Whilst researching a project I have come across the highest sand dune in the world. It is in Eastern Algeria in the Sahara Desert and it is 465 metres above the plain. The longest sand dunes are found in the Simpson Desert at 200 kilometres on length.

I visited a dune in Namibia once which is 340 metres in height above the plain.

In comparison Big Red crossing point is about 30 metres above the plain and the highest point of the dune is 90 metres above seal level. The highest dune crossing on the Canning Stock Route meaures out at 17 metres above the track.

Don't have any figures on Canunda NP at Beachport or Fraser Island as there are some large dunes in those areas. The dunes in the southern part of the Nuytsland Nature Reserve in WA called Bilbunya Dunes I will be measuring later this year..hopefully. According to Member Davoe who recently visited there, they are quite spectacular.
