Bandicoots are actually omnivores. Bush Heritage Australia, a non-profit organization working to protect Australian native species such as the Bandicoot says, “They’re opportunistic omnivores, eating both plants and animals, from insects, insect larvae, lizards, mice and snails, to fungi, grass seeds, berries and fruit.
They seem to ‘grunt’ happily when their muzzle chances upon food, and make a shrill squeak when disturbed.” It is also interesting to note that if a mother bandicoot cannot find enough food, she may have no choice but except to eat her baby. But for the most part, they hunt for their food in the dirt with their snouts.
