Australia is the largest landmass with its antipodes entirely in the ocean. This means that if you were to dig a hole straight through the earth from anywhere on the Australian mainland, you would end up in the ocean. However, some locations in mainland Australia and Tasmania are close to being antipodes of islands in the North Atlantic Ocean, such as Bermuda, the Azores, and Puerto Rico. The antipodes of Australia's most populous city, Sydney, is Almagreira, an island in the Azores, Portugal.

The antipodes of Australia are in the North Atlantic Ocean
Antipodes are points on the Earth's surface that are diametrically opposite to each other. In other words, if you were to dig a straight tunnel through the Earth from one point, you would emerge on the other side at its antipode. The antipodes of Australia are unique in that they lie entirely in the North Atlantic Ocean. This means that if you were standing anywhere on the Australian mainland and dug straight through the Earth, you would emerge in the ocean on the other side.
While Australia's antipodes lie in the ocean, some locations on the Australian mainland and Tasmania are close to having antipodes on land. These include the islands of Bermuda, the Azores, and Puerto Rico in the North Atlantic Ocean. For example, Flores Island, the westernmost island of the Azores, is nearly antipodal to Flinders Island, located between Tasmania and the Australian mainland.
The closest antipodal city to Sydney, Australia, is Almagreira in the Azores, Portugal. The distance between these two points is approximately 20,000 kilometers, and there are no non-stop commercial flights between them. To travel between any pair of antipodes, one would have to take a multi-stop flight or hypothetically, tunnel straight through the Earth's center.
It is worth noting that the majority of locations on land do not have land-based antipodes. This is because most of the Earth's landmass is in the Northern Hemisphere, while most of its water is in the Southern Hemisphere. As a result, the antipodes of many landmasses are in the ocean, and vice versa. For example, the North Pole and South Pole are antipodes, as are parts of the Pacific Ocean off the coast of Peru and Southeast Asia.

The opposite side of Sydney, Australia is Almagreira, Azores, Portugal
The opposite side of the world from Sydney, Australia, is Almagreira, a parish in Vila do Porto, Azores, Portugal. Almagreira is the closest city to Sydney's antipodal point, with a distance of about 20,000 kilometres between them. This distance makes Sydney and Almagreira the farthest cities from each other in the world. While there is no direct commercial flight route between the two cities, a direct flight would take around 22 hours.
Almagreira is located on Flores Island, the westernmost island of the Azores. The Azores are a group of nine major islands and an islet cluster, extending for more than 600 kilometres in a northwest-southeast direction. All of the islands have volcanic origins, and the region is seismically active, lying at the junction of the North American, Eurasian, and Nubian plates.
The local population of Almagreira has traditionally been involved in agriculture, cattle-raising, and artesian handicrafts. The region is also known for its unique white sand beaches along its southern margins, attracting tourists from within and outside the Azores.
It is interesting to note that Australia is the largest landmass with its antipodes entirely in the ocean. This means that if you were to travel through the Earth from Sydney to its antipodal point, you would end up in the ocean near Almagreira, Azores, Portugal.

The Australian mainland is the largest landmass with its antipodes entirely in the ocean
The antipodes of a location are the points on the Earth's surface that are diametrically opposite to it. In other words, if you were to dig a straight tunnel through the Earth from a certain point, you would emerge on the other side of the world at its antipodes. The Australian mainland is the largest landmass whose antipodes are entirely in the ocean.
It is a common belief in Europe and America that the exact opposite side of the world is China. However, this is only true for certain parts of Argentina and Chile. In reality, most locations in the Northern Hemisphere, including Europe and the United States, have antipodes that lie in the ocean. For example, the antipodes of North America are in the Indian Ocean, between Australia and Africa.
While the Australian mainland does not have any antipodes on land, some locations in mainland Australia and Tasmania come close. For instance, Flores Island, the westernmost island of the Azores, is nearly antipodal to Flinders Island, located between Tasmania and the Australian mainland. Similarly, the Australian city of Sydney is antipodal to Almagreira in the Azores, Portugal, with the latter being the farthest city from Sydney.
The largest landmass with antipodes entirely on land is the island of Borneo, whose antipodes lie in the Amazon rainforest.

The longest non-stop scheduled airline flight is between Singapore and Newark, New Jersey
The opposite side of the world from Australia is the North Atlantic Ocean. Some cities on the other side of the world from Australia include Almagreira, Azores, Portugal, and Flores Island, the westernmost island of the Azores.
Now, onto the longest non-stop scheduled airline flight in the world, which is between Singapore and Newark, New Jersey. This route, operated by Singapore Airlines, covers 9,535 miles in 18 hours and 25 minutes. The flight number is SQ21/SIA21, and it takes off from Newark Liberty International Airport (EWR) at 23:00 EDT and lands at Singapore Changi Airport (SIN) at 4:05 SGT. The return flight, SQ22/SIA22, covers 10,691 miles and takes 17 hours and 45 minutes.
The Airbus A350-900ULR is the aircraft of choice for this route, with a maximum range of 11,200 miles. This plane was specifically designed for long-haul flights, with increased fuel capacity and improved comfort features. The flight typically has four pilots and 13 flight attendants on board.
The SQ21/SIA21 flight from Newark to Singapore passes within 130 kilometres of the North Pole and operates as a red-eye flight, with a morning departure from Singapore. The SQ22/SIA22 return flight from Singapore to Newark takes a route over Asia and Alaska and benefits from assistance from prevailing high-altitude winds, which make the flight time slightly shorter despite the greater distance.
Singapore Airlines first introduced this record-breaking route in June 2004, using the Airbus A340-500. The airline discontinued the route in November 2013 due to low revenue but relaunched it in October 2018 using the Airbus A350-900ULR.

The North Pole and South Pole are antipodes
Antipodes are defined as the points that are diametrically opposite to each other on the Earth, with a line drawn between them passing through the Earth's centre. The antipodes of a location can be calculated by converting the latitude of the place to the opposite hemisphere and subtracting the longitude from 180°, then converting the result to the opposite hemisphere.
The Australian mainland is the largest landmass with its antipodes entirely in the ocean. Some locations on the Australian mainland and Tasmania are close to being antipodes of islands in the North Atlantic Ocean, such as Bermuda, the Azores, and Puerto Rico. The antipode of Sydney, Australia, is Almagreira, Azores, Portugal.
The majority of locations on land do not have land-based antipodes. This is due to the Southern Hemisphere having comparatively less landmass than the Northern Hemisphere. For example, the antipodes of Australia are in the North Atlantic Ocean, while the antipodes of southern Africa are in the North Pacific Ocean.
