I totally agree with you there is some thing very wrong when a camry needs suspension bushes at 150klms they must have been on very very rough road for most of its life Dosent make any sense

i reckon the damage to bushes was a combination of two factors. Firstly, that the car is sitting on 17inch 225mm wide wheels. While these are stock rims (GTP) they will wear the suspension out a lot quicker than stocko 15inch 205mm wheels. Secondly, i now know the springs have been replaced with standard height 'king springs'. These are harder than the touring model stock springs and would place additional stress on suspension components.
since starting this post and thanks to several very helpful replies, i have replaced the major parts of the suspension which were failing including, front struts (kyb inserts), wheel bearings, lower control arm bushes (front and rear), strut bearing plates. She handles a hell of a lot better. not all those bushes were worn out but whilst the car was apart and i could replace with polyurethane items i thought i may as well. Do it once and do it properly is a motto i've learnt the hard way with previous cars.
all up, to purchase and have fitted those parts, i'm out of pocket $1136. If anyone is interested in individual prices etc or help on where to buy (some parts were quite difficult to get hold of), please message me.
For the record, the engine mounts are showing some signs of wear, but still keeping the engine in place with no clunks etc. For the time being i've decided not to change them.
