The Twelve Apostles
What is The Twelve Apostles, and where is it?
The Twelve Apostles are limestone stacks rising from the Southern Ocean off Victoria's Great Ocean Road in Australia. Located within Port Campbell National Park, these towering formations were carved from ancient seabed deposits by millions of years of erosion and remain in constant transformation.
Location on Victoria's Southwestern Coast
The Twelve Apostles sit off the shore of Port Campbell National Park along Victoria's Great Ocean Road, in southeastern Australia. The coordinates place them at the edge of the Southern Ocean, where the coastline turns particularly dramatic. The stacks are accessible from the main viewing platform, though six of the seven remaining formations cluster together while the seventh stands several metres away. Their proximity to one another and to the road has made them a significant tourist destination.
The limestone unit underlying these formations, called Port Campbell Limestone, was deposited during the Mid-Late Miocene epoch, between 15 and 5 million years ago. This ancient seabed material now forms the cliffs and stacks visible today. The geological layer extends along this section of coast, creating the conditions for ongoing erosion and the eventual formation of new stacks from existing headlands.
How Waves and Weather Carved the Stacks
The Twelve Apostles were formed through a multi-stage erosion process driven by the Southern Ocean's harsh conditions. Waves and weather gradually wore away the soft limestone, first creating caves within the cliff face. These caves expanded into arches as erosion continued, and when the arches could no longer support their own weight, they collapsed. The result was isolated rock stacks, some reaching heights of 50 metres. This process unfolded over millions of years but continues today.
The stacks remain susceptible to further erosion from wave action. In July 2005, a 50-metre-tall stack collapsed, reducing the number of standing formations from nine to eight. Another collapse occurred in 2009, leaving seven stacks standing. The name 'Twelve Apostles' has never accurately reflected the actual count—there were likely only nine stacks at most. As erosion persists, existing headlands are expected to become new limestone stacks in the future, ensuring the landscape remains dynamic.
The Naming and Tourist Appeal
The stacks were originally called the Pinnacles and also known as the Sow and Pigs, with Muttonbird Island designated as the Sow and smaller stacks as the Piglets. The name was officially changed to the Twelve Apostles, referencing the Apostles of Jesus, despite the formations never having numbered twelve. This renaming was deliberate—chosen to attract more tourists to the site. The strategy succeeded, and the Twelve Apostles became one of Australia's most recognizable coastal landmarks.
The site's appeal rests on the dramatic visual impact of the stacks rising from the ocean and the accessibility of viewing platforms. The proximity of the formations to one another creates a striking composition, particularly when light catches the golden limestone. The Great Ocean Road itself draws visitors to the region, and the Twelve Apostles function as a major waypoint along this scenic route.
The Visible Stacks from the Main Viewpoint
From the most popular viewing platform, six of the seven remaining stacks are visible. The seventh stack is located several metres away from the corner of the main platform, requiring visitors to shift position to see it. This arrangement means that the classic photograph of the Twelve Apostles typically captures six formations rising from the water, their limestone faces weathered and fractured by millennia of exposure. The stacks vary slightly in height and shape, each bearing the marks of differential erosion.
The viewing platform itself has become a fixed reference point in the landscape. The positioning of the seventh stack relative to this platform is now documented in official descriptions, indicating how human infrastructure has become intertwined with how the site is experienced and understood. The arrangement also reflects the ongoing changes to the formation—the collapse of stacks in 2005 and 2009 altered which formations are visible from which vantage points.
Indigenous Ownership and Marine Protection
In March 2023, the Federal Court of Australia formally recognised the Eastern Maar people as traditional owners of 8,578 square kilometres of land in south-west Victoria, including the Twelve Apostles, under the Native Title Act of 1993. This legal recognition affirmed Indigenous connection to the landscape and its management. The decision reflects growing acknowledgment of Aboriginal and Torres Strait Islander peoples' relationship with Australian lands and waters.
Environmental protection efforts at the site have included opposition to seismic exploration. In 2002, the Port Campbell Professional Fishermen's Association blocked attempts by Benaris Energy to conduct seismic surveys, citing concerns about harm to marine life. The Victorian government subsequently prohibited seismic exploration at the site. These actions demonstrate how competing interests—tourism, fishing, resource extraction, and conservation—intersect at the Twelve Apostles.

Questions about The Twelve Apostles
Why are they called the Twelve Apostles if there were never twelve?
The name was officially adopted to attract tourists, despite the formations never numbering twelve. Historical records suggest there were likely only nine stacks at most. The name references the Apostles of Jesus and proved effective in drawing visitors to the site.
How tall are the Twelve Apostles stacks?
The stacks reach heights of up to 50 metres (160 feet). One stack of this height collapsed in July 2005, and another fell in 2009. The remaining seven stacks vary in height and continue to be shaped by wave erosion.
How old is the limestone that forms the stacks?
The Port Campbell Limestone was deposited during the Mid-Late Miocene epoch, between 15 and 5 million years ago. This ancient seabed material now forms the cliffs and stacks visible along the coast today.
How were the stacks formed?
Waves and weather from the Southern Ocean gradually eroded soft limestone, creating caves in the cliff face. These caves expanded into arches that eventually collapsed, leaving isolated rock stacks. This process continues today as erosion reshapes the landscape.
Who are the traditional owners of the Twelve Apostles?
The Eastern Maar people were formally recognised as traditional owners of the land including the Twelve Apostles in March 2023 by the Federal Court of Australia under the Native Title Act of 1993.

Which iconic coastal landmark features limestone stacks that inspired a biblical name despite never having the promised number?
The Twelve Apostles in Australia are named after twelve apostles, but erosion has continuously changed the number of visible stacks throughout history, so the name has never accurately reflected the actual count.

The Twelve Apostles is one of 266 places in Terravel. A new one every morning.
