Join the biosecurity conversation in Australia!

The Gold Coast will be abuzz with all things biosecurity on 12-13 June 2019, when government, industry and other interested parties unite for the inaugural Australian Biosecurity Symposium.

On its own the yellow crazy ant may not seem so scary, but when they link up to form super colonies, as they have done near Cairns, they can strip the forest of wildlife. Photo: David Wilson

Yellow crazy ants

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. Yellow crazy ants do not bite, but spray…

Our community coordinator Yvette Williams is keen for more volunteers to get involved in the Townsville Yellow Crazy Ant Community Taskforce.

Townsville Yellow Crazy Ant Community Taskforce

Highly aggressive yellow crazy ants are listed as one of the top 100 worst invasive species in the world, and sadly, have made it into northern Australia through our ports. Capable of forming super colonies, they threaten our Wet Tropics World Heritage Area and carry huge social, environmental and financial impacts. That’s why we’ve joined…

In late 2016 the Invasive Species Council and Island Conservation, working with the local community, began a project on Norfolk Island to better control existing invasive pests and prevent the introduction of new potential pest species. The project had two objectives: Controlling rodents and ants The first was to help the Norfolk Island community protect…

Where has all our wildlife gone?

We’ve joined Townsville City Council in the battle against yellow crazy ants in Queensland’s far north. Our new community coordinator Yvette Williams talks about what’s at risk.

Feral animals

The cane toad (Bufo marinus) is continuing its invasion of northern Australia. In 2001 it reached Kakadu National Park, many years ahead of expectations. All of the toads in Australia are descended from 102 toads collected in Hawaii in 1935. The Hawaiian toads came originally from Puerto Rico, the Puerto Rican toads from Barbados, and the…
