I went last Tuesday, got there at 7 30 and was number 4, out by 11 am, the guys on security give you a number card on arrival, they said if Ihad gone on Monday I would of been No 10 by 7.30.
I waited over 5 weeks using the post service, gave up and drove down there.
The public counter is open from 8.30 at the moment. Good luck.
