Animal lovers can use readily available technology in their struggles to protect roos against unwarranted cullings.
Remote controlled Hexacopters (http://hexacopters.com/) with videocamera are available off the shelf for about one grand.
With a reach up to a few kms they can survey most of Canberra’s nature reserves from their borders.
Video footage of roo killings may sway Canberrans against destruction of peaceful roo societies, our national symbol, and Youtube clips of joey decapitations may send ACT Tourism screaming to government.
Heavylift Hexacopter versions, or perhaps Dodecacopters, may be used to pipe loud distress sounds to unsuspecting kangaroo crowds that are in for the kill.
If that would fail, the copters may be used for smart bombing.
Dousing of their killer utes with butyric acid of Japanese whaler fame or persistent red paint, may deter even the hardiest of roo mercenaries.
