This fact sheet on the impact of pet cats on Australian wildlife shows that pet cats allowed to roam and hunt are a major threat to local wildlife.

Domestic cats were introduced to Australia with the First Fleet in 1788. They are now one of the most damaging invasive species worldwide, and in Australia have been a major driver of mammal extinctions.

Probably introduced into Australia by early European settlers tropical fire ants are highly aggressive and attack any intruder who disturbs their nest.

Yellow crazy ants are a highly aggressive tramp ant from south-east Asia that made it into Australia through our ports. In a suitable climate, such as the Queensland Wet Tropics, they can form “super colonies” that cover vast areas and carry huge social, environmental and financial impacts.

Former Palmer United senator Jacquie Lambie is backing a push to allow Tasmanian tomato growers to use feral bumblebees as pollinators in glasshouses.

A fact sheet with information about red imported fire ants (Solenopsis invicta) and the serious threat posed to Australia's environment, agriculture and way of life.

Invasive animals, particularly foxes, cats, rabbits and rats, have caused most of Australia’s animal extinctions and imperil many more species. Hardhoofed feral herbivores like goats and deer damage wildlife habitats and threaten many rare plants. How to control feral animals effectively and humanely to protect native species and ecosystems is one of the greatest challenges […]

A 'white list' or 'permitted list' approach to the sale and movement of plants is the safest way to prevent the spread of potentially weedy plants.
