Australia’s southern coast has the Red Rocks, which can reach 147 metres tall along the Great Ocean Road. They are one of the country’s most visited natural wonders, with over two million tourists each year.

### The Real Age of the Rocks
Many people think these giant rock piles were made millions of years ago. But a study published on April 24, 2026 shows that’s wrong. Scientists found that the rocks are only a few thousand years old.

### Scientific Discovery
Geologist Stephen Gallagher from Melbourne University and his team looked at tiny fossils inside the rocks. These fossils show that the limestone that makes up the rocks formed between 14 million and 8.6 million years ago. At that time, a shallow sea covered the southern coast of Australia. Sediments that fell to the sea floor hardened into limestone.

### The Effect of Glaciers
When glaciers melted 20,000 years ago, sea levels rose. The new sea came back to the shore and slowly eroded the soft limestone with waves. This process carved the coastline into cliffs, ledges, and eventually separate rock piles.

### History of the Rocks
At first, the formations were called “Sow and Piglets” (Carrot and Piglets). In the 1920s, they were renamed “Twelve Apostles” to boost tourism. Actually, there were only nine rocks at first. One fell in 2005, another in 2009, leaving seven today.

### What Will Happen Next?
Natural erosion will keep breaking the rocks down over time. Scientists study them before they disappear to learn about Earth’s climate, oceans, and coastlines. This knowledge helps us understand how future climate changes might affect us.

### Did You Know?
- Limestone is made from the shells of tiny sea creatures that settled in water.
- The red color of the rocks comes from minerals inside the limestone that reflect sunlight.
- Two million tourists visit Australia each year to see this natural wonder.

### Questions Kids Might Ask
1. **Why are the rocks red?** The minerals inside the limestone turn sunlight into red.
2. **When will the rocks fall?** Scientists estimate a few meters of erosion each year.
3. **Can we protect the rocks?** It’s hard to keep them completely safe, but limiting visitor numbers can slow erosion.

### Why This Matters to Kids
This story teaches children how nature works, the effects of climate change, and how scientists track these changes. It also highlights the importance of protecting nature.

### Summary
Australia’s famous Red Rocks are actually young, formed by glacier melt 20,000 years ago. Scientists study them to learn about Earth’s past and future, helping us prepare for climate changes.

### Looking Ahead
Watching the erosion of the rocks helps scientists make better climate predictions and reminds kids of the importance of caring for nature.
