In terms of regular sightings, various mammals are the next most commonly seen animal along the river.
Grey Kangaroos and Swamp Wallabies being the most common. I've listed a number of the species that I saw below.
Platypus and Echidnas Monotremata
An old branch of mammals that lay eggs rather than giving birth to live young!
Most of the Australian native mammals are included in this large infraclass with the exception
of a few notable examples like bats, rodents and marine animals. Since most of the Australian mammals are
nocturnal, many would be about while I was recouping from the days paddle in a deep sleep. Because of this
I only really saw the ones that like to stay up late early.
Modern Mammals Placentalia
Most of the animals from this group that you will likely see are going to be
introduced farm or feral animals. Australia does have some placental mammals such as
native bats and rodents along with around 50 marine species such as seals, whales,
dolphins and dugongs.
Dingo fits into a fuzzy area, it is definitely a recently introduced animal but it also has fulfilled a role that
larger extinct carnivorous marsupials once played for many thousands of years now and helps regulate other feral
populations like foxes.
