Probity in Procurement: Rules, Roles and Red Flags

Tuesday, 1 September 2026

Key takeaways

Probity is proportionate. Finance is explicit that it should be helpful, inclusive, tailored and sensible, and that excessive process can itself damage value for money.
Conflicts do not have to be avoided at all costs. They have to be identified and managed, and the management has to be recorded.
A probity adviser and a probity auditor are different roles, and one cannot fix problems the other is meant to report on.
Sign off by an external probity expert does not transfer accountability. The entity still owns the process.

Probity in procurement means running a process that is fair, impartial and defensible, and being able to show it afterwards. Australia’s Department of Finance defines it as the evidence of ethical behaviour: complete and confirmed integrity, uprightness and honesty in a particular process.

What probity actually means

Start with an example. An evaluation panel scores five tenders, picks a winner and signs off. Eighteen months later an unsuccessful bidder asks how the decision was made. The panel members remember agreeing, but two of them never lodged conflict declarations, the scoring notes record conclusions instead of reasons, and one criterion in the evaluation report does not match the one advertised in the request documentation. Nobody did anything corrupt. The process simply cannot be demonstrated, which for an agency answering questions is close to the same position.

That gap is what probity fills. Australia’s Department of Finance describes probity as the evidence of ethical behaviour, defined as complete and confirmed integrity, uprightness and honesty in a particular process, and says it provides assurance to delegates, suppliers and the Commonwealth that a procurement was conducted in a manner that is fair, equitable and defensible. Ethics is the standard of behaviour expected. Probity is what can be shown afterwards.

The rules that apply

For Commonwealth entities the obligation sits inside the Commonwealth Procurement Rules. Under the efficient, effective, economical and ethical procurement provisions, ethical (applying ethics) relates to honesty, integrity, probity, diligence, fairness and consistency, and ethical behaviour identifies and manages conflicts of interests and does not make improper use of an individual’s position. Officials undertaking procurement must seek to prevent corrupt practices by recognising and dealing with actual, potential and perceived conflicts of interest, and by not accepting inappropriate gifts or hospitality.

The Finance probity principles add the operational detail. Officials must act in accordance with the Australian Public Service Values and Code of Conduct, must not accept hospitality, gifts or benefits from potential suppliers, and should avoid placing themselves where there is potential for claims of bias. All tenderers must be treated equitably, which Finance is careful to distinguish from equally. Confidentiality runs both ways, during the process and after it. And external probity specialists should only be appointed where justified by the nature of the procurement, not automatically because a tender happens to be open.

Two scope notes before applying any of this elsewhere. These rules bind Commonwealth entities, with corporate Commonwealth entities and state and territory agencies working to their own frameworks, though the underlying principles travel well. Private sector organisations have no equivalent rulebook, which does not stop an unsuccessful bidder forming a view about whether they were dealt with fairly.

Who does what: adviser, auditor and everyone else

The role distinctions matter more than they first appear, and Finance sets them out precisely. A process adviser advises on how the tender process should be structured to address probity issues, including drafting and monitoring a process plan. A probity adviser advises on issues as they arise during the process, often under a probity plan. A probity auditor reports an objective opinion on probity, generally after the process is complete.

The trap sits between the last two. Finance is explicit that a probity auditor should not be called in during a process to try to remedy problems, and that an expert engaged as an auditor must maintain independence and should not be offering advice to solve problems that arise. An organisation that hires one person to advise throughout and then sign off at the end has bought comfort, not assurance.

Two further points are easy to skip. Separation of duties means officials involved in evaluating tenders should not be the ones approving the spend. And the appointment of an external specialist, together with whatever sign offs they provide, does not remove the entity’s accountability for the process. The name on the report does not change whose decision it was.

Red flags worth watching for

Some warning signs recur often enough in audit reports to be worth naming. Declarations that were never collected, particularly from advisers and contractors rather than staff. A specification that reads as though it was written around one supplier’s product. Criteria that shift between the request documentation and the evaluation report. Evaluation notes that record conclusions but not reasons. Contact with a tenderer outside the process, especially at senior or ministerial level. An incumbent supplier who is also advising on the requirement. Gifts or hospitality accepted on the reasoning that everyone offers them, which Finance addresses directly and rejects.

The Home Affairs Permissions Capability procurement shows several of these together. An appropriate probity framework existed, with a probity plan and protocols in place before the request for tender was released. The ANAO nonetheless found that a complete and accurate conflict of interest register was not in place, with declarations missing from 15 per cent of individuals involved and from 38 per cent of those in the adviser category. Contrary to the probity plan and protocols, a minister met personnel from the preferred tenderer before contract negotiations began, and the meeting was not recorded in the probity register.

What happened after a complaint tells you more than the framework itself. A tenderer raised material concerns about the conduct and assessment of the tenders relating to an adviser’s conflict of interest. Home Affairs investigated appropriately, then gave the complainant the positive findings while leaving out the negative ones, which were that there was an actual conflict of interest amounting to a breach of the probity plan, and that it led to the termination of the adviser’s services. The framework worked. The response to what it surfaced did not.

Where probity itself becomes the problem

This is the part most probity guidance leaves out, and Finance says it plainly. Probity should not be used to justify avoiding reasonable discussion with potential suppliers during a tender, and value for money outcomes are best served by measures that do not exclude suppliers for inconsequential reasons. The guidance warns against arrangements that would exclude a tenderer for failing to attach a declaration when the process could allow a correction, or that prevent officials clarifying a response when clarification would help the committee understand what is being offered.

There is a drafting trap in the same territory. Finance advises against overusing the word must in tender rules, giving the example of a requirement that tenderers must supply resumes for all staff, which leaves an agency choosing between excluding a compliant bidder on a technicality or breaking its own rule. Conditions for participation should be minimal and objective, since each one is a rule you have committed to enforce.

What makes this difficult in practice is that the guidance calls for judgement, not compliance. Deciding whether a conflict can be managed or must remove someone, how much to say to a supplier who rings with a question, whether a process departure is fatal or fixable: all of it happens under time pressure with a deadline approaching. AG’s Legal & Policy Environment in Public Sector Procurement workshop works through those situations rather than the rules in the abstract.

If you want a single test for a process you are running now, ask whether someone outside it could reconstruct why the winner won, using only what is on the file.

Frequently asked questions

What is the difference between probity and ethics?

Ethics is the standard of behaviour expected of officials, covering honesty, integrity, fairness and consistency. Probity is the evidence of that behaviour in a specific process. An official can act ethically throughout and still have a probity problem if nothing on the file demonstrates it.

When do you need a probity adviser?

Only where the nature of the procurement justifies it. Finance lists relevant factors: high value, complex, unusual or contentious transactions, a history of controversy or litigation, high political sensitivity, markets where supplier grievances are more likely, and procurements where material conflicts of interest are expected. An open tender alone is not a reason.

Does a conflict of interest disqualify someone from a procurement?

Not necessarily. Conflicts should be eliminated where possible, but where that is not practical, such as when it would exclude expertise the process needs, management strategies are used instead. What matters is that the conflict is declared, assessed and managed, and that all of it is recorded.

Can officials talk to suppliers during a tender?

Yes, and Finance actively discourages treating probity as a reason not to. Officials can discuss current tenders with potential suppliers, with formality scaled to the risk of the procurement. Information useful to one supplier should generally be de-identified and shared with the others, and records kept of what was discussed.

Who is accountable if a probity adviser signs off and something goes wrong?

The entity. Sign off by an external probity expert cannot replace officials’ own accountabilities and obligations for the proper conduct of the procurement. Engaging an adviser buys expertise and an independent view, not a transfer of responsibility for the decision.
