Public funding of election campaigns explained

The short answer

Public funding of election campaigns explained

Australian federal election campaigns can receive public funding under Part XX of the Commonwealth Electoral Act 1918. Political parties, candidates and Senate groups that meet eligibility thresholds and have incurred electoral expenditure are entitled to claim election funding from the Commonwealth. The amount is calculated by reference to a prescribed rate per eligible vote received, but funding is not simply an automatic payment of that amount. It is a reimbursement of verified electoral expenditure: a candidate or party must actually spend the money on campaign costs and can only claim up to the amount of electoral expenditure incurred or the amount calculated by multiplying eligible votes by the funding rate, whichever is less. The funding rate is indexed and published by the Australian Electoral Commission. Unendorsed candidates and Senate groups must receive at least four per cent of the formal first preference vote in their state or territory to be eligible. The system is designed to support democratic participation by reducing candidates' dependence on private donations, while requiring accountability through the financial disclosure scheme.

This guide uses public electoral and parliamentary records. A party or candidate statement establishes what that actor says; it does not independently establish that the statement is true.

The useful question is not only “what is the rule?” but also “who administers it, which document controls it, and when might it change?” That distinction prevents an accurate general explanation from becoming wrong advice in a particular election, chamber or policy setting.

How public funding is calculated

Public election funding is calculated under Division 3 of Part XX of the Commonwealth Electoral Act 1918. The starting point is the number of eligible votes: for a candidate endorsed by a registered political party, every formal first preference vote received counts. For Senate groups and unendorsed candidates, the four per cent threshold applies. The number of eligible first preference votes is multiplied by the current funding rate, which is indexed every six months in line with the Consumer Price Index. As of 2026, the rate is approximately 3.30 dollars per eligible vote, though the AEC publishes the exact rate. The resulting amount is the maximum the candidate or party is entitled to claim. However public funding is a reimbursement, not an automatic payment. The candidate or party must have incurred electoral expenditure equal to or greater than the claimed amount, and must lodge a claim with the AEC within 20 weeks after polling day. The claim must detail the electoral expenditure incurred, and the AEC may audit the claim before making payment.

Eligibility thresholds and the four per cent rule

Not all candidates are eligible for public funding. Candidates endorsed by a registered political party are automatically eligible. Candidates who are not endorsed by a registered party, and Senate groups that are not endorsed, must receive at least four per cent of the formal first preference votes in their state, territory or division to qualify. This threshold is designed to prevent frivolous or vexatious candidacies from accessing public funds while ensuring that legitimate independent and minor party candidates with demonstrable public support can participate in the scheme. The threshold operates at the Senate group level for the Senate and at the division level for the House of Representatives. Candidates who fail to reach this threshold receive no public funding, regardless of their electoral expenditure. The four per cent threshold has been the subject of political debate, with some arguing it is too high and others arguing the scheme should be restricted to candidates who achieve a higher level of electoral support.

Electoral expenditure: what can be claimed

Electoral expenditure is defined in the Commonwealth Electoral Act and includes a wide range of campaign spending. This covers advertising on broadcast media, in print and online, production of campaign materials such as leaflets and how-to-vote cards, direct mailing, opinion polling and research undertaken for the election campaign, and the cost of campaign staff and offices. Expenditure on travel, accommodation and other logistics related to the campaign is also included. The definition is broad but certain costs are excluded, such as the candidate's nomination deposit and expenditure on activities that are not for the dominant purpose of influencing voting at the election. Capital expenditure on assets that retain value after the election, such as computer equipment, may be apportioned. Political parties and candidates must maintain detailed records of their electoral expenditure and must be prepared to substantiate their claims to the AEC. The AEC's guidelines provide further detail on what can and cannot be included in a claim.

The financial disclosure scheme and transparency

Public funding is linked to the financial disclosure scheme under Part XX of the Act, which is administered by the AEC. Political parties, significant third parties, associated entities, members of Parliament, senators, candidates and Senate groups, and donors who contribute above the disclosure threshold must lodge annual or election returns with the AEC. These returns are published on the AEC's Transparency Register, which allows the public to see the sources of political donations and the nature of political expenditure. The purpose of the disclosure scheme is to increase transparency and inform the public about the financial dealings of political participants. From 1 January 2027, significant changes to the funding and disclosure scheme come into effect, including new registration requirements, new disclosure obligations and changes to the public funding model. The transitional rules from 1 July 2026 apply to entities with obligations under the existing scheme as they move to the new framework.

How public funding differs from donations

Public funding and political donations are distinct sources of campaign finance. Public funding comes from Commonwealth revenue and is paid under statutory rules that apply equally to all eligible candidates and parties. Political donations come from private sources, including individuals, corporations, unions and other organisations. Donations above the disclosure threshold, currently approximately 16,900 dollars, must be disclosed to the AEC, along with the donor's details. Some categories of donations, such as those from foreign sources, are restricted or prohibited. The public funding system is sometimes described as reducing the influence of large private donors by providing a baseline of public support, but the relationship between public funding and private donations is the subject of ongoing policy debate. Candidates and parties may receive both public funding and private donations, and the total campaign expenditure of major parties typically exceeds the amount they receive in public funding, meaning private fundraising remains essential for most election campaigns.

State and territory public funding schemes

Several states and territories operate their own public funding schemes for state elections, with rules that differ from the federal scheme. New South Wales, Victoria, Queensland, Western Australia and South Australia all have some form of public funding, though the rates, eligibility thresholds and conditions vary. The ACT operates an expenditure cap system combined with public funding. Some jurisdictions have introduced real-time disclosure requirements or bans on certain types of donations that go beyond the federal scheme. Candidates who stand in both federal and state elections are subject to the respective rules of each jurisdiction. The interaction between federal and state funding schemes can be complex, particularly where party units operate across both levels of government. Public funding of local government elections is less common and varies between states.
