The Australian Department of Industry, Science and Resources is pressing former senator Rex Patrick to face up to $150,000 in legal costs if he loses an ongoing federal court fight over AUKUS nuclear waste documents, escalating a freedom-of-information dispute that has drawn crossbench outrage and transparency-group intervention.

Patrick, an independent senator for South Australia from 2017 to 2022, used freedom of information laws to seek details on where nuclear waste from the AUKUS submarine fleet will be stored. He won an administrative appeal on the matter in May 2026, securing the right to see most of the documents on nuclear waste sites the government is scoping for AUKUS. The Department of Industry, Science and Resources then appealed that FoI decision to the federal court and is seeking a court order requiring Patrick to pay the government's legal costs if he loses. Previous legal fights of this nature have seen fees as high as $150,000. Patrick has partially won a court order capping the maximum legal costs he would have to pay if defeated, though exposure remains substantial.

The department does not accept that model litigant rules prevent it from pursuing costs against Patrick. Model litigant rules require the Commonwealth to act as a model litigant in legal proceedings, generally restraining government lawyers from pursuing tactics that would unfairly burden an opponent. Attorney General Michelle Rowland has weighed in directly, writing to crossbenchers including Helen Haines, David Pocock, and David Shoebridge to say the government could rightly insist Patrick pay costs if he loses. Rowland stated that the industry department was responsible for the conduct of the FoI case.

The response from across the political spectrum has been sharp. Senator Jacqui Lambie accused Rowland of "behaving like a Labor stooge." Lambie and Senator Pauline Hanson both warned that the costs order breaches model litigant rules requiring the government to act as a model litigant. Media and civil-society organisations have also mobilised. The Media Entertainment & Arts Alliance, the Grata Fund, the Alliance for Journalists' Freedom, and the Australian Democracy Network all called on the government to withdraw the legal challenge. Unions and transparency groups made direct appeals to Rowland but were rebuffed.

The broader context here is a collision between two principles the Commonwealth is normally expected to uphold simultaneously: transparency through freedom of information, and responsible stewardship of litigation costs. The AUKUS nuclear waste question sits at a particularly sensitive intersection. The submarine program involves decades-long commitments to nuclear stewardship, and the question of where high-level waste will be stored is among the most domestically contentious elements of the pact. FoI requests of the kind Patrick filed are the primary mechanism by which Parliament and the public can scrutinise site selection and planning. When an administrative tribunal has already ruled that most of the documents should be released, a departmental decision to escalate to federal court, and to attach the threat of six-figure personal liability to the requester, functions as a significant deterrent to future FoI litigation, regardless of the government's stated rationale.

The model litigant dispute is the legal pivot. The Commonwealth's own guidelines oblige government agencies to handle litigation fairly and without using superior resources to pressure opponents. The department's position, that it is not constrained by those rules from seeking costs, is a narrow reading that, if accepted by the court, would narrow the practical protection model litigant rules afford to FoI appellants. Rowland's deflection of responsibility to the industry department on conduct grounds is consistent with that posture: the Attorney General endorses the department's right to pursue costs while disclaiming ownership of the decision. Whether that separation holds up under political scrutiny is a separate question from its legal validity.

The cost-cap Patrick secured is a partial buffer but not a guarantee against financial ruin for an individual litigant. Even a capped exposure in the tens of thousands of dollars is a material burden for a private requester pursuing documents that an administrative tribunal has already ordered released. The signalling effect extends beyond this case: any journalist, researcher, or parliamentarian weighing whether to escalate an FoI refusal to court will now have to price in the possibility that the Commonwealth will pursue personal costs.

Patrick's case will turn on the federal court's assessment of both the underlying FoI decision and the permissibility of the costs order. Whatever the outcome, the episode has already exposed a structural tension in how the government balances AUKUS-era secrecy obligations against statutory transparency commitments, and the gap between the two is likely to widen as the submarine program advances.
