Aussies, How did the rocks at remarkable rocks park get there?

Those are some cool rocks. One of them is like dinosaur skull.

At first I thought they were smaller than people but when I looked at the left of the picture, I was quite surprised.

It took 500 million years for rain, wind, and pounding waves to create these aptly named granite boulders which are now part of the Flinders Chase National Park.

Steve Waugh made them.

Erosion. Don't have to be an Aussie to know that. It is the same type of rock above as below. As they eroded, they fell apart. Same truth most places.
