Petrol and diesel prices are expected to increase in Australia as the country’s fuel tax relief ends, according to multiple reports. The change is linked to higher costs for both motorists and businesses that rely on road transport and diesel-powered operations. The reports also cite the escalation of the Iran conflict as an additional factor that could contribute to higher fuel prices, pointing to volatility in global fuel markets. Rising diesel costs are highlighted as particularly likely to affect sectors that depend heavily on diesel, including transport, farming, and mining. While the timing and size of any price increases are not specified in the excerpts provided, the overall expectation across the sources is consistent: the end of fuel tax relief removes a price-reducing measure, and heightened geopolitical tensions are expected to put upward pressure on fuel costs. The combined impact is described as likely to flow through to consumer fuel prices and to operational costs for industries that move goods and perform extraction and agricultural work.
