Australia to change fuel quality standards to boost supply

In response, Energy Minister Chris Bowen said one of the country's top refiners, Ampol, has agreed to redirect supply to regions experiencing shortages and the wholesale market.

"This will allow around 100 million litres a month of new petrol supply that would otherwise have been exported to be blended instead into Australian domestic supply," Bowen said.

Farmers, fishers and regional communities were a priority for support, he said.

Oil prices on Thursday topped $100 a barrel again after Iranian attacks on shipping effectively closed the Strait of Hormuz in response to the US-Israeli strikes that killed Supreme Leader Ayatollah Ali Khamenei.

Australia's government has blamed price-gouging by retailers for rising domestic costs of fuel.

Treasurer Jim Chalmers said that while the country has "enough fuel", there were supply issues, particularly in rural areas.

"This conflict in the Middle East is already putting additional pressure on Australians, we understand that," he told national broadcaster ABC.

The International Energy Agency said on Wednesday its member countries would unlock 400 million barrels of oil from their reserves to ease the impact of the Middle East war -- the biggest such release ever.

The coordinated release was the sixth in the history of the organisation, which was created to coordinate responses to major supply disruptions after the 1973 oil crisis.

Australia, an IEA member, has said its contribution will be focused on the domestic market.
