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...

Possible
About 30% of wildlife watchers report an Olive Python sighting in Kakadu National Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 13th most-seen of the 54 reptiles we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
March
In that month about 50% of wildlife watchers report an Olive Python in Kakadu National Park on a given day, against under 5% in November and December, the lowest months. That is one of Kakadu National Park's wettest months, with about 170 mm of rain against almost none in August.
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.
2nd of 2
Of the 2 parks where we can rate Olive Python sightings, Kakadu National Park ranks 2nd at about 30%. The best odds are in Litchfield National Park (Australia, about 40%).
GBIF citizen-science records
It is estimated from how often the Olive Python is recorded against all the reptiles logged in Kakadu National Park (22 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.
