The Bynoe's gecko is a slender, long-tailed species which may grow to a total length (including tail) of 11–12 cm (4.3–4.7 in). It is covered with small scales which appear to be rough, but are soft to touch. It has slim... Wikipedia →

Possible
About 30% of wildlife watchers report a Common Prickly Gecko sighting in Kakadu National Park on a given day, based on 36 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 54 reptiles we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
January, May, July and September
In those months about 40% of wildlife watchers report a Common Prickly Gecko in Kakadu National Park on a given day, against under 5% in February–April and November–December, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Common Prickly Gecko sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 5 parks where we can rate Common Prickly Gecko sightings, Kakadu National Park ranks 3rd at about 30%, level with the leaders once rounded. The best odds are in Litchfield National Park (Australia, about 30%) and Flinders Ranges National Park (Australia, about 30%).
Same family: Gekkonidae
The closest relatives of the Common Prickly Gecko that you can see in Kakadu National Park (family Gekkonidae, Typical Geckos) are Common House Gecko (about 30%), House Gecko (about 20%) and Arnhem Land Spotted Dtella (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Prickly Gecko is recorded against all the reptiles logged in Kakadu National Park (36 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.
