Fuel fraud may be becoming a bigger problem for Australian fleets, with new data suggesting suspicious fuel activity is increasing as economic pressures continue to affect households across the country.
Fleet analytics provider Roev has reported a significant rise in fuel-related anomalies detected across customer fleets, highlighting the growing importance of data analysis and telematics in identifying unusual behaviour before it becomes a major cost burden.
According to Robert Dietz, Co-founder and CEO at Roev, the company is seeing a noticeable increase in the number of fuel transactions being flagged for further investigation.
“When we pulled the data, we are seeing an increase in anomaly detection of about 28 to 31 per cent (in 2026),” Dietz said.
While not every anomaly represents fraud, the trend is raising questions about what may be driving the increase.
One possible explanation is the growing financial pressure facing many workers and households.
Scott Elkington, Marketing Manager at Webfleet, believes fleet operators should pay attention to the underlying conditions that often contribute to fraudulent behaviour.
“When we talk about fuel fraud, usually you look at the fraud triangle,” Elkington said. “Rationalisation, pressure and opportunity.”
The concept is well known among fraud investigators and risk professionals. The theory suggests that fraudulent behaviour becomes more likely when individuals experience financial or personal pressure, have the opportunity to commit the act, and can justify their actions to themselves.
Elkington said today’s economic environment creates many of those conditions.
“People’s needs change. We hear it in the media, like cost of living pressure, and fuel’s obviously a very large part of that,” he said.
The challenge for Fleet Managers is that fuel misuse often starts small and can be difficult to identify among thousands of legitimate transactions.
“They can rationalise it,” Elkington explained. “They think the business doesn’t really notice that much fuel out of how much they use. It’s only a little bit of money.”
For large organisations operating hundreds of vehicles, even small instances of misuse can add up quickly over time.
Traditionally, identifying these issues has required extensive auditing and manual review of fuel card transactions. However, advances in analytics and telematics are making the process significantly easier.
Importantly, Dietz stresses that anomaly detection does not automatically imply wrongdoing.
“We detect the anomalies, we don’t judge them,” he said. “We just call them out.”
In many cases, unusual fuel usage can be explained by operational changes, additional equipment, or even mechanical problems that reduce vehicle efficiency.
However, by identifying anomalies early, fleet managers can investigate and determine whether corrective action is required.
The technology is proving particularly valuable because it allows organisations to focus on the handful of transactions that deserve attention instead of reviewing thousands of routine fuel purchases.
For fleets already grappling with rising fuel costs, the financial benefits can be significant.
As fuel remains one of the largest operating expenses for most vehicle fleets, even small improvements in accountability and oversight can have a measurable impact on operating budgets.
The increase in fuel anomalies does not necessarily prove fuel fraud is rising. But it does suggest that behaviours previously hidden within large datasets are becoming easier to detect.
And as analytics platforms become more sophisticated, Fleet Managers may discover that some of their biggest cost-saving opportunities have been hiding in plain sight all along.
