A small population of Koala (Phascolarctos cinereus) are known to reside in dwindling habitat within the Cape Paterson hamlet, and the sounds of a koala call were heard in late 2019 in the South East Sector of The Cape where there is some remnant Coastal Manna Gum.

Koala diet is almost exclusively eucalypt leaves (Coastal Manna). They are active for a few hours per night and sleep most of the day. They are mostly solitary, but in the months of October – December, keep an ear out for their very loud, grunting call which is done to seek out a mating partner. They are strong climbers but move between habitat areas on the ground, so they are very susceptible to predators at this time.
