The sea route passes through 9 seas
The sea route from Busan, South Korea, to Darwin, Australia, covers a distance of 3049 nautical miles and passes through nine seas. The journey takes about 12.7 days.
The first sea vessels departing Busan will traverse is the Sea of Japan. This sea is located in East Asia and is bordered by Japan, Russia, and the Korean Peninsula. It connects to the East China Sea and the Sea of Okhotsk, both of which are part of the Pacific Ocean.
The second sea along the route is the East China Sea, located in the Pacific Ocean between China and Taiwan to the west and Japan and the Ryukyu Islands to the east. It is a part of the Pacific Ocean and connects to the Sea of Japan and the Yellow Sea.
The third sea, the Philippine Sea, is a marginal sea of the Western Pacific Ocean located east of the Philippines. It extends over an area of approximately 5 million square kilometres and is bordered by the Philippines to the west, Taiwan to the north, and Guam to the east.
The North Pacific Ocean is the fourth sea along the route. It is the northern hemisphere's most extensive and deepest ocean basin, stretching from the Bering Sea in the north to the South China Sea in the south and from the east coast of Asia to the west coast of the Northern Americas.
The fifth sea, the South Pacific Ocean, is a vast body of water covering approximately 63.8 million square kilometres. It is bordered by many islands and archipelagos, including Australia, New Zealand, and the Pacific Islands.
The sixth sea along the route is the Ceram Sea, located in the Pacific Ocean, between the islands of Sulawesi, Manus, New Guinea, and the Moluccas.
The Banda Sea is the seventh sea along the route. It is one of the deepest seas in the world, with an average depth of about 4,248 feet. It is located in Indonesia and is bordered by the islands of Sulawesi, Manus, New Guinea, and Maluku.
The Arafura Sea is the eighth sea along the route. It is located between Australia and New Guinea and is connected to the Coral Sea and the Timor Sea.
The final sea along this route is the Timor Sea, located between Australia and Timor-Leste (East Timor). It is a relatively shallow sea, with an average depth of about 1,000 feet, and is home to a diverse range of marine life, including coral reefs and whale species.

The closest distance as the crow flies is 5292km
The distance between Busan, South Korea, and Darwin, Australia, is quite considerable, with the closest direct route, as the crow flies, covering 5,292 kilometers. This distance represents a straight line between the two points, ignoring any land or water obstacles. To put this distance into perspective, it is almost equivalent to flying from the west to the east coast of the United States. Imagine traveling from Los Angeles to New York City in a straight line; that's how far five thousand, two hundred and ninety-two kilometers is.
Now, if you were to travel by plane between Busan and Darwin, the distance may vary slightly depending on the specific flight path and any weather diversions, but it would generally be relatively close to this direct distance. Modern aircraft are designed to fly in the most fuel-efficient manner, so they tend to follow fairly direct routes, weather and air traffic control permitting. Of course, one must also consider take-off and landing patterns, which can add a little distance, but the overall path tends to be quite efficient and direct.
In practical terms, this distance would take a commercial aircraft several hours to cover, depending on head or tailwinds. The average speed of a typical passenger jet can vary, but a rough estimate would put the flight time at around seven to eight hours. This, of course, is a much faster and more time-efficient method of travel than alternatives like sea travel, which would take several days, if not weeks, to make the same journey.
While a direct flight is the quickest way to cover this distance, it is worth noting that this journey would also be possible by land and sea. One could, in theory, drive and take a car ferry, but this would be an epic journey, and the distance by road would be much longer, not to mention the time and cost involved. The distance by sea is also a viable option, with cargo ships and cruise liners making similar journeys, but again, the time taken would be significantly longer than a direct flight.
So, while 5,292 kilometers is the closest distance as the crow flies, the method of travel will always be a key factor in the time it takes to cover this ground. Whether by air, land, or sea, the journey from Busan to Darwin is a significant one, offering a unique and fascinating cultural experience at either end of this vast distance.

The closest sea port is Port Darwin
The closest sea port to Busan, South Korea, is Port Darwin in Darwin, Australia. The distance between the two ports is approximately 3049 nautical miles. Port Darwin has been in operation in several locations, including Stokes Hill Wharf, Cullen Bay, and East Arm Wharf, which opened in 2000. Panamax-sized ships with a maximum length of 274 metres and a DWT of up to 80,000 tonnes can use the port.
In 2015, the Northern Territory government leased Port Darwin to the Chinese-owned Landbridge Group for $506 million. The 99-year lease was granted by the then Country Liberal-controlled Northern Territory Government under Chief Minister Adam Giles. The transaction caused significant controversy in Australia, with bipartisan support to return the port to Australian ownership. The deal was criticised due to its strategic significance as part of China's Belt and Road Initiative and its proximity to a US Marine base and the jointly used Darwin International Airport.
In 2019, a proposal was launched by Federal Labor MP Nick Champion to renationalise the port and end Chinese control. However, a 2021 review found no national security grounds to overturn the lease. During the 2025 Australian federal election campaign, both major parties pledged to return the port to Australian ownership if elected. Despite this, the federal government announced in October 2023 that it would not cancel Landbridge's lease.
US private equity firm Cerberus has expressed interest in acquiring the lease for Darwin Port. A senior executive from Landbridge confirmed that a Cerberus executive had met with the port's CEO, but no discussions had taken place with the Landbridge board.

The closest airport is Darwin International Airport
The closest airport to Busan, South Korea, is the Darwin International Airport in Australia. This airport is a major gateway to Australia for international flights, providing easy access to and from Europe, America, and Asia.
Darwin International Airport has a rich history, serving as the primary domestic and international airport for the Northern Territory between 1950 and 1974. It was a significant stopover for airlines travelling between Australia and Asia and onwards to Europe. However, the introduction of long-range aircraft in the 1970s reduced the need for stopovers, leading to a decrease in airlines using the airport.
Despite this, Darwin International Airport has played a crucial role in various situations. During Cyclone Tracy in 1974, the airport facilitated the evacuation of 25,628 people from Darwin. In 1999, it was extensively utilised to support UN operations in East Timor, and it also assisted in medical evacuations following the 2002 Bali bombings.
Over the years, the airport has undergone significant expansions to accommodate growing passenger numbers. In 2008, the Australian Infrastructure Fund (AIX) announced a $60 million expansion plan, and in 2011, a $85 million expansion project was completed, doubling the airport's capacity during peak periods.
Today, Darwin International Airport continues to be an important hub for international travel, with various airlines offering direct flights to destinations like Singapore, Bali, Manila, and Kuala Lumpur. It provides a convenient gateway for travellers heading to or from Asia, Europe, or America, making it a strategic choice for those travelling to or from Busan, South Korea.
