EASTERN SNAPPING TURTLE Elseya latisternum Gray, 1867
This 20 cm tortoise is found throughout coastal Queensland and northern NSW.
It is found in various types of watercourse, but is most common in medium to large and fast flowing rivers, where it is sometimes found in relatively large numbers. This species feeds on fish and other animals found within its habitat.
Nesting occurs in spring when females lay eggs in holes dug high up on river banks.
The dozen or so soft-shelled eggs hatch about two to three months later.

The above was from the book Australian Reptiles and Frogs by Raymond Hoser and now available on a fantastic CD-Rom along with a vast amount of other information, papers and the like on reptiles, frogs and other wildlife.
