OP, i just got back on the road after doing the same 2 years ago cops word against mine, had no real proof, claimed 150+ (followed me at speed and said i still pulled away), dual lit empty highway.
long story short, car impounded for 30 days on the spot $821, sent to court (9 months later), 1 year loss of licence, $750 donation to royal childrens hospital, defensive driving course $150+, awareness seminar $300, 12 month good behavior bond (whilst suspended).
when i got my licence back i had to restart my p's, i then recieved another letter from vicroads informing me i had lost 8 points for the offence, 2 options 12 months 0 points good behavior bond, or 3 months loss or licence, went with option one as option two means i add another 6months to my p's
basically your f**ked, the silver lining is you can drink as much as you want without the hassle of driving
p.s to the people that care about the skyline image i sold skyline bought a diesel lux which on my lastest high speed test maxed 105km on a 3km stretch of road, so no more speeding for me and wrecking the skyline name
