First NSW and now Tassie!
I have found 2 nests in the last year on my property in South East QLD. Never been stung, but they are very aggressive.
For those who don’t know, you can report Fire Ant sightings here for Queensland. They were good with getting in contact with me, and usually took around 7 days to come and treat my property.
They have acclimatised to Australia as well. Here’s a video showing them making rafts during recent floods.
