Both rats and mice are considered serious pests due to their eating and contaminating food, damaging property, and spreading diseases.

A notifiable disease is any contagious disease that is required by law to be reported to the national health department. In Australia, The National Notifiable Diseases Surveillance System (NNDSS) was established in 1990. All diseases classified on this database must be notified to the Australian Department of Health.
