clearing a few things up for me

[fonfe]

Hiya guys,

Am moving to Victoria end of this month and there’s a few things I’m not quite sure on and was hoping people could explain/confirm for me as being from the UK I haven’t got a clue on some processes/laws:


Roadworthy test - is this done every year or just when a vehicle is to be sold on to another person?

Rego -what on earth is this?

If I’m buying a car in Australia, is it just a case of I fill out the owner documentation send it off and that’s it I can drive the car? Or is there more to it than that?

Insurance - been told by someone it’s not a legal requirement to have it to be allowed to drive on Australian roads?

Road laws- do they differ from state to state?

Importing of a "kit car" - whats the deal with this?
Just i know that to import a car into Australia it must be in 100% standard form....what if the car is a mixture of several cars built into one such as a kit car? Does this give it a different status as far as being allowed in is concerned?
We have a thing called Q registration plates in the UK, if a car has more than 50% non original parts on it then it doesn’t count as being the car it was when it left the factory so gets put into a kit car category the same as a buy it in parts build it yourself from the ground up kit car or kit car hot rod. You have something similar?

anti-lag/nitrous/external wastegates & screamer pipes - road legal?

Stretch tyres - road legal?

Exhausts- must they pass the rear axle or are side exits road legal?

Roll cages -road legal or not? -been told by someone it is not legal to have one fitted to a road going car.

Engine conversions/modifications - again been told by someone that ANY alteration to a vehicle must be inspected by an approved engineer and then alterations made to vehicle documents.... this true?
How tight are the police on this?
It’s a similar sort of thing in the UK but very few people actually bother to go through the process as unless you’re in big accident that you caused no one is any wiser/cares what’s been done to your car so long as the engine isn’t about to fall onto the floor.

Are there any small laws I should be aware of such as side windows cannot be plexiglass, if abs or airbags are fitted it as standard it cannot legally be removed, all doors must open from the outside etc.

Thanks in advance sorry for so many questions!
