Another vote for Hume. My car's currently in there at the moment thanks to a ute rear ending me recently.
Price wise I think they're quite reasonable too. I figured that whilst my car was there, I get some cleanup done to some parts of the car that were already in bad nick when I bought it. The verbal quote was for some metal to be patched up (don't know if they bang it back into shape or fill the gaps), then strip back and respray the rear quarter panel over the wheel arch was gonna be $300, which I think is quite a reasonable price.
The other good thing for you is that they're on the southern side of Sydney, so it's a bit easier to get to than a lot of other places. Of course it begs the question of how you'll get from/to the place to drop/retrieve your car.
The real question is what is this new front bar of which you speak
