Workplace fraud rarely begins with a dramatic discovery. More often, it appears as a small irregularity: an invoice that looks slightly different, an unexplained adjustment to a record, a manager insisting that a payment bypass normal approval, or a colleague who becomes defensive when asked a routine question.
Individually, these events may have an innocent explanation. When they form a pattern, however, they can signal deliberate misconduct.
Employees are often the first people in a position to notice these warning signs. They work directly with invoices, customer accounts, payroll systems, inventory, procurement processes and confidential information. Their day-to-day knowledge helps them recognise when something does not fit normal business practice.
That awareness matters. The National Anti-Scam Centre’s 2025 data recorded 481,523 scam reports and $2.18 billion in combined reported losses across participating Australian organisations. Payment-redirection scams alone accounted for $166.8 million in reported losses. While external scams are not the same as occupational fraud, the figures show how easily deception, stolen credentials and manipulated payments can cause serious financial harm.
Recognising a red flag does not mean accusing someone. It means noticing an unusual event, checking it through the proper process and reporting a genuine concern before further damage occurs.
What Is Workplace Fraud?
Workplace fraud is intentional deception carried out to obtain an unauthorised benefit or cause another party a loss. It can be committed by an employee, manager, executive, contractor, supplier, customer or external criminal working with someone inside the organisation.
It may involve stealing money or property, but the behaviour can be broader than direct theft. Falsifying records, concealing conflicts of interest, creating fictitious suppliers, manipulating sales figures and misusing confidential information may also constitute fraud.
Common forms include payroll fraud, expense fraud, procurement fraud, invoice manipulation, asset theft, bribery, corruption, financial-statement fraud and cyber-enabled payment fraud.
Errors should not automatically be treated as fraud. A payroll officer may enter the wrong amount, or a supplier may accidentally send an outdated bank account number. Fraud generally involves deliberate dishonesty rather than an accidental mistake.
The practical challenge is that intent is rarely visible at first. Employees should therefore focus on observable facts and patterns rather than trying to decide whether someone is guilty.
Why Employee Awareness Is So Important
Fraudsters often exploit ordinary business habits. They depend on people being busy, trusting a familiar name or feeling uncomfortable about challenging senior staff.
A finance employee may receive what appears to be an urgent message from the managing director. A warehouse worker may notice stock disappearing in unusually small amounts. A junior administrator may see the same manager repeatedly approving a relative’s business as a supplier.
Each employee sees only one part of the organisation. When people understand fraud indicators and feel safe raising concerns, those separate observations can reveal a much larger problem.
Global occupational-fraud research consistently identifies tips as an important way misconduct is detected. This makes employees part of an organisation’s early-warning system, although they should never be expected to investigate suspected fraud themselves.
An effective workplace supports questioning without treating every question as an allegation. “Can we verify these bank details?” is a sensible control, not an expression of distrust.
Financial and Accounting Red Flags
Unexplained or Repeated Adjustments
Frequent journal adjustments, refunds, credit notes, write-offs or reversals deserve attention when there is no clear supporting reason.
A single correction may be routine. A pattern of adjustments made by the same person, particularly near the end of a reporting period, can indicate that records are being manipulated to hide shortages or improve reported results.
Other warning signs include round-dollar entries, vague descriptions, missing documents and transactions processed outside normal hours.
Missing or Altered Supporting Documents
Legitimate transactions usually leave a clear trail. Purchase orders, contracts, receipts, delivery confirmations and approvals should support the payment.
Be alert when documents are repeatedly missing, appear to have been edited, contain inconsistent fonts or dates, or do not match the goods and services received. Photocopied receipts used several times and invoices with vague descriptions such as “consulting services” may also require verification.
The concern becomes stronger when the person responsible refuses to provide original documents or pressures others to process the transaction anyway.
Unusual Refunds and Customer Credits
Employees working in retail, hospitality, healthcare or customer service should watch for refunds without a customer present, credits processed to the same card, cancelled sales after a shift closes, or returns without corresponding goods.
A supervisor who regularly authorises their own exceptions may be exploiting weak controls. The records may appear individually valid while the overall pattern shows something different.
Payroll and Timesheet Fraud Indicators
Payroll fraud can continue for months because payments are automated and employees assume payroll records have already been verified.
A common warning sign is a “ghost employee”—a person listed on the payroll who does not genuinely work for the organisation. Other indicators include duplicate bank account details, unexplained overtime, altered leave balances and payments continuing after someone has left.
Timesheet fraud may involve claiming hours not worked, asking another employee to clock in, or approving inflated overtime. Managers can also manipulate allowances, commissions or performance bonuses.
Consider a team in which one employee regularly claims weekend overtime, yet colleagues never see that person working and system records show no weekend activity. That mismatch does not prove fraud, but it provides a reasonable basis for payroll or management to review the claim.
Employees should not access confidential payroll information without authority. They should report irregularities observed through their normal duties rather than searching for evidence themselves.
Procurement and Supplier Red Flags
A Suspiciously Close Supplier Relationship
Procurement fraud often involves an undisclosed relationship between an employee and a supplier. The employee may direct work to a friend, relative or business in which they hold a financial interest.
Warning signs include unusual loyalty to one supplier, resistance to competitive quotes, repeated acceptance of poor performance, or a staff member communicating with a vendor through personal accounts.
A conflict of interest is not always fraud. It becomes dangerous when it is concealed or influences a business decision for personal benefit.
Newly Created or Unverifiable Suppliers
A fictitious supplier may have a generic name, limited online presence, residential address or bank account connected to an employee. Its invoices may lack a valid Australian Business Number or contain contact details shared with another vendor.
Employees can check an Australian Business Number using the official ABN Lookup service. However, having a valid ABN does not prove that an invoice or bank account is genuine. Verification should still follow the organisation’s supplier-onboarding process.
Be cautious if someone wants to add a new vendor urgently, bypass due diligence or make a substantial first payment before goods arrive.
Identical Bids or Unusual Tender Patterns
Procurement staff may notice competing quotes with identical wording, formatting errors or pricing structures. This can indicate that bids were prepared together or that genuine competition did not occur.
Other signs include the same group of suppliers taking turns winning contracts, losing bidders becoming subcontractors, or specifications being written so narrowly that only one preferred supplier can qualify.
These patterns may point to collusion, favouritism or bid manipulation and should be reviewed by an appropriately independent person.
Gifts and Hospitality That Influence Decisions
A modest gift may be allowed under an organisation’s policy. Secret commissions, cash, expensive travel or repeated entertainment are different.
The key question is whether the benefit could influence—or appear to influence—a business decision. Gifts offered during a tender, contract renewal or dispute deserve particular caution.
Employees should declare gifts, hospitality and conflicts according to workplace policy. Transparency protects both the employee and the organisation.
Behavioural Red Flags
Behaviour alone cannot establish fraud. Financial pressure, stress, illness or personal circumstances may explain a change in conduct. Behavioural warning signs should therefore be considered carefully and never used to stereotype or publicly accuse a colleague.
Relevant indicators can include:
-
Refusing to take annual leave or allow another employee to perform a task
-
Becoming unusually defensive about routine checks or audits
-
Insisting on controlling a transaction from beginning to end
-
Keeping passwords secret from authorised team members or using shared accounts
-
Developing an unexplained close relationship with a supplier or customer
-
Frequently overriding controls because a transaction is supposedly urgent
-
Displaying lifestyle changes that appear inconsistent with known income
-
Removing documents, working unusual hours or accessing records outside normal responsibilities
The strongest warning sign is often not the behaviour itself but its connection to a process weakness. An employee who never takes leave may simply enjoy working. If that person also controls supplier creation, invoice approval and payment reconciliation, the lack of oversight becomes much more significant.
Digital and Business Email Fraud Red Flags
Cyber-enabled fraud can appear to come from a trusted colleague, customer or supplier. Criminals may compromise a real email account or create an address that differs by only one character.
The Australian Signals Directorate’s Australian Cyber Security Centre provides guidance for businesses responding to cyber threats. Employees should be particularly cautious when a message requests new bank details, secrecy, urgent payment, gift cards, login credentials or a multi-factor authentication code.
A typical payment-redirection attempt may arrive during a genuine conversation with a supplier. The writing style and invoice appear familiar because the criminal has been monitoring the email account. Only the bank details have changed.
Verify financial changes using a trusted telephone number already held on file—not the number included in the suspicious email. Never rely solely on a reply to the same email chain.
Other digital indicators include unexpected password-reset messages, unfamiliar login alerts, email rules that automatically forward messages, invoices sent from lookalike domains and a senior executive requesting an unusual payment while supposedly unavailable.
The National Anti-Scam Centre reported that phishing was the most frequently reported scam to Scamwatch in 2025, with 65,361 reports. This reinforces why every employee—not only the IT team—needs to pause before acting on unusual digital requests.
Inventory and Asset Misuse
Missing stock is sometimes dismissed as an administrative issue, particularly when each item has a relatively low value. Repeated discrepancies can nevertheless indicate theft or manipulation.
Employees may notice inventory counts that never match records, damaged goods being written off but not destroyed, tools disappearing after particular shifts, or assets leaving the premises without authorisation.
False write-offs are especially concerning. Someone may mark usable equipment as damaged and later remove or sell it. Others may create false dispatch records to conceal stock leaving the warehouse.
Company resources can also be misused without physically leaving the workplace. Examples include using fuel cards for private vehicles, diverting customer leads, using paid staff time for a personal business or downloading confidential data before resignation.
Sales, Performance and Record Manipulation
Pressure to meet targets can encourage employees or managers to manipulate results. Sales may be recorded before contracts are finalised, customer signatures may be altered, or unsuitable products may be sold to generate commissions.
A sales figure that looks unusually strong is not itself suspicious. Concerns arise when results cannot be reconciled with contracts, customer activity, delivery records or cash received.
Employees may also encounter instructions to backdate documents, hide complaints, change inspection results or omit information from a report. “Everyone does it” and “we will correct it next month” are not acceptable reasons to falsify a business record.
Record manipulation can harm customers, investors, regulators and other employees. It may also conceal safety, privacy or service-quality failures rather than direct financial theft.
What Should You Do If You Notice a Red Flag?
The safest response is calm, factual and consistent with workplace procedure. Do not confront the suspected person, make public accusations or attempt to run your own investigation.
Take the following steps:
-
Pause the transaction if your authority allows it, particularly when payment details have changed or a request bypasses controls.
-
Record what you observed, including dates, transaction references and the exact communication involved.
-
Preserve information you are legitimately authorised to access. Do not remove original records or search private accounts.
-
Report the concern through your manager, fraud-control team, internal audit, compliance function or whistleblower channel.
-
Keep the matter confidential and avoid discussing it with uninvolved colleagues.
-
If money may have been transferred following a cyber incident, contact the organisation’s bank and security team immediately.
-
Follow any instructions from authorised investigators and distinguish clearly between facts, assumptions and second-hand information.
Good reporting sounds like this: “Invoice 4817 contains bank details different from those in the supplier master record. The email requesting the change arrived at 2:15 pm and asked for payment today.”
It should not sound like this: “The accounts manager is definitely stealing money.”
The first statement gives decision-makers verifiable information. The second makes an allegation before the facts have been established.
Whistleblower Protection in Australia
Australia has several whistleblower frameworks, and the protection available depends on the organisation, the person making the disclosure, the subject of the report and the recipient.
Eligible whistleblowers reporting certain corporate misconduct may receive protections under the Corporations Act. These can include confidentiality protections, protection from certain liability and safeguards against victimisation. The Australian Securities and Investments Commission explains who may qualify, what types of matters can be disclosed and which recipients are eligible.
Different arrangements apply in the public sector. Tax-related disclosures may also fall under separate rules. Employees should consult their organisation’s whistleblower policy and obtain independent legal advice if the circumstances are serious or unclear.
A workplace policy cannot remove rights provided by law. At the same time, not every workplace complaint qualifies as a protected whistleblower disclosure. Personal employment grievances may be treated differently unless they involve broader misconduct or another protected issue.
Where Can Workplace Fraud Be Reported?
Internal reporting is often the quickest route when the organisation has a credible and independent process. Depending on the conduct, external reporting options may also include ASIC, the Australian Taxation Office, state or territory police, or the organisation’s sector regulator.
Cybercrime can be reported through the Australian Government’s ReportCyber service. Scams can be reported to Scamwatch, although Scamwatch does not investigate every individual report or recover funds.
If a fraudulent transfer has occurred, the organisation should contact its financial institution immediately. Speed matters because banks may have a better chance of stopping or tracing a payment when notified early.
In an emergency or where personal safety is at risk, contact police. Employees who are uncertain about their legal position should consider independent legal advice before disclosing confidential information outside authorised channels.
Building a Fraud-Resistant Workplace
Fraud prevention is strongest when controls and culture support each other. Policies alone will not help if employees fear retaliation or senior staff routinely ignore them.
Organisations should separate key financial duties, require independent verification of bank-detail changes, limit system access, review unusual transactions and conduct regular reconciliations. Employees should receive practical training based on the situations they actually encounter.
Leaders also need to model the expected behaviour. If a director becomes angry when finance verifies an urgent payment, employees learn that status matters more than controls. If the director welcomes the check, employees learn that fraud prevention is everyone’s responsibility.
Training such as Fraud Awareness and Prevention in the Workplace can help employees distinguish a genuine warning sign from a simple mistake, respond safely and understand why reporting procedures matter.
To strengthen fraud awareness across your organisation, explore practical workplace compliance training from Australian Compliance Training. Give employees the confidence to stop, check and report suspicious activity before a small irregularity becomes a serious loss.
