Australia will provide full support to Ukraine, which is fighting a war against Russia, even if the US withdraws its own, the prime minister says.
Anthony Albanese and other world leaders have reiterated their support for Ukraine after US President Donald Trump was involved in a heated exchange with Ukrainian President Volodymyr Zelenskiy at the White House over the war and a potential peace deal.
After a heated row, Mr Trump threatened to stop support for Ukraine and accused Mr Zelenskiy of being ungrateful for US aid in its battle against the invading forces.
Mr Albanese said Mr Zelenskiy remained a hero and reiterated his support for Ukraine's defence.
"We have unequivocal and unconditional support for the brave struggle of the people of Ukraine," he reiterated in Sydney on Sunday.
"Ukraine is defending its national sovereignty, but it's also defending the international rule of law.
"That is why Australia has a national interest in providing support - we've already provided $1.5 billion of support, of which $1.3 billion has been military and defence support."
The prime minister said any further financial or military support for Ukraine was being constantly considered.
Mr Zelenskiy had reportedly viewed the meeting with Mr Trump as an opportunity to convince the US not to side with President Vladimir Putin, who ordered the invasion three years ago.
Instead, Mr Trump and Vice President JD Vance lectured Mr Zelenskiy, saying he showed disrespect, driving relations with Kyiv's most important wartime ally to a new low, according to Reuters.
"You're not in a good position. You don't have the cards right now. With us, you start having cards," Mr Trump said.
Opposition home affairs spokesman James Paterson said imposing a ceasefire on Ukraine wouldn't be acceptable and would be a win for the Russian leader.
Despite the tense meeting between the Ukraine and US presidents, Senator Paterson said America was crucial to any ceasefire negotiations.
"It's very hard to see how peace can be durable if there isn't American leadership, if there isn't an American security guarantee," he told ABC's Insiders program on Sunday.
"That does seem to be something that is part of the negotiations between Zelenskiy and Trump, and we're all hopeful that that is able to be achieved."
Senator Paterson also said Australia shouldn't reconsider its defence alliance with the US, despite the Oval Office blow-up.
"Occasionally, even between allies, when there is contention, diplomacy can be very robust," he said.
"(It's) critical to have American leadership in the world.
"That's in the world's interest, and ... that's in as America's interest, and I hope that we are able to achieve a ceasefire on acceptable terms to Ukraine."
Treasurer Jim Chalmers said Australia was unequivocal in its support for Ukraine.
"We couldn't be more supportive of President Zelenskiy and his people," he told Sky News.
"This is a brave and courageous country.
"It has a democratically elected leader who will go down in history for the bravery of his position and his leadership, and we support him and his country without reservation."
Opposition defence spokesman Andrew Hastie said the US President's stance on trade and security had implications for Australia.
"We need to demonstrate a strong hand," he told Sky News.
"President Trump studies your cards very closely, and I think he wants to know that his allies have a strong hand.
"Australia stands with Ukraine.
"We've always stood with Ukraine since Russia's illegal, immoral and unjustified invasion of Ukraine ... we want to see Ukrainian sovereignty upheld in any peace settlement."
