Two centuries of arrivals: Australia's major pests came first as cargo and livestock, lately as stowaways

"map out all major pests brought into australia and their origin countries and timeline"

This atlas consolidates 42 nationally significant introduced pests — mammals, birds, an amphibian, fish, insects and mites, and major weeds — from government, PestSmart, Weeds Australia, CSIRO and museum sources. 32 have a documented Australian arrival or detection year, spanning 1788 (First Fleet) to 2022 (varroa mite). 16 have a documented direct shipment origin; 16 more can be traced only to a native range, and 10 remain unresolved.

From origin to Australia — every documented route

Solid arcs: documented shipment source. Dashed arcs: native range only — direct shipment unresolved. Drag the timeline to replay arrivals; hover an arc or the list for detail.

Timeline of first arrival or detection, by category

One dot per species with a documented year, 1788–2022. Deliberate introductions dominate until the mid twentieth century; recent arrivals are accidental insects and mites.

1788 was year zero. Pigs, horses and prickly pear all landed with the First Fleet — the rabbit too, though the invasive population traces to the 1859 Barwon Park release of wild rabbits shipped from England. dcceew.gov.au

The nineteenth century was deliberate. Acclimatisation and hunting releases brought the fox (1855), deer, mynas and blackberry; 29 of the 42 species here were introduced on purpose. en.wikipedia.org

The cane toad marks the biocontrol era: shipped from Hawaii in August 1935 to eat cane beetles in north Queensland, it now numbers over 200 million. nma.gov.au

Modern arrivals are stowaways: red imported fire ant (Brisbane, 2001), fall armyworm (Queensland, 2020) and varroa mite (Port of Newcastle, June 2022) all arrived accidentally and are under national programs. dpi.nsw.gov.au

Method: consolidated from five research result sets (about 5,300 extracted records) covering PestSmart's national pest-animal mapping list, Commonwealth biosecurity pages, Weeds Australia profiles, CSIRO and museum histories, deduplicated to 42 species. "Major" is operational: nationally recognised vertebrate pests, invertebrates under national eradication/containment or established significance, and Weeds of National Significance or comparable. Years are the earliest documented Australian arrival or detection, not later spread; mainland and external territories (e.g. Christmas Island) can differ. Solid map arcs show documented shipment sources; dashed arcs show native range only, never presented as a proven shipping source; 10 species have no mappable origin and appear in the table only. Arcs are illustrative great circles, not voyage tracks. Incidental mentions, intercepted-only exotics and minor garden escapes were cut for scope.
