Red-necked wallabies are mainly solitary but will gather together when there is an abundance of resources such as food, water or shelter.
When they do gather in groups, they have a social hierarchy similar to other wallaby species.
A recent study has demonstrated that wallabies, as other social or gregarious mammals, are able to manage conflict via reconciliation, involving the post-conflict reunion, after a fight, of former opponents, which engage in affinitive contacts.
Red-necked wallabies are mainly nocturnal.
They spend most of the daytime resting.

A female's estrus lasts 33 days.
During courting, the female first licks the male's neck.
The male will then rub his cheek against the female's.
 Then the male and female will fight briefly, standing upright like two males.
After that they finally mate.
A couple will stay together for one day before separating.
A female bears one offspring at a time; young stay in the pouch for about 280 days, after which females and their offspring stay together for only a month.
However, females may stay in the home range of their mothers for life while males leave at the age of two.
Also, red-necked wallabies engage in alloparental care, in which one individual may adopt the child of another.
This is a common behavior seen in many other animal species like wolves, elephants, and fathead minnows.
