Within the Bellinger drainage, a very restricted range,
M. georgesi was formerly widely distributed and locally abundant, with threats to its persistence including habitat modification and loss of native riparian vegetation, associated turbidification and sedimentation, predation by the introduced European fox, and competition with the recently introduced turtle
Emydura macquarii. In 2015, more than 90% of the adult population was wiped out by a virus, rendering the animal functionally extinct in the wild; a captive breeding program, with limited reintroduction, is working to re-establish a healthy population. Partially as a result of the extreme population decline caused by the virus (with a 97% mortality rate), the species was listed as
critically endangered by the New South Wales
Department of Planning and Environment in 2016. As of November 2022, while there is still no cure for the virus, the captive breeding program undertaken by
Taronga Zoo and
Symbio Wildlife Park has resulted in the release of 82 juvenile turtles back into the wild. ==Gallery==
