Two unmanned aircraft systems (UAS) have been used as part of Project ResQu, which is led by the Australian Research Centre for Aerospace Automation (ARCAA), to detect weed spread in Far North Queensland. The autonomous helicopters have shown their ability to map weeds in remote terrain and provide a safer and more convenient alternative to using manned aircraft.

The UAS used sophisticated imaging technology to survey dense rainforest areas and successful detected weeds such as Miconia and other species, which is a positive step in the fight against biological invasions.
