Lobbying (Improving Government Honesty and Trust) Act 2025: national register and post‑office limits

Creates a mandatory Register of Lobbyists, quarterly reporting, monthly Ministerial diary publication and a 3‑year cooling‑off for former Ministers and senior advisers — enforced by the National Anti‑Corruption Commissioner.

The Brief

The bill establishes a national, electronic Register of Lobbyists overseen by the National Anti‑Corruption Commissioner, requires registered lobbyists to submit quarterly returns detailing who they met and what they sought, and makes it an offence for professional and in‑house lobbyists to engage in lobbying while unregistered. It also places substantive conduct obligations on registered lobbyists (conflict separation, disclosure of clients, limits on gifts and hospitality) and requires Ministers to publish monthly Ministerial diaries and to keep senior Ministerial staff recorded in the Australian Government Directory for at least three years after they leave.

The Act imposes a three‑year post‑employment restriction on former Ministers and senior Government advisers for matters they had official dealings with in their last three years in office and gives the Commissioner investigation powers under the National Anti‑Corruption Commission Act 2022, with serious contraventions carrying penalties of 100 penalty units. The combination of public registers, periodic reporting and enforceable post‑office limits materially raises transparency and compliance obligations for lobbyists, former officials and agencies that must maintain and publish records.

At a Glance

What It Does

The bill makes most professional and qualifying in‑house lobbyists register with the Commissioner, submit quarterly returns (topics, government contacts, dates, participants and—where applicable—client ABNs), and comply with conduct principles including client disclosure and limits on gifts and hospitality. It bans unregistered lobbying and establishes a 3‑year cooling‑off for Ministers and senior advisers on matters they handled.

Who It Affects

Professional lobbyists, in‑house lobbyists who meet the 8‑hour/financial thresholds, third‑party clients of lobbying firms (with a limited confidentiality carve‑out), former Ministers and senior Government advisers, Ministers required to publish diaries, and the Attorney‑General’s Department which must host the Register.

Why It Matters

This is a prescriptive, enforceable transparency scheme rather than a voluntary code: it creates routine public reporting, criminal penalties for unregistered activity and a statutory post‑employment bar. It centralises enforcement in the National Anti‑Corruption Commissioner but preserves a Ministerial power to direct registration decisions — a structural feature with practical and political implications for independence.

What This Bill Actually Does

The bill defines two categories of lobbyist: professional lobbyists who act for third‑party clients and in‑house lobbyists who meet both activity and entity thresholds (8 hours in a month across at least three months and either $100,000+ remuneration for lobbying staff or $5 million+ revenue, or being an industry association). Lobbying activity is broadly defined as any activity with or relating to a Government representative intended to influence government decisionmaking, but the bill lists routine exclusions (constituent communications, parliamentary committee submissions, grassroots campaigning and certain professional services).

Registered lobbyists must file a return within five business days after each quarter listing each lobbying activity, the topic and desired outcome, the government contacts involved, communication form, dates and the persons directing and undertaking the work. Professional lobbyists must additionally disclose third‑party client names, ABNs and related entities unless the lobbyist provides a notice saying disclosure would reasonably cause speculation about a pending transaction and the transaction is not already disclosed under continuous disclosure rules.The bill criminalises lobbying by unregistered professional and qualifying in‑house lobbyists (penalty: 100 penalty units) and imposes core conduct principles on registered lobbyists and listed persons: no corrupt or dishonest conduct, separation of lobbying from political or personal activities, proactive client disclosure to Government representatives, and restrictions on gifts and hospitality (limited to low‑value items).

It also forbids listed persons and in‑house lobbyists from playing a substantial campaign role during writs and for six months after an election.For former officeholders, the bill creates a targeted post‑employment restriction: former Ministers and senior Government advisers may not, for three years, lobby or advise for financial advantage on matters they had official dealings with in their last three years in office, nor provide advice that assists a lobbying activity on those matters. The Commissioner maintains and publishes the Register on the Attorney‑General’s Department website, may investigate alleged contraventions (applying investigatory powers under the National Anti‑Corruption Commission Act) and can refer alleged offences to the AFP.

The Minister may direct the Commissioner to refuse, vary, suspend or cancel registrations but must give notice and an opportunity to respond before doing so.The Act also requires Ministers to publish monthly Ministerial diaries of meetings and events relating to their responsibilities and to ensure current and former senior Ministerial staff are listed and linked to the Minister’s entry in the Australian Government Directory for at least three years after departure. The legislation includes review mechanisms: administrative review of Commissioner decisions, an expert-panel review of the Act within three to four years, and rule‑making powers for ancillary matters, subject to limits (rules cannot create offences or amend the Act).

The Five Things You Need to Know

1

An in‑house lobbyist is captured only if they spend at least 8 hours in a calendar month on lobbying for at least 3 months and the employer meets financial or structural thresholds (≥$100,000 on lobbying remuneration, ≥$5 million revenue, or is an industry association).

2

Quarterly returns are due by the fifth business day after each quarter and must list every lobbying activity’s topic, desired outcome, government contacts, communication form, dates and the persons directing and undertaking the activity; professional lobbyists must include client ABNs and related body corporate details.

3

The Act sets the criminal penalty for unregistered lobbying and for breaches of the post‑employment restrictions at 100 penalty units; administrative failures to update registration or confirm details carry penalties of 30 penalty units and can trigger suspension or cancellation.

4

Ministers must publish their previous month’s diary on the Attorney‑General’s Department website before the end of each month, including meetings with lobbyists and the attendees and key matters discussed; senior Ministerial staff entries must remain in the Australian Government Directory for at least three years after they leave.

5

The Commissioner investigates under the National Anti‑Corruption Commission Act 2022 (granting those investigatory powers) and may refer alleged offences to the AFP, but the Minister may also direct the Commissioner to refuse, vary, suspend or cancel registrations after giving notice and an opportunity to respond.

Part 2 (Sections 9–10)

Who counts as a lobbyist and what counts as lobbying

Sections 9 and 10 set the capture rules. The bill adopts a functional definition of lobbying (anything aimed at influencing government decisionmaking) but carves out routine public and professional interactions. It distinguishes professional lobbyists (acting for third‑party clients) from in‑house lobbyists and then layers financial and activity thresholds for in‑house capture (8‑hour rule plus entity tests: $100,000 on lobbying remuneration, $5 million revenue, or industry association status). That combination focuses registration burdens on actors with sustained, professional lobbying activity while excluding occasional technical advisers and visitors such as trade delegations.

Section 11

Ban on unregistered lobbying

Section 11 makes it an offence for captured lobbyists to engage in lobbying unless they are registered or are a listed person for a registered lobbyist, with a penalty of 100 penalty units. Practically, this creates a compliance gate: firms and qualifying in‑house staff must complete registration and remain current on reporting to lawfully meet Ministers or other Government representatives. The provision is broad and reaches communications ‘with, or in relation to’ Government representatives, which increases the risk that borderline activities will trigger criminal exposure unless clarified in rules or guidance.

Section 12

Post‑employment restrictions for Ministers and senior advisers

Section 12 imposes a targeted three‑year restriction on former Ministers and senior Government advisers: for three years after leaving office they must not, for financial advantage, lobby or provide advice on matters they handled in their last three years in office. The restriction covers both direct lobbying and providing advice that assists lobbying. The offence is penalised at 100 penalty units. This is a narrower alternative to a blanket lobbying prohibition — it focuses on matters of prior official responsibility rather than all post‑office activity.

Section 13

Conduct standards for registered lobbyists and listed persons

Section 13 sets behavioural obligations: no corrupt or dishonest conduct, no actions that unlawfully threaten detriment, reasonable efforts to verify information, separation of lobbying from political or personal activities, active disclosure to Government representatives of client names and the matters being raised, and limits on gifts and hospitality (only low‑value items or modest in‑person hospitality). It also bars lobbying where a close relationship would create a sense of obligation. These principles are enforceable and paired with criminal penalties, giving regulators teeth to act on conduct rather than only procedural breaches.

Parts 4 (Sections 15–17)

Register of Lobbyists and quarterly reporting

The Commissioner must establish an electronic Register published on the Attorney‑General’s Department website. The Register will list lobbyists, owners, listed persons, and, subject to a narrow confidentiality notice, third‑party clients with ABNs and related body corporate information. Registered lobbyists must lodge quarterly returns by the fifth business day after each quarter describing each lobbying activity, the government contacts, form of communication, dates, and personnel involved. The combination of a public, searchable Register and routine, granular returns is intended to allow external scrutiny but will require firms to develop repeatable reporting workflows.

Parts 4 (Sections 18–22)

Registration mechanics, statutory declarations and ministerial oversight

Applications must be on an approved form accompanied by statutory declarations from the lobbyist and listed persons attesting to criminal history and non‑membership of party executives. The Commissioner must register applicants unless satisfied of a serious contravention, in which case registration can be refused for up to 12 months; the Minister can direct the Commissioner to refuse, vary, suspend or cancel registrations but must give reasons and an opportunity to respond before doing so. The Commissioner also has procedural safeguards before varying or cancelling registrations, creating a hybrid model where an independent regulator operates alongside an explicit Ministerial supervisory power.

Parts 5–6 (Sections 23–26)

Ministerial diaries, staff directory entries and enforcement

Ministers must publish monthly diaries showing meetings and events related to their responsibilities, including attendees and key matters discussed. Ministers must also keep current and former senior Ministerial staff linked to the Minister’s entry in the Australian Government Directory for at least three years. Enforcement sits with the National Anti‑Corruption Commissioner, who may investigate on referral or on their own initiative, apply NACC investigatory powers to those inquiries and refer alleged offences to the AFP. The Commissioner’s investigatory status gives the regime significant investigative reach but interacts with the Minister’s directional powers and with administrative review avenues for regulated parties.

Who Benefits and Who Bears the Cost

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.

Who Benefits

  • Journalists, watchdogs and researchers — gain routine, machine‑readable reporting (Register plus quarterly returns and monthly diaries) that makes it easier to track who lobbies whom, when and about what.
  • Advocacy groups and NGOs — obtain a stronger evidentiary basis to hold government and commercial actors to account and to detect revolving‑door risks when former officials take private roles.
  • Compliant lobbying firms — receive a level playing field: firms that already disclose client relationships and follow codes of conduct can use the statutory Register as a market differentiator and face less competition from undisclosed operators.
  • Parliamentary integrity and compliance teams — get centralised data to support audit, conflict checks and proactive intervention, reducing information asymmetries between agencies and the public.

Who Bears the Cost

  • Professional lobby firms and qualifying in‑house teams — must build processes for registration, statutory declarations, quarterly returns (including ABNs and related body corporate details), and rapid update controls to meet 10‑business‑day and quarterly deadlines.
  • Former Ministers and senior Government advisers — face a three‑year constraint on monetised advisory and lobbying activity for matters they handled, which may constrict post‑office earning opportunities and require new legal advice on permitted activities.
  • Attorney‑General’s Department and the Commissioner — must host and maintain the Register, process applications, manage quarterly data inflows and run investigations, imposing ongoing resourcing and IT obligations.
  • Small entities that borderline the in‑house thresholds — may incur disproportionate compliance costs if they cross the $100,000 or $5 million triggers and must monitor staff hours to determine capture.

Key Issues

The Core Tension

The bill’s central dilemma is between public transparency and the protection of commercially sensitive or legitimate post‑office activity: it aims to open the ‘black box’ of lobbying to restore trust, but in doing so it forces trade‑offs between useful disclosure and client confidentiality, between a strong, independent investigatory regulator and a Minister’s supervisory power, and between deterring improper revolving‑door conduct and unduly restricting the private sector livelihoods of former officials.

The bill stitches together definitional breadth with detailed reporting and criminal sanctions, but that combination creates practical ambiguities. The phrase ‘with, or in relation to, a Government representative’ and the broad definition of ‘influence’ leave room for divergent interpretations about routine advice, indirect communications and multi‑channel advocacy.

Exemptions (for committee communications, constituents, grassroots activity and certain professional work) help, but regulators will need tight guidance to differentiate acceptable contact from regulated lobbying. The third‑party client carve‑out for pending transactions recognises commercial sensitivity, but it also creates a pathway for frequent redactions: a lobbyist’s notice that disclosure could ‘reasonably be expected’ to cause speculation is fact‑sensitive and could be overused to shield large swathes of activity.

Structurally, the bill centralises enforcement in the National Anti‑Corruption Commissioner and grants robust investigatory powers by importing the NACC Act framework, which strengthens investigatory capacity but raises resource and priority questions for the Commissioner’s office. At the same time, the Minister’s explicit power to direct registration decisions introduces a tension between operational independence and ministerial oversight; the statutory notice-and‑response steps blunt arbitrariness but do not remove the possibility of politically coloured interventions.

Implementation will also hinge on rule‑making and guidance: the Act defers key definitions (what counts as ‘low value’ hospitality, precise formats for returns, technical boundaries of 'close relationship') to rules, which determines how burdensome compliance will be in practice.
