Hi there. I live in Sydney recently. I have international licence. But unfortunately I got 16 demerit points. What will happen if police caught me driving? Does it affect in PR? Will these points decrease yearly or in three years?
When (not if, but when) the police catch you still driving,
you'll quite likely be arrested, could well be charged (rather then merely infringed),
and, depending on your court outcome, yes, the Good Character condition of your current visa will be in play.
