About the Javan Rusa
The Javan rusa or Sunda sambar (Rusa timorensis) is a large deer species native to Indonesia and Timor-Leste. Introduced populations exist in a wide variety of locations in the Southern Hemisphere. Rusa is the Malay word for "deer" in general as well as lending the name to its own genus.
The Javan rusa is dark blackish brown and has a gray forehead. Its back is almost black, the underparts and inner thighs are yellowish brown. The abdomen is lighter brown, and the tail tuft is dark blackish brown. The hair is coarse and longer on the chest than on the remaining body. Its ears are wide and a little shorter than the head. The antlers are medium long and rather wide, the upper branch points forward. Fawns are born without spots. Males are bigger than females; head-to-body length varies... Wikipedia →

Where does the Javan Rusa sighting chance come from?
GBIF citizen-science records
It is estimated from how often the Javan Rusa is recorded against all the mammals logged in Royal National Park (55 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.
