I did the same to mine on the RHS 3 weeks in, as I was not used to the large overhangs on the front coming from an A1 - also copped another one on the LHS couple of weeks back thanks to an errant metal bar on the freeway.. Have noticed these bumpers appear to be really 'soft'.
I'm also in Brisbane, could get a discount for two at a time, let us know how you go
