The Albanese Government has moved to pre-empt potential spikes in petrol and diesel prices, announcing on September 19, 2026, an extension of the temporary reduction in the Minimum Stockholding Obligation (MSO) for fuel suppliers. This measure, which allows companies to hold 20% less petrol and diesel in reserve, will now remain in effect until January 31, 2027. The decision aims to maintain flexibility in the domestic market and ensure consistent supply, particularly for regional Australia during the grain harvest and upcoming summer holiday travel season.
The extension comes amidst a volatile global oil market, which has already seen Australian fuel prices climb. Average unleaded petrol prices in major East Coast cities are currently around AUD 2.10 to AUD 2.30 per litre, with some forecasts suggesting potential increases of 20-30 cents per litre in the coming weeks due to escalating international conflicts.
Why the Extension Matters for Your Wallet
The Minimum Stockholding Obligation requires fuel importers and refiners to hold a certain amount of fuel in reserve. By temporarily reducing this obligation, the government provides suppliers with greater operational flexibility, allowing them to prioritise bringing fuel into the domestic market rather than stockpiling. This is a strategic move to mitigate supply chain pressures and help prevent prices from rising even higher.
“The Albanese Government is taking practical action to help keep fuel available when and where Australians need it, particularly during busy periods like harvest and the summer holidays,” a government spokesperson stated. “This extension keeps fuel reserves in good supply, while maintaining flexibility in the local market.”
The policy directly addresses concerns about fuel availability and price stability. While it doesn’t directly cap prices, a more fluid supply chain can help temper upward price movements that might otherwise occur due to shortages or bottlenecks, especially during periods of high demand.
Current Fuel Price Landscape
Australians have faced significant increases at the pump throughout 2026. Data from September 14, 2026, indicated an average national gasoline price of AUD 2.13 per litre, a notable rise from AUD 1.98 per litre just one month prior. This trend has been influenced by global crude oil benchmarks and the full restoration of the federal fuel excise, which returned to 53.7 cents per litre in August 2026 after temporary relief expired.

|---|---|---|---|
| Unleaded 95 | AUD 2.13 | +7.6% | +27.5% |

These price movements underscore the vulnerability of Australian consumers to international market forces. The government’s MSO extension is a reactive measure to these pressures, aiming to smooth out potential volatility in the short term.
Looking Ahead: Summer Demand and Energy Alternatives
With the summer holidays approaching, demand for petrol and diesel is expected to surge as Australians embark on road trips. The extension of the MSO reduction is specifically designed to support this increased demand, particularly in regional areas where harvest operations also drive significant fuel consumption.
For those seeking to mitigate the impact of rising fuel costs, the shift towards electric vehicles (EVs) continues to offer an alternative. While the upfront cost of EVs can be higher, operational savings on fuel and maintenance are a significant draw.

While the MSO extension provides a degree of reassurance for motorists heading into the busiest travel period, the underlying pressures of global oil prices and domestic excise rates mean fuel costs are likely to remain a significant consideration for Australian households and businesses into early 2027. The government’s focus on fuel security highlights the ongoing challenges in managing energy costs across the board.
