The perentie (Varanus giganteus) is a species of monitor lizard. It is one of the largest living lizards, after the Komodo dragon, Asian water monitor, and the crocodile monitor. Found west of the Great Dividing Range in the arid areas of Australia, it is rarely seen because of its shyness and the remoteness of much of its range from human habitation. The species is considered to be a least-concern species according to the International Union for Conservation of Nature.
Its status in many Aboriginal cultures is evident in the totemic relationships, and part of the Ngiṉṯaka dreaming, as well as bush tucker. It was a favoured food item among desert Aboriginal tribes, and the fat was used for medicinal and ceremonial purposes.
British zoologist John Edward Gray described the perentie in 1845 as Hydrosaurus giganteus, calling it the "gigantic water lizard". George Albert Boulenger moved it to the genus Varanus. Within the monitor genus Varanus, it belongs to the subgenus Varanus.
Perenties are found in the arid desert areas of Western Australia, South Australia, the Northern Territory, and Queensland. Their habitats consist of rocky outcroppings... Wikipedia →

Possible
About 20% of wildlife watchers report a Perentie sighting in Ningaloo Marine Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 29 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.
February and March
In those months about 40% of wildlife watchers report a Perentie in Ningaloo Marine Park on a given day, against under 5% in October and November, the lowest months. Those are among Ningaloo Marine Park's wettest months, with about 35 mm of rain a month against almost none in October.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Perentie sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
2nd of 3
Of the 3 parks where we can rate Perentie sightings, Ningaloo Marine Park ranks 2nd at about 20%. The best odds are in Uluru-Kata Tjuta National Park (Australia, about 30%).
Same genus: Varanus
The closest relatives of the Perentie that you can see in Ningaloo Marine Park (genus Varanus, Monitor Lizards) are Gould's Goanna (about 20%) and Ridgetail Monitor (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Perentie is recorded against all the reptiles logged in Ningaloo Marine Park (17 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.
