The olive python (Liasis olivaceus) is a species of snake in the family Pythonidae. The species is endemic to Australia. Two subspecies are recognized, including the nominate subspecies described here. With adults reaching over 4 m (13 ft) in total length (including the tail), L. olivaceus is Australia's third-largest snake species (surpassed only by the amethystine python and Oenpelli python). Its high number of dorsal scale rows (61–72 at midbody), makes the skin look smoother than that of other pythons. The number of ventral scales is 355–377. The colour pattern is a uniform chocolate brown to olive green, while the belly is usually cream-coloured. The adult weight is typically 10–20 kilograms (22–44 lb), and a large female can exceed 20 kilograms (44 lb) in captivity.
Unfortunately, this species is occasionally confused with the venomous king brown snake, Pseudechis australis, and may be mistakenly killed based on the misidentification. L. olivaceus is found in Western Australia, the Northern Territory, and Queensland. The type locality given is "North Australia; Port Essington" (Northern Territory, Australia). The olive python...

Likely
About 40% of wildlife watchers report an Olive Python sighting in Litchfield National Park on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 24 reptiles we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
January
In that month about 70% of wildlife watchers report an Olive Python in Litchfield National Park on a given day, against about 10% in November, the lowest month. That is one of Litchfield National Park's wettest months, with about 400 mm of rain against almost none in July.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Olive Python sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 2 parks where we can rate Olive Python sightings, Litchfield National Park has the highest daily chance: about 40%. Next come Kakadu National Park (Australia, about 30%).
Same family: Pythonidae
The closest relatives of the Olive Python that you can see in Litchfield National Park (family Pythonidae, Pythons) are Black-headed Python (about 40%) and Children's Python (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Olive Python is recorded against all the reptiles logged in Litchfield National Park (19 verified sightings from 2019 to 2026), 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.
