An Albanese government minister has dismissed mounting speculation that fuel rations will soon be enforced, amid rising tensions between Australia and US over the war in the Middle East. 

Multiple experts have warned that Australia could be forced to ration fuel within weeks, despite government assurances that supply has been extended. 

The speculation comes as US President Donald Trump launched a fresh attack on Australia for not joining the war against Iran.

'You know who else didn't help us? Australia didn't help us,' he said during a White House press briefing early Wednesday AEST.

'Japan didn't help us, Australia didn't help us, South Korea didn't help us!'

Sunrise Nat Barr grilled federal Attorney General Michelle Rowland about Trump's remarks and potential fuel rations when she appeared on the program on Tuesday morning.

'We are not considering that (rations). We are focused on security of supply,' Rowland said.

'Work has been done across industry and with our international partners to ensure that supply continues. 

'We did have security of supply until April that has now been extended to May.

'Every ship that was supposed to arrive has arrived, and we know that by shoring up arrangements with some of our closest trading partners in this area, including Japan and Singapore, they are the best ways that we can continue to ensure that we have that security of supply.'

Rowland issued a defiant message to Trump when she was asked whether the relationship between Australia and the US was on the rocks.

'The US is one of our longest and most important allies, but I will say this - Australia is not taking offensive action in this war,' she said.

'We will not be deploying troops. The actions that we have taken are defensive ones.

'I reiterate how important it is to continue to have a relationship with the US, but I think all of your viewers would agree that this war cannot end soon enough.'

'We will continue as a country to call for a de-escalation of this conflict. Your viewers are being impacted adversely by events on the other side of the world that they did not cause, and Australia did not cause.'

Barr also questioned whether the government can resolve the ongoing fuel crisis without support from the US.

Rowland said that the government was doing everything it can but acknowledged that Aussies are increasingly worried about the escalating impact of the war on them in during a cost-of-living crisis.

'You've got viewers tuning in today who are on school holidays, who are rightfully anxious about what is going on and the impact of the closure of the Strait of Hormuz and what is that what that's doing to our supply chains, to our agriculture stocks and so forth,' she said.

'But again, I think I should just reiterate that we cannot see an end to this conflict soon enough.'

The minister was unable to comment on whether Trump and Albanese had been in direct contact in recent weeks.

The last known communication between the pair was on March 10, when Trump publicly pleaded with Albanese to personally intervene to grant asylum to five players from Iranian women's team after the group escaped their Gold Coast hotel in a secret operation in a desperate bid to return home.

It sparked a late-night phone call, where Trump was personally assured by the Prime Minister that he 'was on it'. 

'I'll leave the Prime Minister to answer that for himself accurately,' Rowland said.

'I understand that communications with the White House are a matter of course, not only between our diplomats, but also between our senior officials.

'But what I will say is that there is constant contact between our officials, between our people in Washington and also at a ministerial level as well.'
