Mt. Augustus is 450km east of Carnarvon. It reaches 1106 (one source says 1150) metres above sea level, 706 (some sources quote 858) metres above the surrounding plain, and from the top the surrounding country can be seen for up to 160 kilometres. It is 16km long and 5km wide.
The rock was named by F.T. Gregory in 1858 after his elder brother who later became Surveyor-General of Queensland. It is estimated to be over 1,750 million years old. It is twice the size of Ayres Rock (Uluru).
On the north side of the rock is the Lyons River and a permanent fresh water pool known as Cattle Pool.
Mount Augustus is a monocline (it is made up of more than one type of rock) as opposed to Uluru which is a monolith and is made of only one type of rock.
No campsites are available inside the park but a tourist complex has been established outside the park boundary about 5km from the rock.
