[3] Like other pebble-mound mice, it is known for building shallow burrows with mounds of pebbles surrounding the entrances.

This function is understood to be protective and collects dew.

In Queensland the observed mounds in coastal areas are smaller than in drier habitats, reflecting the need to collect more of the scarcer water.

[2] The mouse lines the tunnel walls with pebbles for insulation and protection.

It plugs smaller openings to the burrow system with a pebble, camouflaging the entrance, and unplugs it to exit in times of danger.
