“As we look to the future,we will continue to stand together to defend the principles we share,” Biden said.

He said the US and Australia would work together “to support a free and open Indo-Pacific” and “to promote inclusive economic prosperity in our own nations and across the region”.

“Prime Minister Morrison and the people of Australia:thank you for your partnership and your friendship,” Mr Biden said.

In a speech to the Australian Parliament,Mr Morrison said ANZUS was the “foundation stone of Australia’s national security and a key pillar for peace and stability in our Indo-Pacific region”.

“For seven decades,it has underpinned vital military,national security and intelligence co-operation between Australia and the United States. And much more besides,” he said. “It has been,and I hope always will be,a shared national endeavour;one that has evolved to meet new challenges based on enduring values.”

In his speech to Parliament,Mr Albanese said the anniversary of the ANZUS was a “significant opportunity to not just commemorate our shared history,but look forward to how our relationship will impact our respective futures”.

After six defence ministers in eight years,Mr Albanese and Labor’s defence spokesman Brendan O’Connor accused the government of “neglecting planning on posture,despite deteriorating strategic circumstances”. Defence strategists last year warned the government it no longer had a decade to build up its defences against potential threats,amid aregional arms race fuelled by China’s growing assertiveness throughout the Indo-Pacific.

“A Labor Defence Force Posture Review would ensure the Australian government is considering both long-term strategic posture and whether Australian Defence units,assets,and facilities are prepared for the military to take action in a timely way,” Mr Albanese and Mr O’Connor said.

“The 2020 Strategic Update warned of the rapidly changing circumstances in our region,and stressed that a 10-year strategic warning time for a major conventional attack against Australia is no longer an appropriate basis for defence planning.

“Reduced warning times mean defence plans can no longer assume Australia will have time to gradually adjust military capability and preparedness in response to emerging challenges. Despite this,the Coalition government has never conducted a fully-fledged Force Posture Review.”

Michael Shoebridge,director of the defence program at the Australian Strategic Policy Institute,welcomed the proposal for a new posture review but said it shouldn’t come up at the expense of the obvious moves that need to be made in the short term. This includes boosting Australia’s military presence in the north and the west of the country and helping to upgrade bases in the South Pacific such as Papua New Guinea’s main naval base on Manus Island.

“We already know ADF needs to have more offensive power and to have that need to be more present in places that that matters,” Mr Shoebridge said. “The one thing I want to see from the opposition – they really need to have some initiatives they would do early and not just a set of reviews.”
