What You'll Learn
Australia's nuclear history
Australia does not possess nuclear weapons and is not seeking to develop them. The country has, however, been involved in the development and testing of nuclear weapons in the past.
During the 1950s, Australia participated in the development of the Blue Streak missile, a medium-range ballistic missile intended for the delivery of a nuclear warhead. Australia also hosted British nuclear testing in the Monte Bello Islands, Emu Field, and Maralinga between 1952 and 1957. The Maralinga testing site was established in 1955, and the traditional Aboriginal owners of the land, the Maralinga Tjarutja, were forcibly removed. A total of seven major tests were conducted at Maralinga, with a few hundred smaller-scale tests carried out at Emu Field and Maralinga between 1953 and 1963.
In 1958, Australia's first nuclear reactor, the HIFAR reactor, became operational. This was followed by the MOATA reactor in 1961. Both reactors were located at Lucas Heights, New South Wales, and were exclusively used for research and training. During the 1960s, the Royal Australian Air Force continued to investigate obtaining nuclear weapons. However, Australia signed the Nuclear Non-Proliferation Treaty in 1970 and ratified it in 1973.
An anti-nuclear movement developed in Australia in the 1970s, focusing on prohibiting nuclear weapons testing and limiting uranium mining and export. Uranium mining was heavily opposed in Australia during this time due to its connection to nuclear weapons. In 1985, the Australian government passed the Nuclear Non-Proliferation (Safeguards) Act, which established a national system of accounting for and controlling nuclear material in the country.
Australia has since actively contributed to international efforts toward nuclear disarmament and non-proliferation. The country co-chairs the Friends of the CTBT Ministerial process with Japan and leads the annual UN General Assembly CTBT resolution with New Zealand and Mexico. Australia also co-founded the Non-Proliferation and Disarmament Initiative (NPDI) in 2010, a cross-regional group of 12 countries working towards nuclear disarmament and non-proliferation.

Nuclear disarmament efforts
Australia is a non-nuclear-weapon state and does not possess nuclear weapons. It has long championed international nuclear non-proliferation and disarmament efforts through a pragmatic, realistic, and progressive approach. Australia has committed to the goal of a world without nuclear weapons.
Australia has been actively contributing to the International Partnership for Nuclear Disarmament Verification (IPNDV), a US-led informal partnership of over 25 countries working to develop technical solutions for monitoring and verification challenges across the nuclear weapons lifecycle. Australia actively participates in all of IPNDV's working groups, including co-chairing Working Group 5 since 2018.
Australia has also been a key force behind the drafting of the Comprehensive Nuclear-Test-Ban Treaty (CTBT), which bans all nuclear test explosions. The treaty has underpinned the global norm against nuclear testing for over 25 years and has developed a world-class verification system that allows real-time monitoring for possible nuclear explosions worldwide.
Additionally, Australia co-founded the Non-Proliferation and Disarmament Initiative (NPDI) with Japan in 2010. The NPDI is a cross-regional group of 12 countries, including Australia, Canada, Chile, Germany, Japan, Mexico, Nigeria, the Netherlands, the Philippines, Poland, Türkiye, and the United Arab Emirates. The initiative aims to implement the 2010 NPT 64-point Action Plan, which outlines key steps toward disarmament and non-proliferation goals.
Despite Australia's commitment to nuclear disarmament and non-proliferation, it has faced criticism for its actions in certain instances. In 2016, Australia voted against a UN General Assembly resolution that established a mandate for states to negotiate a legally binding instrument to prohibit nuclear weapons. Additionally, Australia has substantial uranium deposits, accounting for 30% of the world's known reserves, which has raised concerns about the potential for nuclear proliferation.

Nuclear non-proliferation treaties
Australia does not possess nuclear weapons and is not seeking to develop them. It is a non-nuclear-weapon state that engages with other countries to advocate for disarmament and non-proliferation.
The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) is an international treaty that aims to prevent the spread of nuclear weapons and weapons technology, foster the peaceful use of nuclear energy, and further the goal of achieving nuclear disarmament and general disarmament. The NPT was negotiated between 1965 and 1968 by the Eighteen Nation Committee on Disarmament, a United Nations-sponsored organisation based in Geneva, Switzerland. The treaty was opened for signature in 1968 and entered into force in 1970.
The NPT contains several provisions aimed at limiting the spread of nuclear weapons technology. Nuclear signatories agreed not to transfer nuclear weapons or technology to any other state, and non-nuclear states agreed not to receive, develop, or acquire nuclear weapons. All signatories agreed to submit to the safeguards established by the International Atomic Energy Agency (IAEA).
The NPT has been extended indefinitely and has more countries as parties than any other arms limitation and disarmament agreement. However, it has been criticised for not being able to stop the proliferation of nuclear weapons, as there are still countries that possess nuclear weapons.
Australia has been actively involved in supporting the NPT and other treaties and initiatives aimed at nuclear disarmament and non-proliferation. Australia co-chairs the Friends of the CTBT Ministerial process with Japan, which bans all nuclear test explosions and limits the technological development of nuclear weapons. Australia also participates in the International Partnership for Nuclear Disarmament Verification (IPNDV) and contributes to the Groups of Governmental Experts (GGE) on nuclear disarmament verification. Additionally, Australia established the Non-Proliferation and Disarmament Initiative (NPDI) in 2010, a cross-regional group of 12 countries working to implement the NPT's Action Plan.

Uranium deposits and mining
Australia holds about 30% of the world's known uranium deposits and is a significant exporter of uranium. However, it does not possess any nuclear weapons and has a very limited nuclear power generation capacity. The country has a long history of uranium exploration and mining, with the first uranium mine opening in the 1950s. Today, uranium mining continues to be a important industry in Australia, providing jobs and economic growth, especially in South Australia and the Northern Territory, where the majority of the country's uranium deposits are located.
Uranium deposits are found in several areas across Australia, with the largest and most significant deposits located in the Australian outback, a vast and sparsely populated region. The majority of uranium mining takes place in South Australia, specifically in the Stuart Highway region, which includes the prominent uranium mining areas of Olympic Dam and Beverley. The Northern Territory, particularly the Tanami Desert region, also hosts significant uranium deposits and has a growing mining industry. Other uranium deposits exist in Queensland and Western Australia, but these have not been extensively mined to the same extent as in South Australia and the Northern Territory.
The Olympic Dam mine in South Australia is one of the world's largest uranium deposits and is a significant contributor to the country's uranium exports. This single site is estimated to contain up to 25% of the world's known recoverable uranium resources. Mining operations at Olympic Dam have been ongoing since the 1980s, and the site also produces significant amounts of copper, gold, and silver. The Beverley Uranium Mine, also in South Australia, is another important source of uranium, employing innovative in-situ leaching methods to extract the uranium ore.
Uranium mining in Australia is heavily regulated by both state and federal governments, with strict environmental and safety standards in place. The industry is also subject to international agreements and inspections to ensure compliance with global standards. Despite this, uranium mining remains a controversial topic in Australia, with opposition from some environmental and indigenous groups. There are concerns about the potential impact on the environment, particularly water sources, and the health and safety of local communities.
To address these concerns, uranium mining companies in Australia are required to adhere to rigorous environmental impact assessment processes and rehabilitation programs. These measures aim to minimize the industry's environmental footprint and ensure that local ecosystems and water sources are protected. Additionally, there are strict controls on the handling, storage, and transportation of uranium ore and associated materials to mitigate health and safety risks for workers and nearby communities.
In conclusion, uranium deposits and mining are significant aspects of Australia's economy and energy sector. With vast reserves, the country plays a crucial role in supplying uranium to the global market. The industry is carefully regulated and monitored to ensure environmental sustainability and community safety. However, ongoing debates and discussions surrounding the social license to operate uranium mines highlight the need for continued dialogue and engagement with local communities and stakeholders.

Nuclear energy and submarines
Nuclear energy has been used to power submarines since the launch of the USS Nautilus in 1954. Nuclear-powered submarines have several advantages over traditional diesel-electric submarines, including increased endurance, speed, and stealth capabilities. Nuclear-powered submarines can stay submerged for months at a time, extending their range and making them a critical military asset.
However, nuclear-powered submarines also have significant drawbacks. One of the most pressing concerns is safety. Nuclear reactors are intricate systems that necessitate meticulous maintenance and monitoring to function safely. A nuclear accident, such as a reactor coolant leak or a control system failure, could result in a catastrophic release of radiation, endangering both the crew and the environment.
The production and disposal of nuclear waste pose additional environmental risks. Nuclear reactors generate radioactive waste that remains hazardous for thousands of years. When nuclear reactors used in submarines and aircraft carriers are decommissioned, the radioactive components are carefully managed and monitored by entities like the Department of Defense and the Department of Energy.
Australia does not possess nuclear weapons and is not seeking to develop them. Australia has ratified various treaties, such as the Nuclear Non-Proliferation Treaty, to prevent nuclear proliferation and promote disarmament. While Australia has substantial uranium deposits, comprising 30% of the world's known reserves, uranium mining faced opposition due to its association with nuclear weapons. Australia's current policy aims to develop the export potential of its uranium industry within strict international agreements to prevent nuclear proliferation.
