With luck
About 10% of wildlife watchers report a Blotched Bluetongue sighting in Grampians National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 19th most-seen of the 25 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Blotched Bluetongue is recorded against all the reptiles logged in Grampians National Park (10 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.
