The Backyard Bandicoot

Have you ever noticed small conical holes and diggings on your property or Bushcare sites? These are likely the tell-tale signs of bandicoot diggings and activity.

You may have been lucky enough to encounter one of these small nocturnal mammals digging around in the leaf litter and soil, or walking through the undergrowth at night.

Bandicoots are typically solitary mammals that have sensitive noses which they use to opportunistically seek out insects, insect larvae, lizards, mice, snails, fungi, grass and fruits.

Type's of Bandicoot

Although there are seven species of bandicoots known to inhabit Australia, there are only two species which you might encounter in SEQ and the Sunshine Coast. 

The two types of bandicoots on the Sunshine Coast include:

(1) The Northern Brown Bandicoot (Isoodon macrourus), which translates broadly as long-tailed equal-tooth.

(2) The Long-nosed Bandicoot (Perameles nasuta), which translates to the notably nosed pouched-badger.

Although both species share some physical similarities and can share the same habitat, there are some distinct physical features that will help you tell them apart. Identifiable if you see them in person or on a fauna camera* on your property.

Northern Brown Bandicoot

Typically have a shorter nose, short round ears, longer tails, dark and coarse fur and can be a heavier build (average adult 2kg).

The shorter nose and ears are noticeable below in the photos of the Northern Brown Bandicoot.

Long-nosed Bandicoot

Long-nosed Bandicoots are known for their long nose / snout, longer pointed ears, shorter tail, often paler fur (although not always) and slighter build (average adult 1.5kg).

The long snout and large pointed ears are most noticeable in the below photos of the Long-nosed Bandicoot.

Bandicoots can sometimes get a bad reputation for digging up gardens and the lawn on the edges of bushland areas, but these diggings are known to be a vital ecosystem service.

A single Bandicoot can dig up to 4 tonnes of soil per year! This equates to a lot of mixing of soils and sediments –also known as bioturbation of soils** – throughout our Bushland Reserves and properties throughout the Sunshine Coast.

The process of bioturbation is known to increase nutrient availability, microbial and fungal activity. This activity can then increase seed germination in the soil heaps / piles that have been turned by the bandicoots.

Next time you see some bandicoot diggings or identify one on a fauna camera, you will have a better understanding of which one of the species you may be looking at, and the significance of those little diggings.

**Bioturbation is the mixing of (plant) residues into soils and sediments by biotic activity.
