Live updates: Watch President Donald Trump's address to the US

Earlier today, Iran's foreign ministry said United States President Donald Trump's claim that the Iranian president had asked for a ceasefire was "false and baseless".

Trump made the claim on his Truth Social platform.

"Iran's New Regime President, much less Radicalized and far more intelligent than his predecessors, has just asked the United States of America for a CEASEFIRE!," Trump said, without specifying who he had spoken to.

Opposition leader Angus Taylor says Prime Minister Anthony Albanese's national address last night lacked clarity, saying: "We got hot air, we got nothing."

Speaking to the Today show on Thursday morning, Taylor said Australians heading off on their Easter holidays were seeking further information on the state of the fuel situation and has accused Albanese of wasting the "unusual" opportunity.

"What we need is clarity, confidence. Instead, what we've got is confusion," he said.

He urged transparency with the public about gaps in the supply chain and how they are going to be addressed. The government has issued persistent assurances that public supply levels remain steady, although demand has driven a spike in prices.

Taylor said it was unclear whether state or federal governments were leading the response, pointing to Western Australia, where Premier Roger Cook has declared a state of emergency.

"It’s extremely confused, and we're now getting responses from state premiers which are muddying the waters on where we’re going with all of this," he said.

Anthony Albanese's somewhat unusual decision to hold a televised national address to reiterate previously announced measures has some on the internet wondering why he didn't just send an email — but SBS Chief Political Correspondent Anna Henderson has other thoughts.

Before the announcement, speculation mounted that he might use his prime-time slot to announce troop deployment or fuel rationing; instead, the speech was light on policy and specific direction.

So, why did he decide to face the nation?

"Under President Trump’s leadership, the U.S. military is executing this mission with unmatched power and precision," it reads.

"From day one, the objectives have been clear and unwavering: obliterate Iran’s ballistic missile arsenal and production capability, annihilate its navy, sever its support for terrorist proxies, and ensure the world’s leading state sponsor of terrorism never acquires a nuclear weapon."

Several Trump administration officials are quoted outlining the objectives.

Trump earlier told the Reuters news agency the war with Iran would end fairly soon, though the US could return for "spot hits" if needed.

In his address, Reuters reported Trump would announce that he was considering withdrawing the US from the North Atlantic Treaty Organization for what he sees as its failures to support US military action in Iran.
