Not sure of the difference between front/rear gen 1 vs gen 2, but for front bumper, bonnet & wheel guards, I was quoted at $500ish for my gen 1, figure you'll be up for something similar
You might get away with a partial bumper re-spray - cost me $300 in Melb - he came out to site, and did it in my car port.
I've had PDR done on my car too, cost me a slab (mates rates)
The challenge is the blending of silver paints - it's very hard.
Have a search on google and get in contact with a bumper repair person local to you, sure there would be someone in Perth who would do onsite bumper repairs.
