Anthony Albanese has continued discussions with US President Donald Trump on topics of trade and security, although a date for their face-to-face meeting remains unconfirmed.

The prime minister revealed the leaders spoke in a social media post just before midnight on Thursday.

It was the fourth phone phone call between the pair, which Albanese said was ‘warm and constructive’.

‘We discussed our trade and economic relationship as well as areas for growth including critical minerals.

‘We also discussed shared US-Australia security interests.’

A readout of the meeting said Albanese discussed economic cooperation, as well as trade and critical minerals important to both countries.

‘Leaders also discussed the strength of our relationship and the importance of our shared security interests,’ it said.

There has been no announcement on when the leaders will conduct their first in-person meeting, something Australia has sought since Trump’s rise to the presidency in November.

Initially, the two planned to meet in June during the G7 summit in Canada. However, the meeting was called off as Trump returned to the US early to manage issues in the Middle East.

The conversation occurred just weeks before a United Nations general assembly meeting, which Trump will also attend. Australia is anticipated to join the UK, France, Canada, and others in advocating for the acknowledgment of a Palestinian state.

Australian ambassador to the US Kevin Rudd welcomed the phone call between the two leaders.

‘Lots going on in the US-Australia relationship. And going from strength to strength,’ he said on social media.

The phone call coincides with efforts by Australia to get the US to drop tariffs on exports.

Trump imposed a baseline tariff of 10 per cent on all Australian goods to the US and a 50 per cent tariff on steel and aluminium.

Concurrently, the US is assessing the AUKUS trilateral security pact, which involves Australia potentially investing $386 billion in nuclear-powered attack submarines, to ensure its compatibility with Trump’s ‘America first’ policy.

The US has been pushing Australia to raise its defence spending to 3.5 per cent of gross domestic product.

The government is currently spending 2.02 per cent with a view to increasing that sum to 2.33 per cent of GDP by 2033/34.

Employment Minister Amanda Rishworth said the phone call between the two leaders to expanded on ties between the allies.

‘We have the lowest trade tariffs worldwide with the US, which no doubt strengthens what is already a cordial relationship between the two leaders,’ she mentioned on Seven’s Sunrise program on Friday.

‘As the prime minister has indicated, they’ll meet when it’s convenient for both parties.

‘Clearly, there’s a connection there with four phone calls.’

But Liberal senator Jane Hume said more work was needed to be done to secure a face-to-face meeting with the US president.

‘It’s been 300 days now since President Trump has was elected, and still no meeting between our leaders, and that’s a concern,’ she told Seven.

‘We want Anthony Albanese to step up and represent Team Australia with President Trump, and particularly to secure our AUKUS agreements.’
