With luck
About 10% of wildlife watchers report a Southern Brown Bandicoot sighting in Great Otway National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 30 mammals we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
March–May and July
In those months about 20% of wildlife watchers report a Southern Brown Bandicoot in Great Otway National Park on a given day, against under 5% in June, September and November–February, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Southern Brown Bandicoot sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Southern Brown Bandicoot sightings, Great Otway National Park ranks 2nd at about 10%. The best odds are in Maria Island National Park (Australia, about 80%).
GBIF citizen-science records
It is estimated from how often the Southern Brown Bandicoot is recorded against all the mammals logged in Great Otway National Park (17 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.
