The eastern rosella (Platycercus eximius) is a parrot native and endemic to south-eastern Australia. It was first introduced to New Zealand in cages, and individuals were subsequently intentionally released or accidentally escaped into the wild. In New Zealand, it is now established in the North Island (notably in the northern half of the island, Taranaki, Waikato and in the Hutt Valley) and in the hills around Dunedin in the South Island.
The eastern rosella belongs to the genus Platycercus and subgenus Violania along with other three species members: northern rosella (P. venustus), pale-headed rosella (P. adscitus) and western rosella (P. icterotis). An early analysis of rosella phylogeny stated that the eastern rosella and pale-headed rosella are most closely related to each other, compared to the other two rosella species. However, a more recent mitochondrial study found that the eastern rosella was the earlier offshoot of the lineage that split into the pale-headed and northern rosella, and those non-sister taxa were hence able to hybridize.
The three subspecies of eastern rosella are: P. e. eximius, mainly found in Victoria and southern New South Wales, Australia... Wikipedia →

With luck
About 10% of wildlife watchers report an Eastern Rosella sighting in Wilsons Promontory National Park on a given day, based on 51 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 62nd most-seen of the 138 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
March
In that month about 20% of wildlife watchers report an Eastern Rosella in Wilsons Promontory National Park on a given day, against under 5% in January–February and July, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Eastern Rosella sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 11
Of the 11 parks where we can rate Eastern Rosella sightings, Wilsons Promontory National Park ranks 3rd at about 10%. The best odds are in Egmont National Park (New Zealand, about 30%) and Grampians National Park (Australia, about 20%).
GBIF citizen-science records
It is estimated from how often the Eastern Rosella is recorded against all the birds logged in Wilsons Promontory National Park (51 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.
