house mice (Mus musculus) were brought into Australia, and they are considered an introduced, invasive species. They are not native to Australia and were introduced by European settlers, primarily arriving as stowaways on British ships, including the First Fleet, in 1788.
Key Facts About Mice in Australia:
Arrival History: While the First Fleet in 1788 is the most likely primary introduction point, mice may have also arrived on earlier Dutch ships.
Source Region: Genetic studies suggest that Australian house mice originate from Western Europe, specifically showing a strong link to the British Isles.
Distribution: Mice are now widespread across the continent, particularly in agricultural and urban areas.
Impact: They are a major agricultural pest, causing significant economic damage by destroying stored grain and chewing through infrastructure.
Mouse Plagues: Australia is one of the few places in the world where mice reach, on average every four years, plague proportions (up to 3,000 per hectare), often occurring in grain-growing regions.
Native vs. Introduced Mice
It is important to distinguish the introduced house mouse from native Australian mice (such as the hopping mouse) and native rodents. Native rodents have been in Australia for millions of years, whereas the house mouse has only been there since European colonization. The introduced house mouse is responsible for competing with and disrupting the habitats of these native species.
