Parklands are places of social interaction as well as habitats for complex non-human ecologies. These two processes - interacting with natural environments and with social groups - are connected and need to be considered together. In this paper I explore how cultural diversity and historical change have shaped the ways in which different groups of people perceive and act towards landscapes and animals in parklands along the Georges River and the National Park which surrounds it from Voyager Point downstream to Alfords Point. The various groups considered are Anglo-Irish, Aboriginal and Vietnamese Australians, all of whom have experienced the natural environment in their everyday activities like fishing and making a living. In doing so, they have interacted with each other, often expressing social conflicts through interactions about wildlife and nature regulation. I argue that we cannot understand how groups will relate to their natural environments unless we try to understand these inter-group political, cultural and historical conflicts.
