The Australian emperor dragonfly, also known as the yellow emperor dragonfly, the Baron Dragonfly in New Zealand, scientific name Anax papuensis, is a species of dragonfly in the Aeshnidae family. It is black with yellow dots along its tail.
The Australian emperor is a very large dragonfly, up to 70 mm long. Its abdomen is marked boldly in black and yellow. The thorax is greenish-grey. The head is yellow with a T-shaped mark on the forehead (frons). The eyes are yellow-green. The leading edges of the wings are yellow. The insect habitually hunts fairly slowly, patrolling up and down like other hawkers, with short bursts at high speed.
Their wingspan is 11 centimetres (4.3 in). Males and females are similar. The Australian emperor is found throughout Australia. In the state of Victoria, it has a split distribution: below about 600 metres in altitude, and above about 1200 metres, apparently because it avoids forested areas. It is also found in New Zealand, New Guinea, the Cocos-Keeling Islands, Java, Sumba and New Caledonia.
The Australian emperor is widespread and common on larger bodies of water with tall vegetation on the banks. Like... Wikipedia →

Possible
About 20% of wildlife watchers report an Australian Emperor sighting in Hattah-Kulkyne National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 61 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Australian Emperor is recorded against all the insects logged in Hattah-Kulkyne National Park (9 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.
