best place to buy after market parts? is it the end in oz?

in Australia, the last two services for me in Melbourne have been difficult.  does anyone have recommendations?  
I'd love to find a good solution so its easier to get it serviced in the future.
we need to replace all four bushes currently.  are these cars just going to disappear at this point?

try ultra tune i have had mine serviced there for the last 5 years and no problems

i've bought some aftermarket parts from a store called auto parts mate. theres one here in adelaide (thebarton i think?) and they have a feebay store.

not sure on bushings and the like, but ive bought new indicators tail lights grill and headlight surrounds, mirrors. basically external parts for an absolute steal
you could give them a try.
