Profile description
The Eastern Snake-necked Turtle is native to freshwater wetlands, farm dams and slow waterways of eastern and south-eastern Australia, with seasonal overland movement. Shell length commonly 20 to 25 cm, with a neck that can approach the shell length. Expected captive lifespan is frequently 30 to 50 years with long-term appropriate care. The Eastern Snake-necked Turtle is an aquatic, carnivorous and strong-swimming turtle that requires substantial water volume and may produce a defensive musky secretion. Its natural feeding biology is primarily carnivorous, taking aquatic invertebrates, fish and carrion. Captive diets require variety and correct whole-prey or formulated turtle nutrition.
Australian freshwater turtles are long-lived aquatic reptiles whose health depends on water volume and quality, complete drying and basking opportunities, ultraviolet-B exposure and a species-appropriate diet. A turtle surviving in a small unfiltered tank is not evidence of adequate welfare. Shell, skin, eye and respiratory disease often reflect chronic water, temperature or nutrition problems and may be advanced before obvious weakness occurs.
Small aquariums, poor filtration and lack of a completely dry basking platform cause chronic shell, skin, eye and respiratory disease.
Eastern Snake-necked Turtle (Chelodina longicollis) is a native reptile included on the Queensland Government's current keeper-licence species search; the listed Queensland requirement is Queensland Standard Licence. State and territory rules for the Eastern Snake-necked Turtle, including licence class, possession, breeding, movement and records, differ and can change. Obtain the Eastern Snake-necked Turtle only from a lawful captive-bred source; native reptiles must not be taken from the wild and exotic reptiles cannot be imported as pets. Keepers must confirm current licensing and movement requirements for the Eastern Snake-necked Turtle with the relevant state or territory authority before acquisition.
First-time reptile owner tips
Practical preparation for welcoming this reptile into your care.
Care requirements
Provide a large filtered aquatic system, easy access to a fully dry heated basking area with UVB, safe water depth, temperature monitoring and regular water testing. Maintain long-term plans for adult size and lifespan. The aquatic system needs powerful filtration, regular partial water changes, testing of temperature and nitrogenous waste, and enough room for normal swimming and turning. The basking platform must support the whole turtle, remain dry and provide heat and UVB. Feeding should minimise water fouling, and all equipment must prevent entrapment or burns. Turtles should be lifted with two hands supporting the shell and kept away from food-preparation areas because of Salmonella risk.
Feed the Eastern Snake-necked Turtle a varied species-appropriate aquatic diet and remove uneaten material before it degrades water quality. Portion food by age, activity and body condition rather than encouraging rapid growth. Feed for the species and life stage rather than relying on a generic reptile diet. Maintain clean, correctly filtered water for the Eastern Snake-necked Turtle and provide safe access to a completely dry basking area.
A reptile-experienced veterinarian should assess the Eastern Snake-necked Turtle after acquisition, with routine reviews at least annually thereafter. Quarantine a new Eastern Snake-necked Turtle in a separate room with dedicated equipment for a veterinarian-directed period before sharing air, water, furnishings or tools. The Eastern Snake-necked Turtle's biosecurity starts with everyday enclosure hygiene. Remove the Eastern Snake-necked Turtle's waste promptly, clean food and water containers, disinfect with a reptile-safe method and rinse thoroughly. Wash hands after handling the Eastern Snake-necked Turtle or its enclosure, supervise children and vulnerable people, and keep the reptile and its equipment away from food preparation.
Urgent veterinary signs in the Eastern Snake-necked Turtle include breathing difficulty, collapse, seizures, severe weakness, prolapse, major burns, inability to pass eggs, shell fracture or inability to submerge or reach the surface normally.
