This undirected network contains interactions between free-ranging eastern grey kangaroos (Macropus giganteus) in the Nadgee Nature Reserve in New South Wales, Australia. A node represents a kangaroo and an edge between two kangaroos shows that there was an interaction between them. The edge weights denote the number of interactions.
