The Rakali or Australian Water Rat dwells in freshwater lakes and rivers throughout Australia and Tasmania and on offshore islands. They are also found on New Guinea.

The Australian Water Rat or Rakali live mainly near permanent fresh water. They live on land but depend on the water for food. Rakali are also present along the coastline, H. chrysogaster do not need completely fresh water.

The Rakali or Australian Water Rat breed in the spring and summer. Females have an estrous cycle of approximately eleven days. The gestation period is about 35 days.

Rakali females can enter estrus immediately after giving birth, so litters can be produced only 35 days apart. Usually, Rakali have litters of four to five young. During a good breeding season, females can have two or three litters.

At birth, the young Rakali are blind. Young are born helpless and are cared for by their mother in her nest burrow until they are weaned, at about 35 days old.

They are usually lighter in color than the adults, but already have the characteristic white tipped tail and partially webbed feet.

The Rakali young grow quickly and are usually independent after about 35 days. However, after this initial growth, maturity to adulthood takes longer.

Breeding does not occur until the young are at least one year old and full size is attained at about two years of age.

Preditors of the Rakali are Eagles, buzzards and kites prey on water rats, as well as snakes and small mammalian carnivores. Rakali or Australian Water rats mainly escape predation by escaping to burrows or into the water.

Rakali or Water rats are abundant and are an important prey base for many small to medium-sized predators. Their burrowing and foraging activities also help in the redistribution of nutrients in systems.
