Australia relies on imports for an estimated 90 percent of its refined petroleum products, and Singapore is its largest single supplier.

Albanese said he would travel to Singapore from April 9-11 to discuss trade in "essential supplies" such as diesel and liquefied natural gas with Prime Minister Lawrence Wong.

"Together, we share concern over the situation in the Middle East, including the consequences for both of our nations," the Australian leader told reporters in Canberra.

"Australia is facing a more uncertain world, and therefore the certainty of those clear, close relationships is more important than ever."

Australia and Singapore committed in a joint statement last month to keep fuel flowing between both countries and to work together to strengthen energy supply chain resilience.

Service station outages of diesel and unleaded gasoline in Australia are falling, the government said.

A total 241 service stations across Australia -- three percent of the total -- had no diesel on Tuesday, while 141 had no gasoline.

The country has 29 days' worth of diesel, 39 days of petrol, and 30 days of jet fuel, said energy minister Chris Bowen, stressing that levels had remained "pretty static".

Last week, the government halved its fuel tax on petrol for three months to help alleviate rising costs for motorists and truck drivers.
