In short:

A national study into bandicoots has uncovered new knowledge, which researchers say could have some big implications for the marsupials in South Australia.

While there was previously believed to be only one bandicoot species in the state, research has revealed there were once three.

**What's next? **

The southern brown bandicoot is already classified as an endangered species, which could mean a "conservation reassessment" for a new subspecies.
