Wow, that sucks Eric. I was happy enough that when I got inside the building after an hour and a half standing in line I only had to wait another 35 minutes to finally get called up to the counter to spend 10 minutes waiting for the Vicroads lady to process the paperwork, print me off the permit, fetch me a number plate and give me a logbook that I need to fill out every time I go for a ride. And take my money, of course.
My oldest boy left his 2002 Ford Explorer in my back yard, unregistered and unloved 8 years ago, when he moved interstate for work. He moved back just before Christmas last year, and when the lockdown happened, decided that as he was "working from home", he'd spend all his spare time fixing the car up and get it re-registered.
He did a really good job, I gave him a few pointers and let him use my tools, but he did all the work, so he replaced the dead fuel pump, new brake rotors and pads, flushed the brake lines using Spotty's "Suck-O-Matic" $27 dollar chinese brake bleeder, replaced the headlights, blinkers, front bumper, side steps, wheels and tyres etc. He took it to a local mechanic with a good rep to get it inspected for a Roadworthy certificate, and got ripped off to the tune of $3K for a basic service and lots of quoted work that was never done, most mechanics are just crooks, period.
Anyway, finally with paperwork in hand he made an appointment to have it re-registered, and even though he was the last previous owner and had the old registration documentation on him, they couldn't find his car in their computer system, and like you, they screwed him around for 5 hours before they finally, grudgingly gave him the new number plates.
As much as I'm happy that I've got my red plate and can now ride my K0 legally, Vicroads is a disgusting example of "Big Government Bureaucracy". I'm happy to have government bodies employing public servants where necessary (hospitals and nursing homes in particular) but as a government contractor, I could happily contract out the whole Vicroads department, convert as many "face to face" systems as practical to mail in or (better still) online transactions, which would reduce the amount of employees needed, and save the customers a huge amount of time and red tape. It makes sense, so of course, it'll never happen.........
