Queensland will set up a horseshoe-shaped zone that dips into New South Wales for the first time to prevent the further spread of fire ants, which are now within 5.5km of the border.
The state government’s four-year plan, announced Tuesday, includes forming a 10km band around infestation zones, stretching from Moreton Bay in the south-east of Queensland, west to the Lockyer Valley, east into the Gold Coast and south to the Tweed Shire.
