Yeah, I guess that’s right. I notice it’s similar in the US - far more steel bumpers than full bull bars. But you have deer? It’s not just Roos that are the issue here (although they’re probably 90%), also cows, feral pigs (I managed to clear up 9 once in the space of about 5m with my HZJ79) and up north feral donkeys, horses and camels. Had a mate hit cow in an HDJ79 towing 4.5T of firewood, wrote the ARB bullbar off but ute was untouched.
Also they spread the impact a fair bit when hitting another vehicle, I guess the authorities don’t like this either - more damage to what you’re hitting and less to you
