C. expansa primarily preys upon frogs, crustaceans, aquatic insects, and small fish. Predators The introduced red fox (Vulpes vulpes) and ravens (Corvus spp.) are the major threats to the nests of the broad-shelled river turtle. Predation of nests by foxes along the Murray River is in excess of 93% which means there is little recruitment of young turtles into an ageing population. As turtles are long-lived animals and adults are still commonly seen in the wild, this can lead people to falsely believe that the population is still healthy. Other nest predators include monitor lizards, ibis and feral pigs. Predation of nests is the main challenge for C. expansa, however it is thought that the turtle becomes aware of predators, mostly from olfactory and visual signs. Hatchlings face a variety of predators while they travel overland to water; these can include birds and lizards in addition to feral foxes and feral cats. Many young turtles also die from dehydration if they fail to reach the water in time, and some are killed whilst trying to cross roads. Once they reach the water, they may be eaten by fish and other aquatic predators. In the fragmented Queensland populations, the main predator of hatchlings is the spotted barramundi. Threats The broad-shelled river turtle may be infected with adults of the parasitic flatworms D. pearsoni and D. megapharynx. These flukes appear to be host-specific and live in the intestines of C. expansa.
