What You'll Learn

Nuclear weapons testing
In 1984, the Nuclear Disarmament Party won a Senate seat, reflecting the growing strength of the anti-nuclear movement. However, the movement suffered a setback when the newly elected Labor Government failed to stop uranium mining. Despite this, by the late 1980s, the anti-nuclear movement appeared to have prevailed, as the price of uranium fell, the costs of nuclear power rose, and CANE was disbanded.
Australia has no nuclear weapons or nuclear-powered vessels as of 2021. The country has been an active participant in international efforts to promote nuclear disarmament and non-proliferation. It has been a key force behind the drafting of the Comprehensive Nuclear-Test-Ban Treaty and is a committed party to the South Pacific Nuclear Free Zone Treaty (Treaty of Rarotonga). Australia has also indicated its support for the Treaty on the Southeast Asia Nuclear Weapon-Free Zone (Bangkok Treaty), although it is not a signatory.
In recent years, there has been a renewed focus on nuclear issues in Australia, with the International Campaign to Abolish Nuclear Weapons (ICAN) founded in the country in 2007. ICAN's efforts were recognised with the Nobel Peace Prize in 2017. In 2023, Australia's foreign minister, Penny Wong, affirmed the country's commitment to nuclear disarmament and engagement with the Treaty on the Prohibition of Nuclear Weapons (TPNW). However, Australia has not yet signed or ratified the TPNW, citing the need for effective verification and enforcement mechanisms.
Public opinion in Australia remains largely opposed to nuclear power, with concerns about the environmental and health impacts of uranium mining and nuclear energy. Surveys indicate that the majority of Australians support the development of renewable energy sources over nuclear power, and there is widespread support for maintaining Australia's ban on nuclear power plants.

Uranium mining and export
Uranium mining in Australia has been a highly debated topic since the 1970s, with opposition groups citing environmental impacts, indigenous land access, and nuclear proliferation as reasons for restricting or ceasing the industry. The Australian anti-nuclear movement gained momentum in 1972–1973 due to French nuclear testing in the Pacific, and again in 1976–1977 with debates around uranium mining in Australia. Groups like the Movement Against Uranium Mining and Campaign Against Nuclear Energy (CANE) were established, cooperating with other environmental organisations.
Uranium mining in Australia began in 1954, and the country has the world's largest known uranium resources, with almost one-third of the world's total. In 2019, Australia exported 6,613 tonnes of uranium, which was 12% of world production, and in 2022, it produced 4,820 tonnes of U3O8 (4,087 tU), making it the fourth-largest producer globally. Uranium mining has been a significant part of Australia's economy, with the mining sector contributing 10.4% to the national GDP between 2019 and 2020.
Uranium mining activities have faced limitations due to federal and state government policies, with the Labor Party's stance on uranium mining varying over time. In 1982, the Labor Party introduced a "Three Mine Policy," restricting mining to three sites: Ranger, Nabarlek, and Olympic Dam. However, with the depletion of reserves at Nabarlek, the Beverley Uranium Mine became the third site. As of 2021, only two mines are operational: Olympic Dam and Four Mile. Uranium mining in Australia is solely for electrical power generation or nuclear research, and almost all of it is exported under strict International Atomic Energy Agency safeguards.
The anti-nuclear movement in Australia has had a significant impact, with rallies in the 1980s attracting hundreds of thousands of participants. Public opinion surveys revealed that about half of Australians opposed uranium mining and export. The movement's efforts led to the creation of the Kakadu National Park in the 1980s, surrounding the Ranger uranium mine. The Sydney city council proclaimed Sydney nuclear-free during this period, and the anti-nuclear movement's success seemed assured by the late 1980s with the decline in uranium prices and the rise in nuclear power costs.

Nuclear power stations
In 1952, South Australian Premier Tom Playford announced plans for a nuclear power station on the shores of Spencer Gulf, specifically in Backy Bay (later renamed Fitzgerald Bay) between Whyalla and Port Augusta. However, the station was never built. In 1969, a 500 MW nuclear power station was proposed for the Jervis Bay Territory, but this plan was also abandoned due to local opposition and economic concerns.
In the late 1970s, the Western Australian Government under Charles Court announced plans for a nuclear power reactor near Perth, despite public protests. In 1979, a site for the reactor was selected at Wilbinga, 70 kilometres north of Perth. Court predicted that at least 20 more nuclear power stations would be needed by the end of the century, but these plans did not come to fruition.
In 2007, there was renewed interest in building a nuclear power station in the Upper Spencer Gulf region of South Australia, with businessman Ron Walker considering Portland as a possible location. However, this idea faced community opposition and no formal proposal was ever made.
In 2012, a study compared a combination of solar and wind technology with a reference nuclear reactor as a replacement for an ageing coal power station. The nuclear energy option was found to be favourable in terms of cost, reliability, and greenhouse gas abatement. However, the high costs and long construction times associated with nuclear reactors remain significant barriers.
Federal Opposition Leader Peter Dutton and the Liberal-National Coalition have stated their intention to build nuclear reactors in communities across Australia if they win the next federal election. However, critics argue that nuclear energy is not a viable solution for Australia due to concerns about water usage, climate pollution, and the availability of cleaner and more cost-effective renewable energy alternatives.

Nuclear disarmament
The anti-nuclear movement in Australia has a long history, dating back to the 1970s with debates over French nuclear testing in the Pacific and uranium mining in Australia. In 1975, Moss Cass, Minister for the Environment and Conservation, expressed concerns about the effects of uranium mining, particularly on the northern Aboriginal people. The anti-nuclear movement gained momentum in the 1980s, with rallies drawing hundreds of thousands of participants. The movement focused on stopping uranium mining and exports, abolishing nuclear weapons, and creating a nuclear-free Pacific.
Australia has consistently promoted nuclear disarmament and non-proliferation efforts through its support for the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Australia is also a party to the South Pacific Nuclear-Free Zone Treaty (Treaty of Rarotonga) and the Treaty on the Southeast Asia Nuclear Weapon-Free Zone (Bangkok Treaty). Australia has no nuclear weapons or nuclear-powered vessels, and the government has stated its commitment to the goal of a world without nuclear weapons.
In 2023, Foreign Minister Penny Wong affirmed Australia's support for nuclear disarmament, stating that the country is engaging constructively to identify realistic pathways for nuclear disarmament. However, Australia has not yet signed or ratified the Treaty on the Prohibition of Nuclear Weapons (TPNW). The International Campaign to Abolish Nuclear Weapons (ICAN), founded in Australia in 2007, aims to prohibit and eliminate nuclear weapons through a new international treaty.

Nuclear-powered vessels
The anti-nuclear movement in Australia has a long history, dating back to the 1970s with debates over French nuclear testing in the Pacific and uranium mining in Australia. The movement has focused on issues such as halting uranium mining and exports, abolishing nuclear weapons, and creating a nuclear-free Pacific. There has been significant public opposition to the visits of U.S. nuclear warships to Australia.
Australia has no nuclear power stations and only a few operating uranium mines as of 2021. Uranium mined in Australia is primarily for export. The Australian government has supported the creation of nuclear-weapon-free zones and has committed to the goal of a world without nuclear weapons.
There has been some discussion of nuclear energy in Australia's energy future, with the Coalition government proposing a nuclear energy plan. However, this has been met with opposition from voters, who have chosen renewable energy sources such as batteries over nuclear power in recent elections. Concerns about the high costs, safety, and environmental impact of nuclear energy have been raised by the public and experts.
Overall, Australia's lack of nuclear-powered vessels is part of a broader context of the country's anti-nuclear movement and ongoing debates about the role of nuclear energy in its energy landscape.
