, any mistakes such as those that have already occurred with US military nuclear waste would be catastrophic for them, especially if ‘slippage’ occurs in terms of the kind of waste the facility accepts.
