Ash, say since im on my nsw p's i can legally drive my car no matter where i go, because my licence allows that. just because im in vic doesnt mean my licence changes to a vic one. same goes with rego, if ur car is reg in nsw/vic then it has to obey to those laws as u answer to that state
but defects have to be cleared by that state that they are given in
oh and make sure if ur done in another state that ur state knows its cleared.
remember how i got defected at heathcote back in 03 for bald tyres? well i got it cleared at vic roads and 3 months later RTA NSW sends me a letter asking y i havent had the defect cleared yet. damn gov depts
