The Northern Territory Health and Department of Health and Community Services (DHCS) and the Australian Quarantine Inspection Service (AQIS) have released details of the interception of a high-risk importation of exotic Asian tiger mosquitoes in cargo unloaded at the East Arm port facilities in Darwin in the Northern Territory. Eradication and follow up surveillance operations have started and it is expected the importation of these high risk Asian tiger mosquitoes will be eradicated. This has been a great example of the thoroughness of AQIS inspection and reaction procedures in both Western Australia and Darwin, and the continuing local cooperative programs between AQIS and DHCS.
