Over the past decade, Australia has been a frontrunner in terms of digital transformation; the country ranked 11^th globally on the 2020 Global Connectivity Index and 2^nd in the Indo-Pacific. Australia’s better-than-expected economic performance in 2021 was largely owed to increased government efforts at promoting the digitalisation of businesses and government services, with significant investment being poured into the ICT sector under the Digital Economy Strategy and the Regional Connectivity Program. Meanwhile, however, self-reported losses from cybercrime amounted to more than $33 billion during the 2020-2021 financial year (E), while roughly a quarter of cyber incidents reported during the same period involved Australia’s critical infrastructure or essential services (E). In the cyber diplomacy realm, Australia has traditionally been a prominent member of the ‘like-minded’ group, promoting a vision of a free, open, and secure cyberspace that is very much in line with EU values and efforts.

Thanks to its regulatory powers, robust digital economy, and active foreign and security policy, the European Union is one of the key players in cyberspace. The EU strongly promotes the position that international law, and in particular the United Nations (UN) Charter, applies in cyberspace. As a complement to binding international law, the EU endorses the voluntary non-binding norms, rules and principles of responsible State behaviour that have been articulated by the UN Group of Governmental Experts. It also encourages the development and implementation of regional confidence building measures, both in the Organisation for Security and Co-operation in Europe and other regions. On a bilateral level, the EU has established cyber dialogues with strategic partners to reinforce the exchange of good practices, lessons learnt and further the idea of responsible state behaviour in cyberspace.

South Korea has made significant progress over the last decades when it comes to connectivity and is currently one of the leading states in terms of access and use of ICTs. While in 1995 less than one percent of Koreans used the internet, four years later the country passed the developed nation average and nowadays South Korea is a global leader in the field of connectivity and internet access. Government support for internet access has been instrumental in fostering this progress in connectivity through governmental programs, trainings and low interest loans to companies providing broadband access. Consequently, cyber issues were recognised as important to the bilateral relationship at the EU-South Korea Summit in 2015, and five cyber dialogues have taken place between 2015 and 2020.

Australia believes that “the foundation for responsible state behaviour in cyberspace is our mutual commitment to existing international law” and that, as per the 2021 report of the Open-Ended Working Group (OEWG), international law is “essential to maintaining peace and stability and promoting an open, secure, […] stable, accessible and peaceful ICT environment.” In particular, Australia has affirmed that the UN Charter applies in its entirety to state actions in cyberspace, including the prohibition on the use of force, the peaceful settlement of disputes, the right to self-defence in response to an armed attack, the law of state responsibility during peacetime, and the doctrine of countermeasures in response to internationally wrongful acts. International legal obligations also include the respect for human rights and fundamental freedoms (especially the right to privacy and freedom of expression), as well as the application of international humanitarian law (IHL) to cyber operations in armed conflict. On the application of IHL, Australia echoes the position taken by the ICRC that “recognition of the application of IHL neither encourages militarisation, nor legitimises resort to conflict in any domain”.

Under the auspices of the UN, the EU and its Member States have consistently reaffirmed that a universal cyber security framework can only be grounded in existing international law, including the Charter of the United Nations in its entirety, international humanitarian law, and international human rights law. 
Addressing issues as to how existing international law and international humanitarian law, including the principles of humanity, necessity, proportionality and distinction, apply to the use ICTs by States is necessary to increase accountability and transparency. International humanitarian law is fully applicable in cyberspace and this should not be misunderstood as legitimising the use of force between states in the cyber domain. The EU has typically opposed calls for the need to adapt existing international law as a means to develop a new legal instrument for cyber issues.

As a member of the 2015 Group of Governmental Experts (UNGGE) and as per the Seoul Framework for and Commitment to an Open and Secure Cyberspace, the ROK recognises that international law, and in particular the UN Charter, is applicable in cyberspace and essential for maintaining security and stability as well as promoting an open, secure, peaceful, and accessible ICT environment. 
The country also acknowledges that cybersecurity must go hand-in-hand with respect for human rights and fundamental freedoms as set forth in the Universal Declaration of Human Rights and other international instruments. The ROK notably co-sponsored the Human Rights Council Resolutions 20/8 and 26/13 concerning the promotion, protection and enjoyment of human rights on the Internet. 
The country supports the idea of increasing interstate engagement and exchanging national views on how international law applies in cyberspace, both at the multilateral level as well as at the bilateral and regional levels.

Australia has been actively involved in both norm-building processes that have been occurring under the auspices of the UN, namely the UN Open-Ended Working Group (GGE) and the OEWG. The country’s 2021 International Cyber and Critical Tech Engagement Strategy notes that the 11 voluntary, non-binding norms on responsible state behaviour agreed under the 2015 UN GGE consensus reports serve to “promote predictability, stability, and security” in cyberspace and should be seen as the “point of departure” for any constructive norm-building discussion. Australian diplomats have consistently reiterated the complementarity between international law and norms of responsible state behaviour, stating that “norms are not a panacea” and that they should not be understood as a standalone “normative framework”, since they do not replace existing state obligations under international law. For this reason, Australia stands against the establishment of binding norms or agreements. The country is not prima facie opposed to discussing other states’ proposals for the development of new norms, but Australia’s own “proactive priority” is reaching agreement of guidance on the implementation of the existing norms. In the current environment, Australia believes that “we will have the biggest impact on international peace and stability if we translate norms ‘on paper’ into norms ‘in practice’”. While not discounting the value of “norms agreed among friends”, it has also highlighted that the framework will only be effective when it is any proposals for new norms would first need to be negotiated, agreed upon, and endorsed by universal consensus.

Since 2014, the EU’s ambition has been to act as an ‘honest broker’ on multilateral discussions surrounding issues of cyber governance and norms of responsible state behaviour, aiming to ensure the support and partnership of proactive players in the context of the global debate. The EU has long promoted the need for voluntary, non-binding norms. It believes that norms crystallised under the UN GGE process should generally not be revisited and that progress should be made on matters relating to their implementation. 
Within the OEWG, the EU advanced a suggestion to develop a global repository of existing practice within the United Nations, which would enable UN member states to showcase how they are implementing the voluntary norms of responsible state behaviour, confidence building and other measures.

The ROK stands in favour of the adoption and elaboration of voluntary, non-binding norms of state behaviour during peacetime. It strongly upholds the 11 non-binding norms agreed upon in the 2015 UNGGE report and believes that further efforts should be undertaken to clarify and concretise them. 
In addition, the ROK has put great emphasis on the principle of due diligence, consistently demonstrating its commitment through public statements at regional and international forums. The country believes that no new legally binding instrument is necessary for the moment, retaining a preference for the ‘soft law’ approach and maintaining that less resilient states should first focus on building capacity rather than reforming regulatory frameworks.

In recent years, Australia has emerged as a regional leader in conversations surrounding cyber resilience in the Indo-Pacific as well as globally. The new 2021 International Cyber and Critical Tech Strategy constitutes one of the most comprehensive documents of its kind, with “secure, resilient, and trusted technology” representing a crucial objective. Key initiatives include enhanced protections for critical infrastructure
and systems of national significance, as well as greater support for businesses
and individuals to develop their cybersecurity resilience. In the past three years, Australian cyber diplomats have brokered a series of bilateral partnerships in the form of cyber Memoranda of Understanding (MOUs); currently there are agreements with India (2020), Indonesia (2018), Papua New Guinea (2018), Singapore (2020), and Thailand (2019), all of which include capacity-building and information-sharing elements. On a regional level, the country is chairing the Asia-Pacific CERT community and the Asia-Pacific cybersecurity operations network. Australians have also significantly extended their regional outreach through their flagship capacity-building initiative, the Cyber and Critical Technology Cooperation Program. Meanwhile, Australia participates in several multipartite initiatives with a strong cyber component such as the Structured Quadrilateral Security Dialogue (the eponymous Quad) along with India, Japan, and the US, and the tripartite AUKUS coalition along with the US and the UK. In international fora, Australia has been a vocal champion of increased international collaboration in cyber capacity building (CCB), welcoming references to further cooperation within the 2021 OEWG report but cautioning against limiting such cooperation to the protection of national, translational and supranational infrastructure. Australia has also argued that CCB should be mainstreamed into the larger development agenda of the UN, specifically the Sustainable Development Goals.

The EU places great importance on cyber resilience and capacity building. Internally, the Union has built a robust legal acquis in relation to the resilience of critical infrastructures, the cornerstone of which rests upon the 2016 Network and Information Security (NIS) Directive and the 2013 and 2019 Cybersecurity Acts. This legal meshwork seeks to integrate cybersecurity into all elements of the supply chain and introduce soft law mechanisms like the EU cybersecurity certification scheme. In doing so, it harmonises national cybersecurity capabilities, cross-border collaboration and the supervision of critical sectors across the EU. 
In the coming months, the Commission intends to add upon the existing cyber-acquis by introducing an array of new initiatives, such as the updated NIS Directive (the so-called NIS2), a proposal on a Critical Entities Resilience (CER) Directive, and a plan to launch a network of Security Operations Centres across the Union. The aim is to create a Union-wide ‘cybersecurity shield’ that will facilitate the detection of cyberattacks and provide an impetus for proactive action. 
This internal buildup of capabilities is supplemented by the development of a specialised ‘cyber diplomacy toolbox’ that allows the Union and its Member States to address cyber incidents through various joint policies, from cooperation and stabilisation measures to restrictive measures and attribution.

Driven by a proliferation of cyberthreats originating in the DPRK, Korean diplomats have consistently maintained that bridging the global gap in cybersecurity capabilities constitutes a central task for states; as such, countries should develop cyber defence capabilities to foster resilience in the global cyber ecosystem. 
The South Korean government has introduced several international cooperation mechanisms, especially through the Korean Internet & Security Agency (KISA) and its Global Cybersecurity Centre for Development (GCCD) project. Through the GCCD, South Korea has worked with the World Bank and a series of partner countries in Latin America to organise workshops and exercises. Another important initiative is the Cybersecurity Alliance for Mutual Progress (CAMP) network, a mechanism launched in 2016 that provides a platform for Korea to share its expertise with a large group of partner countries and help them exchange knowledge and best practices.

The 2021 International Cyber and Critical Tech Engagement Strategy recognises that Australia, and the Indo-Pacific region more widely, faces a “worsening” cybercrime landscape characterized by “expanding threats, low barriers to entry, and increasingly resourceful actors”. Australia acceded to the Council of Europe’s Budapest Convention in 2013 and has since been vocal about the Convention’s status as the “most comprehensive and effective basis upon which to pursue a common international approach”. The country voted against the Russia-sponsored UN resolution on the establishment of a new cybercrime treaty; however, upon the passage of the resolution and the subsequent creation of a dedicated Ad Hoc Committee, Australia has been active in advocating for a “transparent, inclusive, and consensus-based process with multi-stakeholder participation”. More specifically, it has stated that the new Convention should “draw heavily” from existing international instruments such as the UN Convention against Transnational Organized Crime (UNTOC), the UN Convention against Corruption (UNCAC), and especially the Budapest Convention, so as to avoid undermining these regimes and ensure the protection of human rights. Australia has additionally placed great emphasis on the need for international cooperation, with the 2021 Strategy noting that “information sharing, discussion and capacity building are vital to any meaningful response to the threat posed by cybercrime”. The country has launched numerous regional cooperation and capacity-building initiatives, partnering with Pacific Island countries (Tonga, Fiji, Samoa, Vanuatu, Solomon Islands, Niue, Tuvalu) to advance cybercrime law reform and ensure alignment with Budapest provisions.

The EU has been an early champion of the Budapest Convention signed under the auspices of the Council of Europe, given the overlapping membership of the two organisations. Much of the EU’s cyber diplomatic efforts have focused on promoting the Convention as the main instrument of choice for fighting cybercrime on a global level. EU member states have consistently opposed Russian bids for replacing this regime with another legal framework. 
The Union is represented in the recently constituted Ad Hoc Committee established by UNGA resolution 74/247 by its Member States and is currently focused on ensuring that the process is inclusive, transparent, consistent with the progress of the UNGGE and OEWG processes, and committed to legal consistency.

The ROK is generally a strong advocate of strengthening global cooperation against cybercrime. While it is not formally a signatory to the Budapest Convention, the country voted against the Russian-sponsored UNGA resolution calling for a new binding cybercrime treaty. 
To promote cooperation among law enforcement agencies, the ROK’s Supreme Prosecutor’s Office (SPO) convenes regular meetings with the FBI, while also engaging with the Federal Criminal Police Office (BKA) in Germany and the European Cybercrime Centre (EC3) in the Netherlands. 
On the basis of an increased awareness that Internet Service Providers (ISPs) are becoming “important partners to secure electronic evidences”, the SPO works along with Microsoft to operate the Government Security Program (GSP).
