Kakadu Rock Art: 5,000 Sites, One Story

In Brief: Kakadu National Park in Australia's Northern Territory is home to more than 5,000 rock art sites, making it one of the richest collections of ancient rock art on Earth. The art spans tens of thousands of years and includes X-ray paintings, contact art, and works made with pigments ground from the land itself.

G'day, explorers! This month, Dusty and Boomer have landed somewhere truly extraordinary — and this is the kind of place that makes you stop, look up at a sandstone cliff, and feel like time itself has pressed pause.

Kakadu National Park is enormous. It covers nearly 20,000 square kilometres in Australia's Northern Territory, and deep within its rocky escarpments and shaded overhangs, there are more than 5,000 recorded rock art sites. Some of the paintings here are estimated to be over 20,000 years old — created long before the pyramids, long before written language, long before almost everything we call "history."

This is the first in our Kakadu series, and it's a big one. Pull up a seat — Dusty's got stories to share.

What is Kunbim, and Why Does It Matter?

The rock art of Kakadu is known as kunbim in the local Bininj Mungguy language. It is not simply decoration. Kunbim is a living record — a way of passing knowledge from one generation to the next, painted directly onto the land itself.

These artworks were made by the ancestors of the Bininj and Mungguy peoples, who have lived in this region for at least 65,000 years, making them one of the longest continuing cultures on Earth. The art tells stories about animals, spiritual beings, ceremonies, and daily life. Many sites are still considered sacred today.

For the children receiving this month's True Blue Pen Pals envelope, this is their introduction to one of the oldest storytelling traditions in the world.

What is X-Ray Art — and How Was It Made?

One of the most jaw-dropping styles found in Kakadu is X-ray art. These paintings show the inside of animals and humans — their bones, organs, and even the food inside their stomachs. Barramundi, kangaroos, turtles, and echidnas all appear in extraordinary anatomical detail.

X-ray art began appearing in Kakadu around 2,000 years ago. Artists used it to show spiritual knowledge and to teach younger generations about the animals they hunted and respected.

The paints used to create these works were made entirely from the land:

• Red and yellow ochre came from iron-rich rocks, ground into powder
• White pigment came from pipe clay or kaolin
• Black came from charcoal or manganese

These pigments were mixed with water, animal fat, or plant sap, then applied using fingers, sticks, feathers, or hollowed reeds used as early spray tools. Incredibly, many of these paintings have survived tens of thousands of years — partly because of the sheltered overhangs, and partly because of the binding power of the natural materials used.

Contact Paintings: When Sailing Ships Appeared on the Cliffs

Here is where the story gets particularly fascinating. Among the thousands of ancient images, there are paintings of tall-masted sailing ships.

These contact paintings date to the 1600s–1800s, when Macassan traders from what is now Indonesia sailed to northern Australia each year to harvest sea cucumbers (called trepang). Later, European explorers and settlers arrived by ship too.

The artists painted what they saw — extraordinary, towering vessels unlike anything from their own world. These contact paintings are a living timestamp: proof that the tradition of recording the world through kunbim never stopped, even as the world around it changed dramatically.

This is exactly what makes Kakadu's rock art so remarkable. It is not a frozen record from the distant past. It is a continuous story — one that kept being told across thousands of generations.

Two Sites Every Explorer Should Know

Ubirr and Nourlangie (Burrungkuy) are the two most visited rock art sites in Kakadu. Both are accessible by walking trails, making them perfect for families exploring the park.

At Ubirr, you can see X-ray fish, a Thylacine (Tasmanian tiger — extinct on the mainland for thousands of years), and contact-era figures. At Nourlangie, the Lightning Man (Namarrgon) watches from the cliff face — a powerful ancestral being said to create the fierce storms that roll across Kakadu each wet season.

Why the Story Never Stopped Being Told

Many ancient art traditions faded when the cultures around them were disrupted. Kakadu's didn't — and that is because the Bininj and Mungguy peoples maintained their connection to Country through one of the longest unbroken cultural traditions anywhere on Earth.

Today, Traditional Owners, park rangers, and cultural custodians work together to protect and interpret these sites. Some are repainted in the traditional way, keeping the stories alive with fresh colour. Others are monitored carefully to ensure they survive for future generations.

This is not a relic. This is a living story — and now it has been delivered to your letterbox, too.
