Personal experience ,
Only hit roos on one trip . I hit one at the start .' Good bullbar ' ,so checked it's pouch, & that it was deceased.
Between Gundawindi & Mitchell Queensland. No problems , Birdsville, down that Birdsville track , to Lyndhurst, And back up the
Strzelecki track, to Cameron's Corner ,back to Burke were that evening , we had a mob of Kangaroos jump into the gleam of our headlights.
Pushed that ' roobar back into the bonnet and the two mudguards, knocked us off the road into a tree ' backwards ' damaging the rear door.
BUT THAT ' ROOBAR 'did it's work , and we drove on " unhappily " . Lucky was only doing 80 in a 120 kph area of Mitchell highway .
