Also called the Clarence River snake it is usually found close to water and is active during the day, feeding on frogs and mice. The scales are keeled (hence the name rough-scaled snake) and the body usually greenish brown with dark bands on the back.  Average length is about 0.71m, maximum 1.07m.  It is sometimes mistaken for the harmless keel back snake (Amphiesma mairii). This is considered to be an aggressive snake and may strike rapidly when provoked.
