Likely
About 60% of wildlife watchers report a Jacky Lashtail sighting in Royal National Park on a given day, based on 264 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 37 reptiles we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
January–February and October–November
In those months about 70% of wildlife watchers report a Jacky Lashtail in Royal National Park on a given day, against about 10% in July, the lowest month.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Jacky Lashtail sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 6 parks where we can rate Jacky Lashtail sightings, Royal National Park ranks 2nd at about 60%, level with the leaders once rounded. The best odds are in Grampians National Park (Australia, about 60%). All parks ranked.
Same family: Agamidae
The closest relatives of the Jacky Lashtail that you can see in Royal National Park (family Agamidae, Dragons) are Australian Water Dragon (about 70%) and Mountain Dragon (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Jacky Lashtail is recorded against all the reptiles logged in Royal National Park (264 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.
