Why did the Broad faced potoroo become extinct?

Unlike most other Australian native animals, the Broad faced potoroo does not appear to have become extinct as a result of European settlement. Studies indicate the population of this small marsupial had declined before land-clearing became common, and before the red fox was introduced. Neither of these events helped its cause, of course.

Feral cats were believed to have come as a result of Macassan and Dutch ships visiting the Australian coast long before Britain colonised the continent, so most theories suggest that feral cats were the direct cause of the extinction of the Broad faced potoroo.
