With luck
About 10% of wildlife watchers report a Brown Bunyip sighting in Brisbane on a given day, based on 298 verified sightings from GBIF citizen-science data. It is the 47th most-seen of the 1083 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
December and January
In those months about 30% of wildlife watchers report a Brown Bunyip in Brisbane on a given day, against under 5% in April to October, the lowest months. Those are among Brisbane's wettest months, with about 140 mm of rain a month against 40 mm in July.

Across all the parks we cover, that three-hour window holds the most Brown Bunyip 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.

GBIF citizen-science records
It is estimated from how often the Brown Bunyip is recorded against all the insects logged in Brisbane (298 verified sightings), 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.
