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.

Costa Rica has established itself as a leading country in technological adoption, in combination with a complete commitment to sustainability and the protection of the environment. Information and communications technology services accounted for 49% of the country’s exports (twice the average of OECD countries), placing the Central American country at the forefront of the digital economy.

Nigeria is Africa’s most populous country with a population of 211 million people. Nigeria also has the continent’s largest economy, with a total GDP of $440 billion. Nigeria only emerged as Africa’s largest economy in 2014, overtaking South Africa after a GDP rebasing exercise which accounted for the contribution of emerging sectors of the economy, such as the Information and Communication Technology (ICT) sector. Nigeria’s economy had hitherto been petroleum dominated. In Q4 2021, the ICT sector of the economy contributed 15% to GDP, compared to 5% for the oil and gas sector. The percentage of people who use the Internet in Nigeria is 28%, largely through mobile networks. 91% of the population is covered by a mobile network (i.e. 74% by at least a 3G network and 41% by at least a 4G network). Huawei and ZTE have been responsible for constructing major parts of Nigeria’s broadband network (4G, LTE and 5G). Mobile phone subscription coverage is 99% of the population. Active mobile broadband subscription is 42% of the population, while fixed broadband connection is negligible, under 1%. Nigeria has 6 international submarine cables bringing at least 40TB capacity to its shores. There are 7 Internet Exchange Points (IXPs) in Nigeria with 71 peering networks. NigComSat-1, a communications satellite, made possible by cooperation between Nigeria and China, was launched in May 2007. Nigeria has plans to purchase 2 more communications satellites by 2025. Nigeria banned cryptocurrencies in 2021, but floated perhaps Africa’s largest digital currency the e-naira the same year. Despite the cryptocurrency ban, it is still in use in the country although hosted in foreign accounts.
The European Union is a significant partner in Nigeria’s cyberspace. For example, through its EU-Nigeria Digital Economy Package (Global Gateway Initiative), the EU plans a 820 million Euros investment to support Nigeria’s digitalisation strategy through digital infrastructure investments, digitalisation of public services, digital entrepreneurship, digital skills, and digital governance. However, the EU faces strong competition from China, whose investment in Nigeria’s telecommunications sectors is estimated to be $US 16 billion. China also helped manufacture and launch Nigeria’s Communications Satellite and has an equity stake in the parent satellite communications company. Huawei has been an important partner of the Nigerian government in building smart cities and e-government applications in an effort to improve government public services. Nigeria’s cyberspace is governed by several agencies including the Nigerian Communications Commission (NCC) and the National Information Technology Development Agency (NITDA).

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”.

Costa Rica has played a paramount role in the Organisation of American States as is one of seven American countries that sponsored a resolution within the framework of the OAS as part of a Working Group on Cooperation and Confidence-Building Measures in Cyberspace. The resolution is inspired by the work of the United Nations Group of Governmental Experts and aims at enhancing interstate cooperation, transparency, predictability, and stability in cyberspace.

Nigeria’s stance on international law in cyberspace is primarily shaped by its traditional concern over the growing proliferation of global cybercrime. Nigerian diplomats have emphasised the need for a proper legal framework that reflects the ideals and current trends within the African region. Nigeria has neither signed nor ratified the African Union (UN) Convention on Cybersecurity and Personal Data Protection. Less has been said, however, about the application of international law in cyberspace more generally. However, On 6 July 2022, Nigeria acceded to the Council of Europe Convention on cybercrime. The Convention entered into force in Nigeria on 1 November 2022.

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.

Costa Rica has a long history of collaborating on cyber issues within the OAS Cyber Security Program, from training to capacity-building for both the public and private sectors. At a 2019 intervention, Costa Rica recognised the leadership carried out by the aforementioned Working Group in coordinating the response to cyber incidents regionally and establishing a cooperative framework of action to cyber threats.
Costa Rican participation in the UN OEWG is guaranteed until 2025. As part of the second substantive session in 2022, Costa Rica confirmed - along with several other countries - that international law is fully applicable to the use of ICT by states [OH1], with a focus on how international humanitarian law and the principles of humanity, necessity, proportionality, and distinction apply in cyberspace.
An interesting approach was taken by Costa Rica during this session, as the Caribbean country emphasised a multi-stakeholder approach to cybersecurity, involving the private sector, civil society, and researchers’ analysis, information, and capacity on threat.

Nigeria has been an active participant in the OEWG, contributing to the 2021 consensus report. Nigeria’s position acknowledges the applicability of existing international laws in cyberspace and supports the call for the operationalisation of the 11 Norms of responsible behaviour in cyberspace to address its current challenges. Nigeria also upheld the conclusions of the final report of the GGE: that the precedence set by the 2021 OEWG should be a baseline for international cooperation because of the inclusive nature of stakeholder participation.

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.

In 2016, Costa Rican Cybersecurity Incident Response Team (CSIRT) joined CAMP, an international alliance that serves as a platform for the members to enhance their cybersecurity capacity.
Costa Rica is also collaborating with Israel on cyber issues and digital transformation in an effort that has the potential to streamline innovation in the public sector, transforming public services and institutions and positioning Costa Rica as a regional benchmark in cybersecurity.
On a national scale, Costa Rica launched a digital transformation strategy for the public sector in 2018 and is now working to create a strategy for the implementation of Artificial Intelligence. The initiative seeks to promote the use of digital technologies and access to scientific knowledge, innovation, technology, and telecommunications for social and productive transformation.
Having suffered a cyber attack in 2022, Costa Rica is now positioning cybersecurity as a top national priority, and the Ministry of Science, Innovation, Technology and Telecommunications is beginning to implement various actions to detect, respond and correct cyber intrusions, build faster and more robust response protocols, and train individuals in skilled threat detection.

In the International Telecommunication Union (ITU) Cybersecurity Index 2020 which measures commitment to cybersecurity amongst its members , Nigeria ranked 47^th in the world, and 4^th within the African region. In 2021, Nigeria published the updated National Cybersecurity Policy and Strategy, which lays out detailed cybersecurity obligations for different private sector and public sector actors in critical national information infrastructure (CNII) protection and resilience within a context of multiple stakeholders. The National Cybersecurity Policy and Strategy, together with the Cybercrime Act, are the major policy instruments governing cybersecurity in the country.
The Global Cyber Security Capacity Centre (GCSCC) at Oxford University, in 2018, reviewed the maturity of cybersecurity capacity in Nigeria at the behest of the Office of the National Security Adviser (ONSA), using the Cybersecurity Maturity Model (CMM). Nigeria’s CMM report indicated a maturity stage of either start-up or formative stage (maturity stages 1 and 2 out of 5 stages) for the majority of factors, suggesting opportunities for investment. The United Kingdom has pledged some of this necessary investment, with Nigeria set to benefit from a £22 million investment package which aims to support resilience in Africa and the Indo-Pacific region.

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.

Costa Rica is one of the few Latin American countries to have signed the Budapest Convention on Cybercrime, along with the First and Second Protocol (this one was signed in 2022 but yet to be ratified), and is at the forefront of cybercrime legislation in the region.
National legislation on cybercrime is fully compliant with the Convention and is contained in the Law on Intervention of Telecommunications and the Law of Computer Crimes and Related Crimes. It includes penalties for committing cybercrimes in the country. Additionally, legislative regulations were introduced to govern the use of social networks and other electronic means.
Their Cybersecurity Policy from 2017 was updated in 2021 with the creation of the CSIRT, the implementation of cybersecurity protocols across public institutions and the establishment of partnerships with strategic actors, mainly in the private sector.

The Nigerian 2020-2030 National Digital Strategy, which is in line with the African Union Digital Transformation Strategy 2020-2030, emphasises the significance of adopting ‘collaborating approaches’ to fighting cybercrime; it specifically notes that ‘cybersecurity is not a local issue and it requires collaboration with relevant institutions around the globe’. In 2019, the country voted in favour of UNGA resolution 74/247, which established an Ad Hoc Committee to draw up an international convention on cybercrime. The Nigerian position paper prior to the launch of the first substantive session noted the ‘urgent need to define and sanction criminal conduct in cyberspace, improve synergy in trans-national policing capabilities, improve procedural tools and reform/enhance international cooperation, whilst respecting human rights’. In its capacity as a member of ECOWAS, Nigeria has participated in several socialisation-based capacity-building initiatives, including the OCWAR-C project, the GLACY+ workshops and the African Forum on Cybercrime (organised by the African Union).
