Australia will build a nuclear-powered submarine fleet in a major new alliance with the US and Britain to counter the worrying rise of China in the Pacific. Prime Minister Scott Morrison on Thursday morning unveiled Australia's role in a landmark tripartite security group, known by the acronym 'AUKUS', to switch to nuclear-powered submarines with help from its two of its biggest allies. Mr Morrison was joined virtually for the announcement by US President Joe Biden and UK Prime Minister Boris Johnson in a historic joint press conference. The deal will mean Australia will walk away from its controversial deal to spend up to $90 billion buying French diesel-powered submarines. This is the first time Australia has ever embraced nuclear power after decades of debate – and the first time the US and UK have shared their nuclear submarine technology with another nation. But he said Australia has no plans to acquire nuclear weapons or build its own nuclear power capabilities. Australia has at least 40 per cent of the world's uranium supplies and the new submarine deal could pave the way for the country to embrace nuclear power to drastically reduce carbon emissions. The move towards a nuclear Australia has been described as 'China's Worst Nightmare' in a strategic bid to counter its influence in the region – especially in the South China Sea. 'Our world is becoming more complex, especially here in our region – the Indo-Pacific. This affects us all. The future of the Indo-Pacific will impact all our futures,' Mr Morrison said.

'So AUUKUS is born – a partnership where our technology, our scientists, our industry, our Defence Forces, are all working together to deliver a safer and more secure region that ultimately benefits all.' Mr Morrison said the submarines would be built in Adelaide in co-operation with the US and the UK. Thursday's announcement came just days before Mr Morrison travels to Washington DC for the first in-person summit of the four 'Quad' nations – Australia, US, Japan and India. Australia's relationship with China has become increasingly hostile ever since Mr Morrison demanded an inquiry into the origins of the Covid pandemic, which originated in the Chinese city of Wuhan in late 2019. Arbitrary bans and trade tariffs were imposed on billions of dollars worth of key Australian exports to China including barley, wine, beef, cotton, seafood, coal, cobber and timber. Australia is now set to follow its allies the US and UK, who both use nuclear technology, with speculation it would tear up the submarine deal with France. Senior Australian ministers were involved in a flurry of late-night meetings on the top-secret shipbuilding program on Wednesday, with Anthony Albanese and other senior Labor MPs briefed on the matter.

Mr Morrison reportedly tried to speak with the French President Emmanuel Macron on Wednesday regarding the new deal. News of Australia's decision was instead reportedly disclosed to Paris by the secretary of the Defence Department, Greg Moriarty, the ABC reported. The Australian Naval Institute has repeatedly criticised the troubled French submarine project while welcoming the use of nuclear technology. 'With regional tensions increasing, then building our own one-off type submarines which will arrive in the early 2030s is not good enough. We have no guarantee they will work,' the article stated. 'When we built the Collins class submarines (at exorbitant expense) they did not work properly for several years. 'Instead we should buy 12 of a proven design which is already in the water. We want long-range hunter-killer vessels. We also want them to be able to stay submerged for long periods to avoid detection. Nuclear does this in spades.' It is speculated the US had planned to operate some of its nuclear submarines from Perth's naval base HMAS Stirling. Pictured: The Sheean in Tasmania in April.

Biden will next week host his first in-person summit of leaders of the Quad nations — made up of Australia, India, Japan and the United States — which have been coordinating against China's growing reach. 'Hosting the leaders of the Quad demonstrates the Biden-Harris administration's priority of engaging in the Indo-Pacific, including through new multilateral configurations to meet the challenges of the 21st century, said Press Secretary Jen Psaki as she announced the September 24 summit in a statement. 2019 : Australian intelligence services conclude that China was responsible for a cyber-attack on Australia's parliament and three largest political parties in the run-up to a May election.

Officials are increasingly concerned at the way China is laying claim to the South China Sea, ignoring other nations territorial claims. Under current international law Vietnam, Malaysia, Brunei, the Philippines, Indonesia, China and Taiwan all claim a portion of the South China Sea. A Congressional report from earlier in July found China 'gaining effective control' of the region in recent years, which is rich in oil and natural gas deposits, by increasing their military presence and building up artificial islands. As a result, the US and allies make frequent 'freedom of navigation' voyages through international waters in the region, drawing angry rebukes from Beijing.
