No harm in asking at a community legal centre.
re: Job seeking. Use it to your advantage by saying you self reported, co-operated and still not been charged.
I did that. At every interview (13 interviews to be exact). Never got a response afterwards despite interviewing really well (you know your interview went well when it goes for over an hour).
So I decided to not mention it at interviews. Got job offers the same or next day. All those jobs offers (over 10 of them), immediately withdrew their offer of employment as soon as they saw the police check with the mention of “sexual assault”.
Go to show that being upfront and honest does not matter these days to employers.
