What You'll Learn
Indonesia borders Australia to the northwest
Indonesia is one of Australia's neighbouring countries to the north, along with East Timor and Papua New Guinea. To the north-east of Australia are the Solomon Islands, Vanuatu, and New Caledonia. New Zealand is located to the south-east of Australia.
The maritime border between Australia and Indonesia was agreed upon in a treaty signed in 1997. This treaty was the result of negotiations between the two countries to determine the location of their shared border. The process was challenging due to the potential impact on Indonesia's access to oil reserves in the region.
The proximity of Indonesia and Australia has influenced their relationship. Both countries have had disputes over sharing natural resources, particularly oil and gas located in the border region. Despite these challenges, Australia has strong bilateral relations with its neighbouring countries, providing significant foreign aid and investments to support their development.

Papua New Guinea is north of Australia
Papua New Guinea is located north of Australia. The two countries share a maritime border, with Australia extending to the southern shores of Papua New Guinea. They are also close neighbours, with Papua New Guinea being one of Australia's closest neighbours.
Papua New Guinea is a sovereign state, having gained independence from Australia in 1975. In 1978, the two countries signed a treaty that defined their maritime border. This treaty addressed the boundary challenges that affected the lives of the native people in the region. Australia has several outlying islands that are within Papua New Guinea's side of the border.
The relationship between Australia and Papua New Guinea is significant due to their proximity and shared history. Australia once ruled Papua New Guinea, and even after its independence, the two countries continue to maintain relations. The maritime border between them is crucial as it allows access to the rich resources located in those regions.
Papua New Guinea's location to the north of Australia is a result of their geographical positions in the Southern Hemisphere. Australia, being the smallest continent, is situated between the Indian and Pacific Oceans. Papua New Guinea, on the other hand, is located northeast of Australia, separated by the Coral Sea and the Torres Strait.

New Zealand is southeast of Australia
Australia is the smallest continent and one of the largest countries on Earth. It is situated in the Southern Hemisphere, neighbouring the Indian and Pacific Oceans. Australia is a sovereign country with a unique variety of flora and fauna.
New Zealand is located to the southeast of Australia. The Tasman Sea separates the two countries. Australia and New Zealand signed a treaty in 2004 to establish their official border, which came into effect in 2006. This treaty was an official recognition of the borders that the two countries had adhered to since the 1980s.
New Zealand is a close neighbour of Australia, and the two countries share strong bilateral relations. Australia contributes significantly to New Zealand in terms of foreign aid and investment. The relationship between the two nations is important and valued by both sides.
In addition to New Zealand, Australia shares maritime borders with several other countries, including Indonesia, East Timor, Papua New Guinea, the Solomon Islands, and New Caledonia. These countries are located to the north and northeast of Australia. Australia has a unique position as it does not share its continent with any other country, allowing for the development of its singular flora and fauna.

The Solomon Islands are maritime neighbours of Australia
The Solomon Islands archipelago is part of two distinct terrestrial ecoregions. Most of the islands are part of the Solomon Islands rainforests ecoregion, which also includes the islands of Bougainville and Buka. The Santa Cruz Islands are part of the Vanuatu rainforests ecoregion, together with the neighbouring archipelago of Vanuatu. The islands have a humid, ocean-equatorial climate with a mean temperature of 27°C.
Australia was the first country to establish diplomatic relations with the Solomon Islands upon the latter's independence in 1978. The two countries have strong people-to-people links, shared democratic values, and a longstanding history of cooperation. They continue to work together through security cooperation programs such as the RSIPF – AFP Policing Partnership Program (RAPPP) and the Defence Cooperation Program (DCP).
The maritime boundary between Australia and the Solomon Islands was signed in 1988 and came into effect the following year. The two countries have strong bilateral relations, with Australia contributing significant quantities of foreign aid to the Solomon Islands.

Australia shares a border with East Timor
Australia's border with Timor-Leste is a relatively new development, with Timor-Leste gaining independence in 2002. Prior to this, the border region was contested, with Indonesia also laying claim to the territory. The final treaty signed in 1997 between Australia and Indonesia included elements of both countries' arguments to determine the location of the border. This treaty was important not only for establishing clear boundaries between the nations but also for addressing the concerns of the native people in the region.
Australia's maritime borders are of great importance due to the vast quantity of resources located in those regions. The country has a strong interest in clearly defined borders with its neighbouring countries, which also include Indonesia, Papua New Guinea, the Solomon Islands, New Caledonia, and New Zealand. Australia has signed treaties with many of these nations to establish and recognise official maritime borders.
The relationship between Australia and Timor-Leste has not always been smooth, with disputes over natural resources causing tensions. However, the two countries have worked together to resolve these issues, and Australia has also contributed to Timor-Leste's development through foreign aid. The establishment of the permanent maritime border between the two nations was a significant step forward in their relations, providing a framework for cooperation and the sharing of resources.
