Go inside Australia’s deepest mine and explore the extreme underground world of Mount Isa’s Enterprise Mine, nearly 2km beneath the surface. Discover how miners survive lethal heat, rock pressure, and one of the most challenging engineering environments on Earth, while uncovering the ancient geology behind one of Australia’s richest copper, lead, zinc, and silver deposits.
In 2013, headlines claimed the Arckaringa Basin near Coober Pedy could contain up to 233 billion barrels of shale oil, triggering comparisons to Saudi Arabia and raising the possibility that Australia had discovered one of the largest unconventional oil resources on Earth. But was this truly Australia’s forgotten oil mega-discovery, or just an overhyped shale estimate that never stood up to scrutiny? This geology deep dive explores the petroleum geology of the Arckaringa Basin, the controversial Coober Pedy oil discovery claims, the difference between oil in place and recoverable reserves, and why hydraulic fracturing would have been essential to unlock this remote South Australian resource. From Linc Energy’s trillion-dollar claims to environmental controversy, failed momentum, and the basin’s modern pivot toward helium and natural hydrogen exploration, this is the full story behind Australia’s abandoned outback oil dream.
Beneath the forests of Tasmania lies Australia’s deepest known cave system. Descending more than 400 metres underground, Niggly Cave preserves ancient rivers, hidden chambers, and geological history stretching back hundreds of thousands of years. This documentary explores the formation of the Junee–Florentine karst, the extreme vertical shafts hidden beneath Mount Field, and the forgotten underground world that almost nobody knows exists.
A magnitude 4.5 earthquake struck near Orange, New South Wales in April 2026, becoming the largest recorded in the Cadia region in years. This unusually shallow earthquake was felt up to 300 km away, raising serious questions about whether mining at Cadia Valley Operations may have triggered the event. This video explores the science behind shallow earthquakes, fault reactivation, and how large-scale gold mining operations can redistribute stress in the Earth’s crust. Was this earthquake purely natural, or could human activity have played a role? Dive into Australian geology, seismic activity in NSW, and the real mechanics behind mining-induced earthquakes.
Discover the incredible geology behind Coober Pedy, the world’s largest opal field and one of the strangest towns on Earth. In this episode, we uncover how an ancient inland sea within the Great Artesian Basin created the perfect conditions for opal formation, and why this barren desert is filled with hidden treasure. Learn how silica-rich groundwater formed opal over millions of years, why deposits are so unpredictable, and how this unique geology led to one of Australia’s most fascinating mining towns.
The Finke River, also known as the Larapinta, is widely regarded as the oldest river in the world and one of the most extraordinary geological features in central Australia. Flowing across the MacDonnell Ranges in the Northern Territory, the Finke River preserves an ancient drainage pathway that may date back to the late Paleozoic, making it older than the dinosaurs. This blog explores how the Finke survived the Alice Springs Orogeny, deep Cretaceous weathering, etchplanation, tectonic tilting, and extreme desert floods to remain one of the longest-persisting river systems on Earth. From Glen of Palms paleomeanders to the Missionary Plain and the Lake Eyre Basin, we break down the geomorphology, tectonics, and climate history that shaped Australia’s most famous ancient river.
Australia’s richest gold mine isn’t built on classic quartz veins. This deep-dive into the Boddington Gold Mine explains how intrusion-hosted gold and copper formed, why Boddington produces more gold than any other mine in Australia, and how billions of dollars in metal were hidden beneath laterite in Western Australia. Discover the geology, mining history and economic significance of one of the world’s most unusual Archean gold deposits.
Beneath the landscapes of the Northern Territory lies the eroded core of an ancient volcanic arc that once shaped the edge of Australia nearly two billion years ago. The Pine Creek Orogen preserves the deep roots of a Paleoproterozoic subduction system, where magma was generated, crust was deformed, and metal-rich fluids circulated through the Earth’s crust. Unlike modern volcanic arcs marked by active volcanoes, this system has been stripped down by immense geological time, exposing granites, metamorphosed sediments, and structural pathways that reveal how continental crust grows. This article explores how volcanic arcs form, why Australia preserves only their roots, where the Pine Creek Orogen is located, and how these deep processes led to the concentration of gold and uranium that made the region one of Australia’s most important mineral provinces.
Hidden in the far north of Australia is one of the continent’s most overlooked geological oddities. Near Jarnem in the Northern Territory, a field of sandstone pinnacles and dome-shaped rock formations rises from the landscape, forming what looks like a ruined stone city carved by design. These formations are not man-made and are not related to Australia’s famous limestone Pinnacles or the Bungle Bungles, despite their visual similarity.
Formed from Devonian to Early Carboniferous sandstones more than 300 million years ago, the Jarnem Keep landscape represents the remains of an ancient sandstone surface that once stretched across northern Australia. Over millions of years, deep chemical weathering weakened the rock before erosion stripped away vast volumes of stone, leaving behind isolated towers, ridges and domes. This landscape is defined by erosion and loss rather than construction, making it one of Australia’s most unusual geological environments.
Today, Jarnem Keep stands as a rare example of a landform shaped by subtraction, where the spaces between the pinnacles tell as much of the geological story as the rocks themselves. It is a hidden geological landmark that reveals how climate, erosion and time can quietly erase entire landscapes while leaving behind only their strongest remnants.
Deep beneath the deserts of central Australia lies a billion-year-old supervolcano that changed everything we know about how Earth works. The Talbot Sub-basin in the Musgrave Province produced colossal eruptions that rivaled Yellowstone and Toba — but unlike them, it wasn’t powered by a deep mantle plume. This was a supervolcano born from crustal heat, rewriting the rules of geology and proving that continents themselves can generate planet-shaping eruptions.
Hidden beneath the waters off Western Australia lies the Perth Canyon — a colossal underwater gorge often called Perth’s Grand Canyon. This blog dives deep into the canyon’s stratigraphy, revealing how ancient rivers, tectonic rifting, and submarine landslides carved one of the largest submarine canyons in the Southern Hemisphere. From the Late Cretaceous formation of the Vlaming Sub-basin to the discovery of fossil coral reefs in its depths, the Perth Canyon tells a 70-million-year story written in stone. Explore how sea level changes, continental drift, and powerful submarine currents shaped this underwater landscape into a geological masterpiece — a time capsule of Australia’s dynamic Earth history.
Ninety million years ago, Victoria, Australia erupted after more than 200 million years of silence. This blog dives into the story behind the mysterious Older Volcanics Province — the ancient eruptions that transformed southeastern Australia and marked the breakup of Gondwana. Discover how the opening of the Tasman Sea, continental rifting, and decompression melting deep in the Earth’s mantle triggered Victoria’s fiery awakening, and why this long-extinct volcanic province still matters to Australian geology today.
Rising 50 metres from the desert plains of Central Australia, Chambers Pillar is one of the Northern Territory’s most fascinating geological landmarks. This ancient sandstone monolith has survived over 350 million years of erosion, standing as a testament to the power of time and the natural forces that shaped Australia’s red heart. Discover the story behind its formation, its cultural significance to the Arrernte people, and why it remains one of the most extraordinary natural wonders in the Australian outback.
Hidden in the plains of New South Wales lies one of Australia’s rarest geological treasures — the Fifield platinum field. Over a century ago, prospectors uncovered something almost impossible: real platinum nuggets, heavier than gold, gleaming in ancient riverbeds. This forgotten discovery reveals a story that stretches back 440 million years, from the birth of platinum deep in magma to its journey through erosion, weathering, and rediscovery in the Australian outback.
Over half a billion years ago, northern and western Australia were engulfed by a cataclysmic volcanic event that reshaped the continent and may have driven one of the first great extinction events in Earth’s history. Known as the Kalkarindji Large Igneous Province, this ancient eruption flooded more than two million square kilometres of land with molten basalt, releasing vast amounts of volcanic gases into the atmosphere. In this article, we explore how the Kalkarindji eruption began, how it spread across Gondwana, and how it changed the planet’s climate and life forever.
Hidden deep in Australia’s Red Centre, the Petermann Ranges are among the oldest mountain chains on Earth. Formed over 550 million years ago during the Petermann Orogeny, these rugged ranges tell the story of massive geological forces that once rivaled the Himalayas.
Unlike more familiar mountain belts, the Petermann Ranges are remnants of an intra-continental collision—where central Australia buckled under pressure from opposing landmasses. Today, these low-slung yet striking ranges offer a rare glimpse into Proterozoic tectonics, metamorphic belts, and some of the oldest exposed rocks on the continent.
Geology enthusiasts visiting this region will find ancient gneisses, granulites, and evidence of intense crustal uplift, all surrounded by sweeping desert landscapes.
Jutting out into the Tasman Sea like the jagged spine of a prehistoric creature, Cape Hauy (pronounced hoy) is a geological marvel on the Tasman Peninsula. The cape’s signature vertical dolerite columns rise abruptly from the ocean, forming some of the tallest sea cliffs in the Southern Hemisphere. These striking formations are remnants of Jurassic-aged dolerite intrusions that cooled slowly beneath the Earth’s surface and were later exposed by relentless coastal erosion.
Cape Hauy is part of the larger Tasman National Park, which also includes the famed Three Capes Track—a multi-day hike that offers panoramic views of sea stacks like the Candlestick and Totem Pole, two iconic dolerite pillars prized by climbers. This coastline isn’t just visually breathtaking—it also tells a dramatic story of Australia's deep-time volcanic activity and the slow sculpting power of the Southern Ocean.
