What You'll Learn

Australia's coastline is the sixth longest in the world
Australia has the sixth-longest coastline in the world. The coastline of Australia includes the coasts of mainland Australia and Tasmania, as well as a part of all Australian states and territories. The exact length of Australia's coastline is difficult to determine due to the coastline paradox, which states that a coastline does not have a well-defined length. The smaller the scale interval used to measure a coastline, the more detailed the measurement, and the longer the coastline will be.
According to The World Factbook, Australia's coastline is 25,760 kilometres (16,010 miles) long. However, this figure may not include all of Australia's coastal islands, of which there are many thousands. Including these islands, Australia's coastline is over 47,000 kilometres long. Another estimate places the length of Australia's coastline at 36,735 kilometres, while Geoscience Australia reports a length of 33,000 kilometres. These varying estimates can be attributed to the scale and methodology used for measurement, as well as the dynamic nature of coastlines, which are subject to change over time due to factors such as erosion and sea-level rise.
The Australian coastline is where three of the world's great oceans meet: the Pacific, Indian, and Southern Oceans. The coastline is characterised by a diverse range of landscapes, including broad sandy beaches, rocky cliffs, and mangrove swamps. It is estimated that over 10,000 beaches dot the Australian coastline, and approximately 50% of the Australian population resides within seven kilometres of the coast. The beach holds a special place in the Australian identity, serving as a place of interaction and cultural exchange for people from all over the world.
The management of Australia's coastline is of utmost importance, given the country's reliance on its coasts and estuaries for economic, social, and environmental benefits. Accurate and consistent mapping of the coastline is critical for characterising and managing coastal change, and new technologies, such as satellite earth observation and tidal modelling, are aiding in this endeavour.

The coastline is made up of mainland Australia and Tasmania
Australia has the sixth-longest coastline in the world, at approximately 25,760 kilometres (16,010 miles) according to The World Factbook. The World Resources Institute, on the other hand, estimates the coastline to be 66,530 kilometres (41,340 miles) long. The coastline of Australia comprises the coasts of mainland Australia and Tasmania, as well as numerous islands. In fact, almost 40% of the total coastline length comprises island coastlines.
The mainland coastline of Australia is quite diverse, with rugged and remote sections, such as the west coast of Tasmania, which is known for its high-energy beaches and strong winds, to more protected areas like the east coast of Tasmania, which is shielded from the full brunt of the weather systems. The mainland coastline also includes popular tourist destinations such as the Great Barrier Reef, located off the coast of Queensland, and the famous surf beaches of the Gold Coast and Sunshine Coast in the same state.
Tasmania, the only island state of Australia, has a coastline that is approximately 3,030 kilometres long. This includes 2,237 kilometres of mainland coastline and 793 kilometres spread across five main islands. Tasmania offers a unique beach experience with dramatic landscapes and long expanses of coastline. The west coast, for example, is characterised by its raw and rugged nature, with some of the highest-energy beaches in the world, while the south coast is known for its bays, harbours, and low-energy waves.
The length of Australia's coastline is not a fixed number and can vary depending on the scale of the maps used for measurement. New technologies will allow for more detailed measurements, resulting in longer coastline lengths. The method of measurement can also impact the calculated length, as coastlines behave like fractals, exhibiting different lengths at different scale intervals. This "magnifying" effect is more pronounced for convoluted coastlines, such as those with many islands and inlets, which Australia possesses in abundance.

There are over 10,000 beaches along the coastline
Australia has a coastline that is approximately 25,760 kilometres (16,010 miles) long according to The World Factbook. However, the World Resources Institute estimates the coastline to be 66,530 kilometres (41,340 mi) long. The coastline paradox states that a coastline does not have a well-defined length. Measurements of the length of a coastline behave like a fractal, differing at various scale intervals. The smaller the scale interval, the more detailed the measurement, and the longer the coastline will be.
Australia's coastline includes the coasts of mainland Australia and Tasmania, as well as numerous smaller islands. The mainland and Tasmania are surrounded by thousands of small fringing islands and several larger ones. Approximately 40% of the total coastline length is made up of island coastlines. The coastline of Australia is where three of the world's great oceans meet: the Pacific, Indian, and Southern Oceans.
Australia has over 10,000 beaches along its coastline, with estimates ranging from 10,685 to 11,761 beaches. If an individual visited one beach per day, it would take them over 32 years to visit all of them. The beaches in Australia vary in length, with some being a couple of hundred metres long and separated by rocky outcrops, while others are much longer, such as the 194-kilometre-long sandy beach on the Younghusband Peninsula in South Australia, known as The Coorong.
The abundance of beaches in Australia is due to the country being entirely surrounded by the ocean. Beaches are popular destinations for both locals and travellers, as over 85% of Australians live on the coast and most of the country has a warm temperate or subtropical climate. Australia has a prominent beach culture, often considered part of its national identity, with various television shows, movies, and songs being set in or relating to beaches.

The Australian Capital Territory is the only landlocked state
Australia has a coastline that is approximately 25,760 kilometres (16,010 miles) long, according to The World Factbook, making it the sixth-longest coastline in the world. The World Resources Institute, on the other hand, estimates the coastline to be 66,530 kilometres (41,340 miles) long, which would still place Australia sixth globally. The coastline comprises the coasts of mainland Australia and Tasmania, including all Australian states and territories.
Despite Australia's extensive coastline, the Australian Capital Territory (ACT) is notably the only landlocked state. ACT, located in southeastern Australia, is an internal territory that hosts the country's capital, Canberra. Canberra is situated within the territory and serves as the territory's primate city. The territory was transferred from New South Wales to the federal government in 1911, and Canberra was officially named the capital in 1913. While the majority of the territory's population resides in Canberra, ACT also includes towns such as Williamsdale, Oaks Estate, Uriarra, Tharwa, and Hall, as well as the Namadgi National Park.
Being landlocked, ACT does not have direct access to the ocean, which can have political, military, and economic implications. Landlocked countries often face challenges in trade and development due to limited access to international waters. However, it is important to note that ACT has a coastal enclave at Jervis Bay Territory, providing some level of access to the coast.
ACT has a locally elected legislative assembly that has governed the territory since 1988, with the Commonwealth maintaining authority and the power to overturn local laws. The territory hosts significant institutions, including the Parliament of Australia, the High Court of Australia, and numerous government agencies and foreign embassies. It is also home to several major universities, including the Australian National University, the University of Canberra, and the University of New South Wales.
In conclusion, while Australia boasts an impressive coastline that ranks among the longest in the world, the Australian Capital Territory stands out as the only landlocked state. ACT navigates the challenges of its landlocked status while serving as the nation's capital territory and housing important governmental, educational, and cultural institutions.

The coastline is constantly changing
Australia has a vast, diverse and dynamic shoreline that is constantly changing. The coastline is approximately 25,760 kilometres (16,010 mi) long according to The World Factbook, while the World Resources Institute estimates it to be 66,530 kilometres (41,340 mi) long. The coastline comprises the coasts of mainland Australia and Tasmania, along with numerous smaller fringing islands.
The Australian coastline is subject to various environmental factors that contribute to its constant state of change. One significant factor is the impact of the ocean and its processes. The coastline is influenced by wave action, tides, and coastal currents, which can lead to erosion, transportation, and deposition of sediment. The diverse nature of Australia's coastline, ranging from rocky cliffs to sandy beaches, means that different sections of the coast will be affected differently by these processes.
Another factor influencing the changing coastline is sea-level rise due to climate change. Scientific observations indicate that global warming will lead to rising sea levels, which will have significant impacts on Australia's low-lying coastal areas. The dynamic nature of the coastline, with its varying rates of change, makes it challenging to predict the exact consequences of sea-level rise. However, it is expected that some beaches may recede by hundreds of metres over this century.
To monitor and understand these changes, organisations like Geoscience Australia have employed satellite technologies, such as Landsat, to map and analyse the shoreline. These satellite images provide valuable insights into the annual shoreline locations, helping to identify coastal trends and dynamics.
The constant change of Australia's coastline has significant implications for coastal management and the country's overall well-being. With a large proportion of the population living in coastal regions and relying on the coast for various economic and environmental purposes, adapting to the changing coastline is crucial. This includes assessing the risks posed by erosion and inundation, as well as the potential loss of beaches, and implementing measures to protect and preserve the dynamic and diverse shoreline.
