Chelodina longicollis is found throughout southeastern Australia, where it is found west of Adelaide (South Australia) eastwards throughout Victoria, the Northern Territory, and New South Wales, and northwards to the Fitzroy River of Queensland. Where Chelodina longicollis comes in contact with Chelodina canni the two species freely hybridise, exhibiting hybrid vigour in the Styx River Drainage of Queensland. C. longicollis has been introduced to Tasmania, likely via the pet trade.
Chelodina longicollis has also been introduced to the Perth and Albany metropolitan areas of southwestern Australia, where it is known to hybridise with the local oblong turtle (Chelodina oblonga). This is again likely due to long... Wikipedia →

With luck
About 10% of wildlife watchers report a Common Snake-necked Turtle sighting in Sydney on a given day, based on 205 verified sightings from GBIF citizen-science data. It is the 16th most-seen of the 39 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
October and November
In those months about 20% of wildlife watchers report a Common Snake-necked Turtle in Sydney on a given day, against under 5% in June and July, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Common Snake-necked Turtle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 3
Of the 3 cities where we can rate Common Snake-necked Turtle sightings, Sydney ranks 2nd at about 10%. The best odds are in Melbourne (Australia, about 20%).
GBIF citizen-science records
It is estimated from how often the Common Snake-necked Turtle is recorded against all the reptiles logged in Sydney (205 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
