Possible
About 20% of wildlife watchers report a Jacky Lashtail sighting in Great Otway National Park on a given day, based on 61 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 19 reptiles we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
January, March and October
In those months about 30% of wildlife watchers report a Jacky Lashtail in Great Otway National Park on a given day, against under 5% in May to August, the lowest months.
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.
6th of 6
Of the 6 parks where we can rate Jacky Lashtail sightings, Great Otway National Park ranks 6th at about 20%. The best odds are in Grampians National Park (Australia, about 60%), Royal National Park (Australia, about 60%) and Booderee National Park (Australia, about 50%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Jacky Lashtail is recorded against all the reptiles logged in Great Otway National Park (61 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.
