APRA APS 330 Public Disclosure: Pillar 3 reporting for ADIs

What APS 330 is

APS 330 is the Australian prudential standard that requires authorised deposit-taking institutions (ADIs) — banks, building societies and credit unions — to publicly disclose key prudential information about their capital, liquidity and risk. It is APRA's implementation of "Pillar 3" of the Basel capital framework, the market-discipline pillar that sits alongside minimum capital requirements (Pillar 1) and the supervisory review process (Pillar 2). The purpose is to give depositors, investors and analysts a consistent, comparable view of an ADI's financial resilience.

The standard is administered by the Australian Prudential Regulation Authority (APRA) and is published in the APRA Prudential Handbook. The current version of APS 330 commenced on 1 January 2025 and aligns Australia's disclosure regime with the Basel Committee on Banking Supervision (BCBS) revised Pillar 3 framework.

If you are searching for "APS 330", you are almost certainly trying to work out one of three things: whether it applies to your institution, what you have to publish, and when. This explainer covers each in turn. It sits within the broader financial services regulatory framework.

Who APS 330 applies to

The scope of APS 330 narrowed significantly under the version that commenced in January 2025. The full disclosure obligations apply to ADIs that are locally-incorporated significant financial institutions (SFIs).

In broad terms:

• Locally-incorporated SFI ADIs — typically the larger banks — carry the full disclosure burden under the standard.
• Non-SFI ADIs (smaller banks, mutuals and credit unions) are generally not required to make their own disclosures under APS 330 in the same way. Instead, key prudential and financial data for these entities is published through an APRA-operated centralised publication (discussed below).
• Foreign ADIs (branches of overseas banks) and purchased payment facility providers are generally excluded, though APRA reserves the right to apply the standard to a particular entity.

Whether an ADI is an SFI is determined under APRA's prudential framework using size and complexity criteria. Because the SFI test and the precise scope can change, confirm your institution's classification directly with APRA rather than relying on a general description — the line between SFI and non-SFI determines your entire obligation. Verify the current SFI thresholds and definitions with APRA.

What must be disclosed

APS 330 requires an ADI to make disclosures that are clear, comprehensive, meaningful, consistent and comparable, so as to contribute to the transparency of financial markets and enhance market discipline. The substance follows the BCBS Pillar 3 disclosure templates, adjusted by APRA for the Australian context.

The disclosures cover an ADI's risk profile and financial resilience across areas including:

• Regulatory capital — composition of capital, capital ratios and the reconciliation to the balance sheet.
• Key prudential metrics — a summary of an ADI's main capital, leverage and liquidity figures.
• Leverage ratio — the non-risk-based capital backstop.
• Liquidity — including liquidity coverage and net stable funding measures, where applicable.
• Credit risk and counterparty credit risk.
• Securitisation exposures.
• Market risk and interest rate risk in the banking book.
• Operational risk.
• Macroprudential / capital-buffer indicators.

The standard works hand-in-hand with the rest of APRA's capital framework — the disclosed figures are derived from the same definitions used for capital adequacy and liquidity reporting. Disclosures must reconcile to an ADI's regulatory returns and audited financial statements, so the numbers an ADI publishes under APS 330 should not be a separate calculation exercise.

Disclosure frequency, timing and format

Disclosure frequency under APS 330 is not uniform — it tracks the underlying BCBS templates, which are variously quarterly, semi-annual or annual depending on the metric. Capital and leverage summaries are typically more frequent; some narrative and detailed credit-risk tables are annual.

Key timing and format expectations:

• Concurrent publication — disclosures are generally required to be made available at or around the time an ADI lodges or publishes its corresponding financial reports, so that market participants receive prudential and financial information together.
• Dedicated location — disclosures are published in a clearly identified "regulatory disclosures" area so users can find the full current and historical set.
• Machine-readable data — quantitative information is expected to be provided in a structured, downloadable format (for example CSV or Excel, or another APRA-approved format) in addition to any narrative.
• Governance — an ADI must have a board-approved disclosure policy and appropriate internal controls to ensure the information is accurate and consistent with its other regulatory submissions.

Because exact frequencies and submission timing attach to individual templates, check the relevant template requirements in the APS 330 standard rather than applying a single blanket deadline.

The APRA centralised publication

A defining feature of the current regime is that APRA itself publishes prudential and financial data for ADIs through a centralised publication, rather than every small ADI maintaining a full Pillar 3 disclosure suite on its own website.

This approach was designed to:

• reduce the disclosure burden on smaller, non-SFI ADIs;
• improve comparability by presenting data in a standard form across institutions; and
• give the public a single, consistent source for entity-level key metrics.

For larger SFI ADIs, the obligation to make comprehensive disclosures continues. For other ADIs, much of the relevant transparency is delivered via APRA's published data. APRA has consulted on the confidentiality and scope of the data included in the centralised publication; the precise data items and their treatment can evolve, so confirm what currently sits in the centralised publication versus an ADI's own obligations with APRA's ADI public disclosure pages.

What ADIs should do

A practical compliance path for an in-scope ADI:

1. Confirm scope. Establish in writing whether your ADI is a locally-incorporated SFI, and therefore subject to the full standard, or whether your data is covered through the centralised publication.
2. Map the templates. Identify every BCBS/APRA disclosure template that applies to you and its frequency (quarterly, semi-annual or annual).
3. Build the data lineage. Ensure the figures trace directly to your regulatory returns and audited accounts so disclosures reconcile and cannot diverge.
4. Set the calendar. Align each disclosure to the lodgement of the relevant financial report and build internal sign-off time before publication.
5. Document governance. Maintain a board-approved disclosure policy, with controls over accuracy, review and retention of prior disclosures.
6. Publish accessibly. Provide both readable and machine-readable formats in a clearly labelled regulatory disclosures section.

Common pitfalls

• Assuming the old regime still applies. The standard changed materially from 1 January 2025; disclosure suites built for the previous version may over- or under-disclose. Re-map against the current standard.
• Treating APS 330 as a separate calculation. Disclosed numbers must reconcile to regulatory reporting and financial statements. Divergence is a red flag for both auditors and APRA.
• Misjudging SFI status. Getting the SFI classification wrong leads either to unnecessary effort or to a genuine compliance gap. Confirm it with APRA.
• Late or non-concurrent publication. Publishing disclosures well after the related financial report undermines the market-discipline purpose and can breach timing expectations.
• Neglecting machine-readable data. Publishing only a PDF narrative when structured data is required is a frequent and easily avoided failure.
• Relying on out-of-date figures. Frequencies, templates and the contents of the centralised publication can change. Where you are unsure of a specific requirement, verify the current position with APRA before publishing.

APS 330 is ultimately about transparency: giving the market a reliable, comparable window into an ADI's capital and risk. For in-scope institutions, the work is less about new calculations and more about disciplined mapping, reconciliation and timely publication.
