G'day Ricki & all,
 
I searched the Wilderness Society Shop http://www.wilderness.org.au/shops/ and its product list http://www.wildshop.com.au/ssl/product_index.asp but could not locate any "scaring device"
 
I use a pair of $20 warning devices But they emit an audible whistle when the vehicle is going fast enough. They work by air being forced through a venturi, much like an umpires whistle. Kangaroos, feeding on the side of the road sometimes will look up & freeze.
 
But those off the road bound off in all directions, including across the road. 
 
The devices have as much effect on scaring animals away as blowing a car's horn to encourage cattle to move off the road ie zilch !
 
An earlier electronic version called the "Shoo-Roo" allegedly emit an out of range signal and were trailed for some time by interstate express coaches but apparently did not meet expectations.
 
If anyone gets tempted to buy a pair, check it out in the store by blowing into them. One $9 pair I tried, had no hole through them at all !
 
Could it be that Eagles, Kites and Corvids feeding on carrion on the road get their first warning of an arriving vehicle by road vibrations ?
 
Regards
Bob Forsyth, Mount Isa, NW Qld.
