Perth-based petrol retailer Burk Fuel faces a civil prosecution in the Western Australia Supreme Court after consumer watchdogs alleged the chain sold standard unleaded 91 fuel while charging motorists for higher-grade 95 and 98 octane products.
- Legal Exposure: Western Australia’s Consumer Protection Agency initiated Supreme Court proceedings on Monday, November 9, 2026, targeting 14 stations operated by Burk Fuel.
- The Allegations: Independent laboratory testing of fuel samples collected between July 2025 and February 2026 allegedly revealed that premium gasoline pumps contained standard 91 octane fuel.
- Corporate Response: Burk Fuel stated an intention to defend the proceedings while maintaining normal operations across its network, alongside a separate legal dispute with commercial landlords.
The consumer watchdog commenced legal action following a nearly year-long investigation into the discount fuel provider. Consumer Protection Commissioner Trish Blake announced the filing on Monday, outlining allegations that span eight stations representing 95 octane fuel and 10 stations representing 98 octane fuel, with overlap across 14 total sites.
Authorities launched the inquiry after receiving a tip-off from a whistleblower who contacted 102.5 ABC Perth. Investigators subsequently deployed secret shoppers and commissioned independent testing from accredited laboratories. According to Blake, testing on each occasion showed the fuel measured at 91 octane rather than the advertised higher grades.
When authorities publicly announced the investigation in April, Burk Fuel strenuously denied the allegations. The company maintained that it utilized reputable suppliers and subjected its inventory to regular testing. The retailer now faces court proceedings and potential orders for consumer compensation alongside significant financial penalties.
Burk Fuel operates as a discount competitor in the Western Australian market, frequently undercutting rival service stations by up to 10 cents per litre. Blake noted that this pricing model was likely facilitated by the alleged practice of substituting premium grades with standard unleaded product.
Higher-octane fuels are specifically recommended or required for high-performance vehicles, creating a direct financial and mechanical disparity for motorists. Blake emphasized the breach of trust inherent in the trade, noting that consumers lack the independent ability to inspect fuel quality at the pump and must rely entirely on trader integrity.
In contrast to the findings at Burk Fuel locations, Blake reported that random sampling of other retail fuel traders across Western Australia confirmed their products matched promotional labeling. Blake confirmed contact regarding Burk Fuel service stations.
Burk Fuel is currently involved in a separate Supreme Court action against corporate landlords attempting to terminate leases across five regional sites, including locations in Arthur River, Williams, Carrabin, Camillo, and Beaufort River.
Court documents show the company lodged a writ in July after landlords allegedly seized the Arthur River site over claimed structural damage. Burk Fuel continues to fight the lease terminations in court while maintaining that all other retail sites operate as usual.

As the legal proceedings progress in the Supreme Court, the exact magnitude of affected consumers and financial damages remains undetermined. Burk Fuel has declined further public comment while the matter remains before the judiciary.
