The rakali (Hydromys chrysogaster) is one of Australia’s native water rats, active in both freshwater and saltwater habitats (wetlands, streams, farm dams, lakes, estuaries, beaches). They have been seen by neighbours in my area, but unfortunately not by me.
So I was thrilled to see a photo of one taken by neighbour Liam Corbett, who was visiting Ballarat (Victoria) at the time. The rakali had come out to sniff his sneaker.
They are the closest thing to otters that we have and can get fairly large:
Rakali have a body 231–370 millimetres (9.1–14.6 in) in length, weigh, 340–1,275 grams (0.750–2.811 lb) and have a thick tail measuring around 242–345 millimetres (9.5–13.6 in).Source: https://en.wikipedia.org/wiki/Rakali
They eat fish, crustaceans, shellfish, small birds, eggs, mammals, frogs and reptiles. Their webbed feet aid in swimming.
They also can eat cane toads without dying – flipping the toads over on their backs to get at the stomach, thus avoiding the poison sacs on the shoulders.
Rakali are mostly solitary, and forage at dawn and dusk; when not foraging they rest in hollow logs and burrows.
They used to be hunted for their soft, waterproof fur, but have been protected such that they are common now, although shy and not often seen.
So it seems I’d better slip on some sneakers and quietly hang about some streams if I hope to see one in the wild.
