Australia's partnership with Tonga is anchored in shared values, respect, and mutual benefit. The Tongan values of Feveitokai'aki (sharing and cooperating), Falala'anga (trust), and Fefaka'apa'apa'aki (mutual respect) characterise and guide our partnership. Our two countries hold enduring people-to-people links, nurtured through institutional, educational, cultural, church and sporting relationships and growing diaspora connections. In 2025, Australia and Tonga celebrated 55 years of diplomatic relations, but our peoples share a much longer history.

As fellow members of the Pacific Islands Forum, Australia and Tonga recognise that our respective national interests are served by a strong and enduring bilateral partnership and a peaceful, stable and prosperous Pacific. In recent years, at the request of the Tongan Government, Australia responded immediately following the COVID-19 pandemic and the 2022 Hunga Tonga-Hunga Ha'apai volcanic eruption and tsunami, contributing significantly to relief, recovery, and reconstruction efforts.

Our partnership, however, is not limited to times of crises: we have a long history of working together to address shared social, economic and security priorities, including enhanced state resilience, improved human development and climate action. Australia remains Tonga's largest bilateral development partner and a trusted security partner through an extensive defence cooperation program and a long-established policing partnership.

Joint Objectives of the Australia-Tonga Development Partnership

The overarching goal for the Australia-Tonga development partnership is a peaceful, stable and prosperous Tonga.

Our development partnership objectives draw on partner priorities and our long-standing partnerships. They work to support the implementation of the Tonga Strategic Development Framework 2026-2035 (TSDF III) and are in line with the 2050 Strategy for the Blue Pacific Continent.

Objective 1 – Improving national resilience to climate change, disasters, and security challenges

Climate change remains the single greatest threat to the livelihoods, security, and wellbeing of Tongans. Australia will continue working in partnership with the Government of Tonga and communities to enhance national resilience and advance security and sovereignty. Australia will support this priority in line with TSDF III National Outcomes of improving climate resilience and advancing security and sovereignty.

Objective 2 – Strengthening fiscal stability, accountable governance, and economic performance

Tonga's economy is recovering after recent, successive shocks. At high risk of debt distress and facing account deficits, Tonga has identified the need to strengthen public finances and administration, improve the business environment, and invest in improved infrastructure for productivity and growth. Australia will support this priority in line with TSDF III National Outcomes of strengthening inclusive good governance and improving infrastructure.

Objective 3 – Enhancing health, gender equality, and social outcomes for all Tongans

Australia and Tonga are committed to building human capital, so that all Tongans can achieve their potential and drive economic growth. This objective is aligned to TSDF III National Outcomes of balancing urban and rural development and empowering human development with gender equality.

Climate Change

Tonga is rated as one of the most at-risk countries to climate change and natural hazards. Climate modelling predicts more heat waves and drought impacting human health and agricultural productivity; sea level rise exacerbating inundation events; intensified cyclones causing widespread damage; and ocean acidification and warming impacting local fisheries. Strengthening climate-resilient infrastructure and services remains a shared priority, with Australia and Tonga working closely to close critical gaps.

Tonga has a strong commitment to climate action and a strategic climate and disaster policy framework. Despite Tonga's negligible contribution to global greenhouse gas emissions, its second Nationally Determined Contribution (NDC) to the Paris Agreement includes a transition to 70% renewable electricity by 2030 and sets an ambition of 100% by 2035. National commitments are being translated to meaningful action through initiatives such as the Tonga Climate Change Trust Fund, which provides financial support for community-based adaptation and mitigation. However, Tonga faces an estimated USD289m climate financing gap to 2030.

To support Tonga's climate change adaptation and mitigation priorities, Australia will deepen efforts to integrate climate considerations across the development program, capitalising on the strength of our partnerships built over many years. A focus will be on supporting communities to adapt and manage climate risks facing their wellbeing, livelihoods, and assets, including through a new national and locally-led partnership for climate resilient communities, the Tonga Australia Partnership for Resilient Communities. We will also support underlying resilience through support to strengthen social protection systems and through efforts to address gender and social inequalities. We will build targeted strategies for climate induced environmental and naturals hazards into our health system strengthening partnership. We will also continue to support the capacity of the National Disaster Risk Management Office and build humanitarian response capabilities, through our new Tala Kei Kapa humanitarian investment.

Gender Equality, Disability and Social Inclusion

Tonga has made important progress on gender equality and social inclusion, including high education outcomes for girls, legal protections through the Family Protection Act, and growing participation of women in the public service and business. However, structural and social barriers persist. Women remain underrepresented in political leadership, face constraints on land ownership and economic opportunities, and experience high levels of gender-based violence. People with disability face significant stigma, limited access to services, education and employment, and low participation in decision-making, with gaps in implementation of inclusive policies. Lesbian, gay, bisexual, transgender and gender-diverse people also experience discrimination and exclusion. While policy frameworks are strengthening, progress is uneven and constrained by limited resources and coordination challenges.

Australia is a long-term partner supporting Tonga to advance gender equality, disability and social inclusion through a coordinated bilateral GEDSI portfolio and regional investments aligned with shared development priorities. This includes strengthening the capacity of government agencies and civil society organisations to deliver inclusive policies and services, supporting women’s leadership and economic participation, and improving access to survivor-centred responses to family and gender-based violence. Australia provides core funding and technical assistance to key institutions including the Ministry for Internal Affairs, organisations of people with disability, women’s rights groups and LGBTQIA+ organisations. Australia’s support also focuses on raising community awareness, addressing harmful social norms, and ensuring inclusive, accessible services – while strengthening local leadership and resilience to climate and disaster shocks.
