The threat is at its worst in the north of the country, where large areas are fast becoming marsupial-free zones.
In Kakadu National Park in the Northern Territory, there are now 20 species of small marsupial that seem to have disappeared altogether.
The threat is being blamed on feral cats which hunt the animals but have only started doing so in the last few decades, begging the question, what has changed?
New analysis blames graziers’ fires and other environmental changes that have created a perfect hunting ground for the wild cats, and scared away other animals that may have been on the menu.
Either way, a team of wildlife experts are on the case to reinstate the little rippers before they join the Giant Wombat in the history books.
