Chelodina Siebenrocki is commonly known a the dinner-plate turtle. It was named after the Austrian herpetologist Friedrich Siebenrock. They are the least known of the Australian turtles and one of the smallest members of the long-necked turtles of this genus.They are small to medium-sized, with oval shaped carapace growing to about 11 inches with its neck about half the length of the shell. Males are smaller than females. They are side-necked turtles, meaning they tuck their head partially around the side of their body when threatened instead of directly backwards. They are classified by the IUCN as near threatened. The international live animal trade had placed some pressure on this restricted-range species, especially in Indonesia.
