Diesel vs. Petrol: Why One Fuel is Still Hurting Your Wallet More Than the Other (Medium, Online)

Press/Media: Expert Comment

Description

Quoted in a explainer on the divergence between petrol and diesel prices following the halving of the fuel excise, identifying diesel rather than petrol as the locus of economic pain. The quotation anchors the article's concluding argument that the excise cut, applied equally across both fuels, was overpowered in the diesel market by supply-side shock and inelastic demand.

Subject

    DescriptionThis explainer examines why Australian petrol prices fell below $2 per litre following the halving of the fuel excise while diesel remained near $3, attributing the divergence to differences in price elasticity of demand. It argues that household petrol demand adjusts readily through deferred travel and carpooling, whereas diesel demand is structurally inelastic because freight, agriculture and mining cannot reduce consumption in response to price. The piece further identifies supply-side and structural asymmetries: diesel prices reference the Singapore Gasoil benchmark, which rose considerably more than Mogas 95 following the conflict; Australia consumes roughly 30 billion litres of diesel annually against domestic refining of approximately 4 billion; and roughly two-thirds of diesel volume moves through long-term commercial contracts rather than a competitive retail market, weakening pressure to pass through tax relief. Dr Lurion De Mello is quoted identifying diesel rather than petrol as the point of economic pain, supporting the article's conclusion that the excise reduction was uniform in design but uneven in effect.

    Two things worth weighing before you log this one. First, it's a self-published Medium post rather than an edited outlet, and your quotation appears to be lifted from other coverage rather than given directly — so it may sit better as an "additional pickup" note attached to whichever interview it derives from, if you can identify it, than as a standalone media item. Second, the substantive argument here maps closely onto your diesel dependency paper: inelastic demand, the 30bn/4bn consumption-to-refining gap, and Gasoil-linked pricing are all mechanisms you've been developing. That makes the item useful as evidence of your framing circulating, even if the venue itself carries little weight.
