Size Range
Southern populations are larger than northern ones, but also individuals from west-flowing rivers in New South Wales are larger than those found in the state’s east-flowing streams. Similarly, King Island specimens are smaller than those found in Tasmania and Victoria. Males are larger than females and can be over 60 cm long (tip of the bill to tip of the tail). Typically, males are 400-630 mm long, and females are 370-550 mm long. The weight is 800-3000 g for males and 600-1700 g for females.
