i feel its drive train related as the sound happens at the exact time that the engine is about to start to rev upwards, i.e it would be the same time that you would expect a loose drive shaft to knock or something like that, but instead i get this kind of clutchy/gearboxy gnashing / crunch sound.
also with the engine pinging, id assume id hear it after i begin full load acceleration, but the sound only happens just on the initial applicaiton of the throttle. once continuing application of throttle no such noises are apparent
only reason why i am applying this kind of load in such a high gear is just to diagnose any potentially issues with the car and help it break in at a different load / rpm combination
thanks again for the responses so far though!

your pretty much getting the same issue that i'm getting and now after i got it back from the service centre and foreman giving it a road test, its a lot more noticeable and worse.
what happens if you back off the throttle and then accelerate again? do you hear it? and if so, does this noise comes back intermittently ?
Your best bet is to call your service centre and let them diagnose the issue and raise it up with toyota aust. I do think its pinging but i'm no Toyota mechanic.
