How long do i have to pay rego (and greenslip) in NSW?

Question

rego + green slip due soon not enough money to pay for it

Answer 1

If you dont pay it by the day that it is due, you can no longer drive the car legally.

You then have 3 months in which to register the car with a pink slip.

If you havent done this after 3 months, you must surrender the numberplates and get a blue slip, and start again with a fresh rego.

Blue slips are a lot more thorough than a pink slip and take a lot more time, and are more expensive.
