Key Points
Diesel prices hit $2.70-$2.80 per litre, up from $2.30 six weeks ago.
US-Iran conflict and expired fuel excise discount drove July-August surge.
Traveller fuel costs doubled from $23 to $50 per 100 kilometres.
Import costs now 23% above six-week baseline, expected to stay elevated.
Diesel prices in Australia have climbed to $2.70 to $2.80 per litre, forcing full-time travellers and regional communities to slash their budgets and limit their movements. The surge stems from escalating US-Iran tensions, the expiration of the government’s fuel excise discount in July, and a weakening Australian dollar. Brent crude has jumped 8.3% in a week to US$107.03 per barrel, with import costs now 23% above levels from six weeks ago.
How much fuel costs have risen
Diesel prices have hit $2.70 to $2.80 per litre across Australia. Seamus Campbell, a 70-year-old full-time traveller, said his fuel costs per 100 kilometres have doubled from $23 to $50. A full tank of diesel now costs him up to $500. Kate Irwin and her husband spent $5,260.85 filling their Landcruiser with diesel on a 10,000-kilometre caravan trip from Brisbane to central Australia.
Why prices jumped in July and August
Fuel prices began climbing again in July and early August after two events: the re-escalation of the US-Iran conflict and the expiration of the government’s fuel excise discount. Fuel prices have soared 50% since the start of the US-Iran conflict, putting strain on households globally. Brent crude climbed 8.3% over the past week to US$107.03 per barrel, while the Australian dollar weakened 1.6% against the US dollar, lifting the local cost of imported fuel.
Who is being hit hardest
Full-time travellers and digital nomads have no option but to absorb the price sting, unlike commuters who can use public transport or rideshares. Regional Australia is particularly exposed because petrol stations are far apart and residents cannot easily switch to alternatives. Campbell said the cost of a trip to Perth will now run him about $2,000, forcing him to reconsider his travel plans and stay in closer areas.
What comes next for prices
Petrol import costs are currently 23% above where they were six weeks ago, and the price floor has risen permanently. Wholesale increases take 10 to 14 days to reach the bowser, meaning pump prices will continue climbing over the next two weeks. Prices are expected to remain elevated for the foreseeable future, with each price peak and trough higher than historical averages.
Final Thoughts
Australian fuel prices are now locked at elevated levels due to global supply disruptions and currency weakness. Travellers and regional communities face permanent budget pressures unless international tensions ease or the government intervenes with new relief measures.
