The Coalition unveiled the Fuel Price Shield, a mechanism intended to automatically buffer consumers and businesses from fluctuations in international oil markets, with drivers expected to see lower prices at petrol stations. The Fuel Price Shield would trigger an automatic halving of fuel excise whenever the Brent crude two-week average closing price exceeds US$100 per barrel. Upon activation, the provision is projected to cut fuel levies by approximately 27 cents per litre, saving drivers roughly $15 on a standard fill-up. The 32-cent-per-litre road user charge on heavy vehicles would be reduced to zero, easing costs for freight operators while also lowering prices for consumers and businesses through flow-on effects. Opposition Leader Angus Taylor argued that increases in international oil prices tend to pass through rapidly to costs faced by households and businesses, adding that fuel is a basic necessity rather than an optional expense. Mr Taylor stated that fuel is a daily necessity for commuters, families, and business operators, and that a dedicated price mechanism — the Fuel Price Shield — would deliver automatic, time-limited relief whenever international oil markets drive costs higher. In the event of a worldwide oil price disruption, the levy adjusts downward on its own. When oil prices return to standard levels, the standard rate is reinstated, removing day-to-day political influence from the decision and providing households and businesses with greater predictability about future global oil price fluctuations; for a household filling an average tank, the proposed Fuel Price Shield would retain approximately $15 that would otherwise be collected as tax, while Nationals leader Matt Canavan noted that fuel costs carry a particularly pronounced burden outside metropolitan areas, where residents have limited alternatives to private vehicle use. Many residents commute considerable distances for employment, education, healthcare, and everyday shopping, while elevated petrol costs ripple through the broader economy. Shadow Minister for Infrastructure and Transport Bridget McKenzie stated that the Fuel Price Shield would offer protection to trucking operators, freight companies, and regional communities, adding that transport operators have no option to cease operations when petroleum costs rise. Senator McKenzie stated that fuel represents one of the transport industry's largest operating expenses, and that price volatility in global oil markets flows through the supply chain to retail shelves and small businesses, adding that the proposed Fuel Price Shield would provide the sector with a buffer against sudden international oil price movements, alongside a corresponding adjustment to the road user charge to ensure heavy vehicle operators receive equivalent consideration. Shadow Minister for Energy and Emissions Reduction Dan Tehan outlined the Fuel Price Shield policy, explaining that it would automatically reduce fuel excise and eliminate the heavy vehicle road user charge whenever the two-week average settlement price of Brent crude exceeded US$100 per barrel, while also noting that the policy aimed to insulate households and businesses from the effects of overseas oil price increases that Australia has no capacity to influence. Any modifications would take effect on the Monday following the designated trigger date. Under the scheme, the trigger conditions would remain in force until either the rolling eight-week average price of Brent crude dropped beneath US$100 per barrel or a period of three months had elapsed from the point of activation, whichever came first. The short-term fuel duty relief was set to lapse at that juncture unless authorities opted to prolong it after assessing prevailing international oil prices and broader market conditions. Under the proposal, the road user charge for heavy vehicles would be temporarily waived, delivering an added financial benefit to operators of trucks and buses on top of the excise duty cut. Under the proposed changes, the heavy vehicle road user charge would drop from 32.4 cents per litre to zero, enabling truck and bus operators to reclaim the full 26.85 cents per litre fuel excise through a Fuel Tax Credit, which may then be applied against their GST liability when submitting Business Activity Statements. According to modelling by the Coalition, the Fuel Price Shield would have been activated on just two occasions over the preceding five years, during periods of rising global oil prices in early 2022 and March 2026. In each of those two timeframes, the Fuel Price Shield would have been active for around six months and three months, respectively. The proposed mechanism would establish an established set of guidelines governing how authorities respond to oil price volatility, removing the need to devise ad hoc relief measures each time costs at the pump spike. Projections place the monthly expenditure of the measure at approximately $950 million when in effect. The policy applies only when oil prices reach unusually elevated levels and contains an automatic deactivation mechanism, meaning fuel excise revenue faces no lasting shortfall. Projections in the existing fiscal plan anticipate petroleum prices recovering to approximately US$80 per barrel by mid-2027. Under the Fuel Price Shield, the ACCC would be responsible for overseeing both wholesale and retail petrol pricing to verify that any reduction in fuel excise flows through to consumers at the bowser. The ACCC would oversee pricing, expenditure and profit margins throughout the fuel supply chain, while also working directly with wholesalers and retailers to ensure the excise cut was being passed on to consumers. Petrol and diesel sellers would be anticipated to transfer the complete levy decrease to consumers promptly as older inventory bought at the prior tax rate is drawn down. The ACCC tracked both wholesale and retail pricing movements during earlier fuel excise cuts, examining how reductions flowed through to the pump for end consumers, and a comparable oversight role is anticipated under the current arrangement. The Fuel Price Shield would form part of the Coalition's wider policy framework aimed at bolstering domestic fuel security and limiting vulnerability to international supply chain disruptions. Under the proposal, minimum fuel stockholding requirements would be more than doubled to 60 days for certain fuel types, alongside the establishment of an $800 million Australian Fuel Security Facility aimed at adding over one billion litres of new storage capacity, with diesel as the primary focus. The party has also pledged to launch a publicly accessible daily dashboard tracking fuel supply levels, channel investment into new and prospective refining capacity via the Fuel Security Services Payment, and reduce regulatory obstacles to boosting domestic fuel availability.
