The Calvert river and its tributaries race through the sandstone uplands of Pungalina to the broad floodplains below. In the wet season the waterways collect the monsoonal rain from the broad savannas before channelling it to the rich fishing grounds of the Gulf of Carpentaria. Fish and Freshwater Crocodiles use the ephemeral connectivity to travel to upstream pools that will become isolated when the rain stops. The waterways are lined by rock escarpments that frame tall paperbark and river red gum forests. During the dry season these highways of nectar-laden blossoms collect the flashing, screeching traffic of lorikeets by day and fruit bats by night. In the shady understorey of freshwater mangroves and pandanus, Azure Kingfishers opt out of the raucous life of the canopy and keep one self-confident eye on the Freshwater Sawfish and Gulf Snapping Turtles in the water below.
