Beyond FIRB:
Australian Mining Compliance
— Obligations After Completion

FIRB Approval Is Not the End of the Compliance Work

For an offshore buyer of an Australian mining asset, the FIRB approval letter — the Treasurer's no-objection notification under the Foreign Acquisitions and Takeovers Act 1975 (Cth) (FATA) — is the most visible regulatory event in the transaction timeline. It is what the board, the financiers, and the offshore counsel are watching. And it is where most of the pre-completion compliance work gets focused.

Once the FIRB letter is issued, the buyer takes over operation of the asset. The rules that govern how it is operated — the rules that decide whether the tenement gets renewed, whether the next mining proposal gets approved, whether the asset can be sold later, and whether the board can stand behind the compliance representations it has given to its lenders and investors — are almost entirely state-based. A federal layer also continues to apply after completion.

That state framework is not optional. It is not waiveable through the FATA conditions. And it runs on its own statutory schedule — annual returns, annual reports, scheduled reviews, event-based notifications — regardless of who owns the asset.

Federal Obligations That Continue After FIRB Approval

The federal compliance obligations that operate after FIRB approval have four parts. Each one is administered by a different Commonwealth agency, and each one carries its own penalty exposure for the new owner.

Register of Foreign Ownership of Australian Assets (ATO)

The Register of Foreign Ownership of Australian Assets, administered by the Australian Taxation Office, commenced on 1 July 2023. It is the most commonly missed federal obligation. Foreign persons acquiring an interest in a mining, production, or exploration tenement, or an interest of at least 10 per cent in the securities of a mining, production, or exploration entity, must notify the Registrar through the ATO's Online Services for Foreign Investors within 30 days of the registrable event. Failure to register attracts civil penalties of up to 250 penalty units per day. The register operates as a continuing obligation. Subsequent events — disposals, changes in proportional holdings, ceasing to be a foreign person — also trigger notification.

FATA Conditions

FIRB approvals issued under FATA are routinely granted on conditions. The conditions are binding on the buyer for the life of the investment. They may include tax conditions, reporting conditions, divestment triggers, Australian-presence requirements, processing-in-Australia obligations, and notification of subsequent material changes. Treasury and the Foreign Investment Compliance function have stepped up enforcement in recent years, including through ongoing monitoring and engagement with foreign investors after no-objection notification.

Critical Minerals Call-In Power

For tenements that touch a critical minerals list commodity — lithium, rare earths, cobalt, nickel, graphite, copper, vanadium, and others — the national security review framework introduced under the 1 January 2021 FATA reforms is the most likely entry point for further regulatory scrutiny. The Treasurer's call-in power under FATA can be exercised within ten years of an investment that was not previously screened on national security grounds. A change in geopolitical posture, a change of investor character, or a subsequent transaction within the holding structure can re-engage that review.

EPBC Act

Federal environmental approval under the Environment Protection and Biodiversity Conservation Act 1999 (Cth) (EPBC Act) is independent of FIRB. Any new mining action with a significant impact on a matter of national environmental significance — listed threatened species, Ramsar wetlands, world heritage, national heritage, the Great Barrier Reef, Commonwealth marine areas, or, following the expansion of the water trigger in late 2023, a water resource in relation to large coal mining and unconventional gas developments (including shale and tight gas) — requires referral and assessment regardless of who owns the proponent. The Environment Protection Reform Bill 2025 and related package passed the Senate on 27 November 2025; until commencement and the making of associated regulations, standards, and guidance, the EPBC Act framework continues to operate as the controlling federal environmental regime.

The State Rules Where Buyers Most Often Stumble

Most of the compliance work after FIRB approval happens at the state and territory level. Every Australian jurisdiction with active mining operates its own Mining Act, its own primary approval instrument, and its own annual reporting schedule. There is no national equivalent. There is no reciprocal recognition between states. A mining proposal approved in WA does not carry across to another state.

At completion, the offshore buyer needs to list every tenement in the deal, identify the approval that authorises operations on each, and check every annual obligation against that tenement's grant-date anniversary — not the calendar year, and not a single portfolio-wide date.

The Seven-Jurisdiction Snapshot

Two things matter when reading this table. First, the seven jurisdictions are at different stages of regulatory change. WA has recently landed a major change to its primary operational approval instrument; NT is mid-transition under a new environmental licensing regime; NSW and VIC have amendment regimes in flight. A buyer who relies on a two-year-old desktop compliance assessment is working from the wrong framework. Second, the primary instrument is only the headline. Each Act sits over a regulation, a guideline set, and a department-published expectations document that materially shapes what compliance actually looks like in practice.

The Most Common State-Level Failures

In our work for offshore buyers after completion, the recurring failures cluster:

• Annual reporting deadlines tracked against calendar year rather than each tenement's grant-date anniversary, leading to missed lodgements on tenements with mid-year anniversaries
• Expenditure reporting kept the same as the previous owner did it, without checking how the regulator now treats overhead, desktop work, and apportionment
• Mining proposals or work plans that are several years old and no longer reflect current operations, with no amendment lodged
• Rehabilitation cost estimates that have not been re-priced against current contractor rates or current disturbance
• Conditions of approval (especially water, native vegetation, and heritage conditions) that have quietly accumulated obligations the new operations team is unaware of

None of these is unusual. All of them turn up in a post-completion compliance review. None can be spotted from the deal data room alone.

Native Title and Aboriginal Heritage

The native title and Aboriginal heritage frameworks are the area where an offshore buyer is most likely to inherit obligations that are real, ongoing, and not visible from the deal documents.

Native title in Australia is governed by the Native Title Act 1993 (Cth), with parallel state and territory legislation administering Aboriginal heritage. Most operating mining tenements in Australia sit over land that is the subject of a determined native title group, a registered claim, or both. The relationship between the tenement holder and the native title parties is typically governed by an Indigenous Land Use Agreement (ILUA) or equivalent ancillary agreement, registered with the National Native Title Tribunal.

The treatment of these agreements at completion depends on the transaction structure.

In a share or corporate restructure, the tenement holder does not change, and registered ILUAs and ancillary agreements continue to bind the tenement holder, by their terms, unchanged. The change of beneficial ownership upstream does not, of itself, novate or terminate the agreement. However, many ILUAs contain change-of-control notification provisions, consultation requirements, or trigger events that engage on a change in the corporate ownership of the tenement holder. Those provisions need to be read individually.

In an asset transfer, the position is typically different. Tenement transfers in Australia generally require ministerial consent under the relevant Mining Act, and the consent process customarily includes an assessment of whether the transferee will assume the tenement holder's existing native title and heritage commitments. Registered ILUAs do not automatically transfer with the tenement; in current Australian practice the transferee most commonly assumes the obligations through a deed of assumption or equivalent, executed as part of the transfer. The specific treatment of registered agreements at transfer should be confirmed with Australian native title counsel on a transaction-by-transaction basis; the deed-of-assumption pathway is the most common but is not universal, and individual ILUAs may displace or supplement it.

Separately, Aboriginal heritage obligations under the relevant state and territory Aboriginal heritage statutes apply to the tenement holder regardless of corporate or asset structure, and apply whether or not native title is determined. The specific statute, and its current operative form, varies materially by jurisdiction and should be confirmed against the assets in the deal.

The task at completion is the same in every case. The buyer needs a current register of every Indigenous agreement on every tenement, the change-of-control provisions in each, and the standing heritage obligations under the applicable state statute. That register rarely exists in the data room in a form anyone can use.

The Compliance Calendar

A full annual compliance calendar for an Australian mining portfolio covers about forty separate obligations. The headline categories are the ones an offshore buyer needs to staff for from day one of operations.

Annual obligations include the state mining Act annual report or return (form varies by jurisdiction); the annual rehabilitation report or equivalent (NSW Annual Rehabilitation Report; WA Annual Environmental Report; SA MARCR; NT environmental licence annual report); the annual royalty return to the relevant state revenue authority; the tenement rent payment to the mines department; and, where the assets in the deal include EPBC-conditioned projects, the annual compliance report to DCCEEW. Expenditure reporting against minimum annual expenditure commitments is licence-year-anchored, not calendar-year-anchored.

Quarterly or six-monthly obligations typically include royalty instalments, environmental monitoring data submissions under licence conditions, and water-use returns under state water acts.

On-event obligations are the ones that catch new operators out. Tenement transfers, changes in registered holder, changes of operator, changes of registered office, appointment and removal of Registered Agents (WA), variation of mining proposals or work plans, changes in disturbance footprint, incident notifications, environmental harm reports, native title agreement triggers, and federal Register of Foreign Ownership updates all carry statutory notification windows measured in days rather than months.

Missing an annual deadline typically attracts a rectification notice and an additional condition. Missing an on-event deadline can attract a strict-liability penalty and, in serious cases, a forfeiture process. The asset is most exposed in the first twelve to eighteen months after completion, when the new operations team's familiarity with the calendar is still at its weakest. Practical tenement management is the discipline that keeps this calendar live.

IA-CEPA and Bilateral Treaty Frameworks

For offshore buyers from FTA partner countries, a bilateral treaty framework may sit alongside the FATA regime and change the FIRB threshold that applies. The most operationally relevant treaty for Indonesian, ASEAN, and broader Indo-Pacific investors is the Indonesia-Australia Comprehensive Economic Partnership Agreement (IA-CEPA).

The IA-CEPA entered into force on 5 July 2020 and sits alongside the ASEAN-Australia-New Zealand Free Trade Agreement (AANZFTA), the Regional Comprehensive Economic Partnership (RCEP), and the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP). For Indonesian private (non-government) investors, the IA-CEPA delivers an elevated screening threshold for non-sensitive investments, aligning Indonesia broadly with other FTA-country investor treatment for the purposes of FATA monetary thresholds.

Three points need to be understood clearly.

First, the elevated threshold does not extend to mining or production tenements. Under FATA and the Foreign Acquisitions and Takeovers Regulation 2015 (Cth), acquisitions of interests in mining or production tenements are notifiable regardless of value for almost all foreign investors, with limited carve-outs for certain FTA-country private investors that do not currently include Indonesia.

Second, the elevated threshold does not extend to foreign government investors. A state-owned enterprise from any country, including IA-CEPA partner countries, is treated as a foreign government investor and is subject to the $0 threshold for mining and production tenement acquisitions.

Third, no bilateral treaty switches off the Treasurer's call-in power, the national security regime, or the critical minerals scrutiny. IA-CEPA is a market-access framework. It is not a national security framework.

The IA-CEPA matters for transaction structure and for the FIRB filing pathway. It does not change the compliance obligations that continue after FIRB approval, set out in the sections above. Those obligations apply to every foreign holder of an Australian mining asset, regardless of the treaty under which the transaction was screened.

What Good Post-FIRB Compliance Looks Like

The buyers who manage post-FIRB compliance well do a small number of things consistently. They are not complicated, but they are often missing.

A current tenement and obligations register, tracked from each tenement's grant-date anniversary rather than calendar dates, covering every tenement in the deal, every active approval instrument, every condition of approval, and every Indigenous agreement on every tenement. The register lives outside the deal data room and is updated continuously.

A named person responsible for compliance, recognised by the regulator. In WA this is a Registered Agent under the Mining Act 1978 (WA); in other jurisdictions it is the equivalent registered manager, mine manager, or environmental officer. The role is held by a named individual whose contact details sit with the regulator and whose appointment is recorded against every tenement. Offshore buyers without a local presence often appoint a Registered Agent under an external arrangement; the appointment must be formalised, not assumed.

A reporting schedule aligned with the regulator's, not the buyer's parent-company financial year. The annual report under the state mining Act is the regulator's primary view of the asset. It is read by the assessment team that will decide the next mining proposal, the next renewal, and the next transfer consent. A late or incomplete annual report damages the relationship the operator will need for every future approval.

A live record of FATA conditions held against the corporate file, with annual confirmation that the conditions have been met. FIRB approval carries continuing obligations through any FATA conditions attached, and the Treasury compliance function actively monitors them.

A defined process for on-event obligations — share transfers, changes of operator, disturbance changes, incidents, native title triggers. These obligations carry the tightest statutory windows and cause the most problems when missed.

These habits are not unique to mining or to foreign owners. In our work for offshore buyers, they are the difference between an Australian mining asset that operates cleanly under foreign ownership and one that spends too much management time fixing compliance problems that could have been avoided.

Where to Start

For offshore counsel and compliance directors at companies that have either cleared FIRB on an Australian mining asset, or are evaluating one ahead of bid, the starting point is a structured post-acquisition compliance health check. The aim is to identify the gap between the deal data room and the actual statutory position on every tenement, before the first annual reporting deadline exposes it.

Sceptre Strategic provides post-acquisition compliance reviews, retained compliance officer engagements, and tenement management support for international holders of Australian mining assets across all seven jurisdictions. The Practice works directly alongside clients' FIRB legal advisers and Australian counsel as part of the broader compliance pathway.
