First was a drug charge, found guilty no conviction record.
2nd was assault, found guilty no conviction recorded.
3rd was affray, found not guilty.
As far as I am aware all those are still on the record but they don't get pulled up for standard job interviews etc. Only for high security positions (ala government/child care). They still very much exist on my arrest record as I was given a good behaviour bond that I didn't break so I didn't get a conviction.
I'm honestly not 100% sure how it works, been nearly 10 years since I went through all that. I *think* after 10 years with no law breaking they get removed from the record all together.
