Shooting from a vehicle is a cultural tradition down here. The majority of shooting (not hunting) would be spotlighting off the back of a ute. It is so common & such an important part of rural life that most properties will have at least one old or unregistered vehicle as a dedicated "shooting rig". There are some pretty creative alterations to these "franken-utes" & some folks do take it to the extreem to outdo their mates by adding every comfort or gizmo imaginable.
Our entire commercial kangaroo harvest (the largest wildlife harvest in the world) involves shooting from a vehicle without any animal welfare issues. Commercial shooters usually work by themselves so shoot out of the cab from the drivers seat. They normally have a rest attached to the drivers door, but the old land cruisers with the windscreen that folds forward is still a popular shooting platform for obvious reasons. Recreational shooters generally stand on the back tray & shoot off the cab roof, communication between the light, the shooter & the driver is usually through "tapping" on the roof of the cab. This code is simple, faster & safer than a voice.
Now that Toyota is killing off the 70 series Land Cruiser in Aust, we may however see a cultural shift. There should still be enough about though that will without doubt retire to be unregistered shooting rigs on farms all over the country that hopefully everyone should still have the opportunity to go spotlighting off one of these icons.
I don't know if you guys had the latest 4.5 L, v8 turbo diesel, 79 model Land Cruiser? Boy, are they good trucks & we'll miss them.
