Australia’s minimum fuel reserves would more than double to give the country more breathing space in future fuel shocks under new rules the Coalition wants adopted from next year.

Opposition Leader Angus Taylor will also pledge to spend $800 million to increase storage capacity for fuel on Australian shores when he unveils a new fuel security plan on Tuesday.

Australia currently has about 44 days of petrol, 33 days of diesel, and 30 days of aviation fuel, according to government data released on Sunday.

All of these are above the minimum stockholding obligations — and in the case of petrol, more than double the legal requirement.

This minimum stockholding is fuel kept in reserve, beyond what is held at service stations or in storage after purchase by farmers, miners and other users.

Mr Taylor wants to lift the baseline stockholding levels from January 2027 to lock in the current average as the new minimum.

Under his plan, the government would then work with industry on a roadmap to continue lifting stockholdings until the minimum was more than doubled to 60 days, which the Coalition believes can happen by 2030.

On top of this, he wants to add 1 billion litres of storage facilities.

Currently, there are almost 5.8 billion litres of fuel stored in reserves.

Mr Taylor describes it as a practical plan to make sure Australia never runs out of fuel.

“If fuel stops, Australia stops. It’s that simple. Trucks don’t move, supermarkets don’t stock, businesses shut their doors,” he said.

“This is about protecting Australians’ way of life and restoring their standard of living. You don’t do that with talk. You do it with action.”

Nationals leader Matt Canavan said beefing up reserves would mean “we are not relying on overseas supply lines that can be cut overnight”.

Coalition modelling suggests increasing the level of reserves – which requires building more storage – would increase the price of petrol by about 1c/L, but it sees this as “prudent insurance” to shield the country from further shocks like the one happening now.

Iran all but closed the Strait of Hormuz in response to the US and Israel bombing campaign that started at the end of February, which choked a crucial shipping route for about 20 per cent of the world’s oil supplies.

The Government says it’s now secured fuel supplies for Australia through to early June.

At the moment, there are 58 ships with fuel en route to Australia, several of which are expected to dock this week.

Foreign Minister Penny Wong left on Monday for talks with counterparts in Japan, China and Korea with a heavy focus on continuing to secure fuel supplies.

The government is concerned about reports that as the pre-war crude oil supplies that passed through the Strait come to an end, some Asian countries are looking to impose export controls on refined fuels.

“We know that our energy security is shared. We know that we rely on countries of the region to supply us with liquid fuels, with diesel, with petrol and of course with fertiliser. And we also know Australia is a reliable energy provider and a reliable provider of food to our region,” Senator Wong said ahead of leaving.

“We want to remain a reliable supplier and we want to see Australia prioritised when it comes to diesel, petrol and fertiliser. That requires face-to-face engagement.”
