Wow! Finally! Someone who has seen one in person! Please excuse me while I bombard you with questions. I have been searching for someone with first hand knowledge of these bars for over a month.
What's the word on these then? Are they able to minimize damage to the vehicle in a collision? Do they offer adequate protection from large warm blooded creatures crossing the highway at night? (We have deer, you have kangaroos.)
Not that you're likely to care in a mine, but how bad do they look when scuffed up? Do the realy spring back into shape after a bump?
Thank you in advance for any answers you can spare the time for!

Originally bullbars and roobars were there to stop the animal from coming over the bonnet and through the windscreen and were sloped forward to achieve this.
They were also positioned up to 12 inches from the front of the vehicle so if they did bend it lessened the chance of damaging the vehicle body,particuarly the radiator.
To make them more pedestrian friendly the laws were changed in australia making it illegal for bullbar manufacturers to make bullbars that sloped forward.
They also had to be closer to vehicle.
Not as good for protecting the driver and vehicle as well as the old ones, but better than nothing.
The new plastic bullbars actually slope back to to gain areodynamic efficiency and lose all the abilty to stop an animal from coming over the bonnet and through the windscreen.
They will only protect the car from minor scrapes in the parking lot and maybe small animals at low speeds as the plastic is only a few centimetres from the body.
Whilst its true what Wayne says in relation to the plastic bullbar absorbing some shock ,the average driver will hardly be driving into walls on a minesite.
The ability for the plastic bullbar to save you from a collision with an elk,cow,horse or roo is non existant.(and it was never guaranteed with the old style either)
The claims for the plastic BB being more pedestrian friendly is also a liitle skewed.
The tests are done on a dummy representing a 10 yo boy at low speed showing less head injury.This testing is selective and the use of a child is designed to invoke emotion IMO
Hitting a taller person does the same as no bullbar,it sweeps the legs away throwing them onto the bonnet
The plastic scratches like any other hard plastic but so does that shiny alloy.
I took a heap of photos of plastic bullbars at a 4wd show last year but I have deleted them.
So far they are only being fitted to cars,mainly taxi cabs in large numbers where I am.
They maybe more suitable for the smaller softer light duty 4wd as they dont have a chassis or strong floor like the older 4wd.
The plastic jobs dont really deserve the name "bullbar or roo bar" .
Perhaps a "bump or scrape bar" or maybe the "politically correct bar"
