So let me get this straight.....
You went to Redfern Station, walked through the unlocked gate and then discovered that you had lost your ticket. You decided that you shouldn't get on the train. Then you went up to the Cityrail stormtroopers to tell them your story and they said they were going to fine you.
BAD LUCK.
This happens to people of all backgrounds
every day at Redfern and other stations around the network. There is a big goup of Transit Officers every single day at Redfern Station and their main purpose (as far as I can gather) is to just stand there and hand out fines to any unfortunates souls who have lost or "forgot" to buy a ticket. They don't discriminate, they don't listen to whatever story you have to tell, they just hand out fines. Once they have handed out the fine, it's then out of their hands and they don't have to deal with it anymore, so it's not like they have any compassion or give a shit.

That's just the way it is FOR EVERYONE.
As far as i can tell, you refused to give them your details or provide ID. Subsequently, they rang the police, as is the normal policy when people refuse to give details. They are also within their rights to detain you while police are called, and until police arrive.
BAD LUCK.
Then you got taken to the police station and refused to give them details. It seems to me like you could have saved yourself a whole lot of trouble if you were just honest and told them who you were. Instead, you spent 3 hours dodging questions (i assume) and making trouble. You have nobody to blame but yourself.
Now, I don't know you, i don't know what you do and I don't know what you look like, but if seems to me like you may indeed be a prostitute.
EVIDENCE:
* Many condoms
* Dressed like a prostitute
* You refused to confirm or deny if you were a prostitute "for fear of being targeted by law enforcement types". If you weren't, then I think you would want to deny it pretty strongly! What would you have to fear if you weren't a prostitute?
* Police seem to be aware of you
* Police put down your occupation as prostitute
This whole story seems to be your own fault, and you have nobody else to blame. You were un-cooperative from the very start and the Transit Officers/Police were only doing their job.
