About this relationship
Australia and East Timor share a relationship forged in conflict and shaped since by disputes over shared maritime resources, though it has moved toward closer partnership in recent years.
Australia led the international peacekeeping force that intervened in 1999 to restore order after Indonesia's withdrawal and violence surrounding East Timor's independence referendum, a role widely credited with enabling the territory's path to full independence in 2002.
The relationship was later strained by protracted disputes over the maritime boundary and the division of oil and gas revenues in the Timor Sea, worsened by revelations that Australian intelligence had covertly monitored East Timorese cabinet negotiations during boundary talks, a scandal that damaged trust for years.
The two countries resolved their maritime boundary through a 2018 treaty establishing a permanent dividing line and revenue-sharing arrangements for the Greater Sunrise gas field, removing a longstanding irritant, and Australia has since remained one of East Timor's largest aid donors and a supporter of its bid for full ASEAN membership.
Overall, the relationship has evolved from one marked by historical debt and unresolved grievance toward a steadier partnership centered on development assistance, security cooperation, and shared regional interests, even as memories of the espionage dispute and wartime intervention continue to shape mutual perceptions.
The position in the international influence ranking of Australia is 13, while East Timor is situated 69 places below in the ranking (position 82).

East Timor is a small, predominantly Catholic country located in Southeast Asia. It gained independence from Indonesia in 2002, after a long and violent struggle for self-determination. The country is located on the eastern end of the island of Timor, which it shares with the Indonesian province of West Timor.
East Timor has a population of around 1.3 million people and is one of the poorest countries in Asia. It has a tropical climate and a mostly mountainous terrain, with a narrow coastal plain. The economy is based largely on agriculture, with coffee being a major export crop.
Since gaining independence, East Timor has faced significant challenges, including high levels of poverty and unemployment, limited infrastructure and access to basic services, and a lack of natural resources. The country has also faced ongoing political instability, with frequent changes of government and tensions between different political factions.
Despite these challenges, East Timor has made progress in recent years, including improving its education system, strengthening its healthcare system, and increasing access to clean water. The country has also developed closer relations with its neighbors, including Indonesia and Australia, and has become a member of the Association of Southeast Asian Nations (ASEAN).
Geography & terrain
Occupies the eastern half of Timor island and is dominated by a rugged, mountainous central spine (Mount Ramelau is the highest point), with narrow coastal plains. Tropical climate with a pronounced wet and dry season. Coastline on both the Timor Sea and Savu Sea. The steep, forested interior is difficult to traverse and has historically favored small defending or resisting forces over larger conventional ones, even as the coastal lowlands remain easier to approach.
Australia is a sovereign country located in the southern hemisphere, comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. It is the sixth-largest country in the world by land area, and is the world's largest island country. The capital city is Canberra, and the largest city is Sydney.
Australia is a federal parliamentary democracy and a constitutional monarchy, with Queen Elizabeth II as its head of state. It has a strong tradition of democracy and a commitment to human rights. The country has a diverse and thriving economy, with a GDP per capita among the highest in the world. It is a member of the United Nations, the World Trade Organization, and many other international organizations.
Australia has a robust relationship with its regional neighbors and is an active player in regional and international affairs. It has a close alliance with the United States and is a member of the Five Eyes intelligence-sharing network. It also has strong ties with countries in the Asia-Pacific region, particularly Indonesia, Japan, and New Zealand.
Geography & terrain
An island continent, mostly flat and arid — over 70% is desert or semi-arid, with the population concentrated on the temperate coastal fringes, especially the east and southeast. Its isolation and surrounding ocean have meant it has never faced a foreign land invasion. Climate ranges from tropical in the north to temperate in the south.

The relation between East Timor and Australia hasn't changed recently, and it remains at 9.9.
Score history
Let's suppose a hypothetical conflict occurs between both countries:
Initial phase
Australia's larger military budget and stronger air power give it an advantage in the initial stages of the conflict, with the ability to target key military positions and infrastructure.
Force composition
Australia can also call on significantly more personnel, counting both active-duty and reserve forces. Australia's advantage extends to naval power as well.
Ground campaign
East Timor's terrain could make a rapid ground campaign difficult: Occupies the eastern half of Timor island and is dominated by a rugged, mountainous central spine (Mount Ramelau is the highest point), with narrow coastal plains. Dili would likely be a focal point of the campaign: The capital holds the country's only significant port and international airport, making it the sole major point of entry. Australia's terrain could make a rapid ground campaign difficult: Its isolation and surrounding ocean have meant it has never faced a foreign land invasion. Torres Strait would likely be a focal point of the campaign: The narrow sea passage separating the Australian mainland from Papua New Guinea, linking the Coral Sea and the Arafura Sea. Australia's larger population could also support a prolonged resistance.
Prolonged conflict
Australia's stronger economy could help sustain military operations in a prolonged conflict. East Timor also devotes a larger share of its economy to defense (about 2.4% of GDP), a more militarized posture that could be easier to sustain over time. Occupying East Timor outright would likely prove costly given its terrain.
Overall assessment
Overall, the numbers favor Australia, giving it an estimated 85.8% chance of coming out on top. Turning that edge into a decisive win over East Timor — and holding any ground taken — would still be far from guaranteed.
