Plunging over the edge of a columnar basalt lava flow, Big Millstream Falls is reputedly the widest single-drop waterfall in Australia. A walking track leads to a viewing area over the falls. Here, in the rainshadow of the eastern dividing ranges, the dry, open woodland vegetation is dominated by eucalypts. A separate entrance to the park takes you to Little Millstream Falls. View these beautiful falls from just near the carpark or take the steep and narrow track to their base. Millstream Falls National Park lies within the traditional country of the Jirrbal Aboriginal people. The Jirrbal lived in the rainforest in semi-permanent villages, and used the rainforest’s rich resources for food medicine and materials.
