The Billimina Shelter is an excellent destination for a leisurely walk within the Grampians National Park.

The walk begins at the Buandik picnic spot and takes you through the Billimina Creek to the Buandik Falls.

From the falls, it’s just a short walk until you reach the shelter, which features a large rock that hangs over what was once a meeting place for the Jardwadjali people. The rock is covered in over 2,500 motifs made of red bar strokes.

It’s believed that these bar lines, seen in rows, were used to keep count of events, but another hypothesis is that the Jardwadjalj people used it to tell how long they spent at the shelter. Due to the animal remains and stone tools that were excavated here, scientists were led to believe that it was used to shelter the people from the harsh winters up to the early summer. Some of the paintings are also depictions of animal tracks and human stick figures.

In fact, this area has the highest concentration of rock art sites in Australia, with over 80% of Victoria’s rock art sites located here. There have been around 60 of these sites with more than 4,000 motifs identified within the park alone.
