Australia is unique in that it is the only country that is also a continent. As an island, it has no land borders with other nations. However, it does share maritime borders with several nations. Australia has established maritime borders with Indonesia, Papua New Guinea, New Zealand, the Solomon Islands, New Caledonia, and Timor-Leste. These borders are significant due to the presence of valuable resources in these regions, and disputes over these resources have occurred.

What You'll Learn
Australia has no land borders with other nations
Australia is an island and the world's only country that is also a continent. As such, it has no land borders with other nations. However, it does share maritime borders with several countries.
Australia's closest neighbour is New Zealand, and the two countries officially established their maritime border in 2006, adhering to boundaries that had been in place since the 1980s. Australia also shares maritime borders with Papua New Guinea, Solomon Islands, New Caledonia, and Vanuatu.
In addition, Australia has a unique geographical position, which has resulted in disputes over maritime borders with some nations. Australia and Indonesia have had a contentious relationship regarding their shared maritime border, which is defined by four treaties, one of which is yet to be ratified. The primary dispute between the two countries was over control of the area, with Indonesia concerned about potential denial of access to oil reserves.
Australia and Timor-Leste also had disagreements regarding their maritime border, with a treaty finally being signed in 2018 to establish a permanent border. The dispute centred around how the two countries would share oil and gas resources in the border region.

Indonesia shares a maritime border with Australia
Australia is surrounded by oceans and does not share a land border with any country. However, it does share maritime borders with several countries, including Indonesia.
The maritime boundary between Australia and Indonesia is divided into three segments. The first segment runs from the Australia-Indonesia-Papua New Guinea tripoint in the western entrance to the Torres Straits to the point where the territorial waters of the two countries meet the eastern limits of Timor-Leste's territorial waters claims. The second segment runs westward from this point to a location in the Indian Ocean. The third segment is between Christmas Island and Java in the Indian Ocean.
The eastern segment of the boundary was established by the 1971 and 1972 treaties, with the former delimiting the border from A3 to A12 and the latter extending it from A12 to A16 on the eastern border of the Australia-Timor-Leste joint petroleum development area. The 1972 treaty also brought the boundary to Point A25, northeast of Australia's Ashmore Island.
The Australia-Indonesia maritime boundary is unique in that it divides overlapping maritime claims into two sets of boundaries: the northern seabed boundary (continental shelf) and the southern fisheries boundary (exclusive economic zone). This creates an area of overlapping sovereign rights, which are provided for in Article 7 of the 1997 Agreement.

Papua New Guinea shares a maritime border with Australia
Australia is the only country that is also a continent. It is the sixth-largest country in the world and is surrounded completely by water. While no country borders Australia in the traditional sense, it does share maritime borders with some nations.
In 1978, Australia and Papua New Guinea signed a treaty that defined their maritime border. The agreement has been praised for how it addressed boundary challenges that affected the lives of the native people. The maritime border between the two countries is situated in the Coral Sea.
Papua New Guinea's only land border is with Indonesia, as they share the island of New Guinea. The land border between Papua New Guinea and Indonesia was determined in 1974. The country also shares maritime borders with Australia and Indonesia. The borders of Papua New Guinea began taking their present-day shape in the 19th century when the country was under the control of the Germans and the British.

New Caledonia shares a maritime border with Australia
No country borders Australia in the traditional sense due to its unique geographical position. However, several nations share maritime borders with Australia. One such nation is New Caledonia, which shares a maritime border with Australia in the Coral Sea. This border was established by the Australia–France Marine Delimitation Agreement, a treaty signed in 1982 and ratified in 1983. The treaty sets out two separate maritime boundaries, one of which is between Australia and New Caledonia. This boundary consists of 21 straight-line segments defined by 22 individual coordinate points, forming a modified equidistant line between the two territories.
New Caledonia is a French-controlled territory located in the Pacific Ocean, to the northeast of Australia. It was named by James Cook, the first European to see the area, as it reminded him of Scotland. New Caledonia has a unique status under French law, where same-sex marriage is legal, and French law recognises dual citizenship. Outside of the capital city of Noumea, however, attitudes may be more conservative, and it is important to respect local dress and behaviour standards.
The maritime border between Australia and New Caledonia is significant due to the vast quantity of resources located in the region. Maritime borders have been a source of conflict between nations over the years, as they negotiate how to share these valuable resources. In the case of Australia and New Caledonia, the treaty establishing their maritime border has been praised for addressing boundary challenges that affected the lives of the native people.
Australia's maritime jurisdiction is carefully maintained and monitored by Geoscience Australia, which provides data and maps illustrating the country's maritime limits and zones. These maps are produced in consultation with relevant government departments and reflect the changing nature of Australia's coastline. Australia's proximity to its neighbouring countries also makes it susceptible to natural disasters like earthquakes, tsunamis, and volcanic eruptions, which may impact its maritime borders.

The Solomon Islands shares a maritime border with Australia
Australia is unique in that no country borders it by land. However, several nations share maritime borders with Australia, including the Solomon Islands. The Solomon Islands is an archipelagic state situated in the southwest Pacific Ocean, approximately 2,000 km to the northeast of Australia. It has a land mass of 28,400 km2, extending over nearly 1,000 islands comprising nine main island groups. The capital, Honiara, is located on Guadalcanal, the largest island.
The Australia-Solomon Islands Maritime Boundary Agreement is a treaty between the governments of Australia and the Solomon Islands that was signed in Honiara on 13 September 1988. This treaty established a relatively short maritime boundary composed of two straight-line segments defined by three individual coordinate points. The boundary represents an approximate equidistant line between the two nations and defines the limit of the Australian Fishing Zone and the Solomon Islands Exclusive Economic Zone. The treaty entered into force on 14 April 1989 after ratification by both countries.
The Solomon Islands' primary maritime zones legislation is the Delimitation of Marine Waters Act 1978, which defines the baselines of the islands and its internal waters, archipelagic waters, territorial sea, and exclusive economic zone. The Declaration of Archipelagic Baselines within this Act states the geographical coordinates of the base points that define the five archipelagic groups in the Solomon Islands: The Main Group Archipelago, the Ontong Java Group Archipelago, and the Duff Islands Archipelago.
The maritime border between Australia and the Solomon Islands is an important aspect of the relationship between the two nations. Australia was the first country to establish diplomatic relations with the Solomon Islands upon its independence on 7 July 1978. The two countries have strong people-to-people links, shared democratic values, and a longstanding history of cooperation. Australia is an important economic partner for the Solomon Islands and is its largest development partner, supporting almost all areas of society and the economy, including health, justice, education, governance, gender, climate, infrastructure, and private sector development.
