I think a bushbar is Aussie, actually, for what we here in the lower regions call a pushbar or grille guard.
Kinda depends on what you do with the front bumper ... I have a Warn-ish bumper on one truck, with a guard thing welded to the front of the bumper. It would kill my approach angle, except it's on my 2WD tow rig. I use it as a handy step when doing engine compartment service

The studs on the front are the spare tire mount.
On my wheeling rig I just have a center guard, no grille extensions, which I use to mount a set of lights and hang my winch cable.
And on the CUCV, I have (duh!) the military issue grille guard. This is a GM thing and is actually pretty stout, i.e. you can stand on it and such. Would definitely protect from brush, small trees, etc, but would not stand up to elk, rocks, or small third world countries.
