What happens when you get a train fine in NSW?

So I got my first train fine today because I forgot to buy my ticket – legitimately, I'm not just using the excuse. I was out all day and I catch the exact same train from and to the exact same spots every school day and I'm so used to using my school pass I forgot it was holidays. I don't know what to

So I got my first train fine today because I forgot to buy my ticket – legitimately, I'm not just using the excuse. I was out all day and I catch the exact same train from and to the exact same spots every school day and I'm so used to using my school pass I forgot it was holidays. I don't know what to expect. Some of my question might sound stupid, but I really don't know anything.
Does this go on some kind of record, like a criminal record?
Can I request to not pay the fine some how? What should that include?
Is it always $200- $550?
I can't tell my parents my father would just go crazy and my mum would never let me hear the end of it, so its pointless. I've already given myself plenty of reprimand over it.
Thanks for any help.
Could someone answer the questions I asked I'm well aware I have to pay for the fine regardless.

You didn't have a valid ticket – therefore you committed an offence. Whatever your reasons were, nothing is going to change that basic fact. Trying to use your school pass during the holidays is fraud.

You either pay the fine immediately, or go to court. If you are still a minor, your parents will be required to attend court with you – so if you try to go on your own they will find a police car at their door to take them to court. It will be a lot easier all round if you tell them what happened NOW.

This just means that you should pay it. You don't have to inform your parents about this matter.

You need to pay it. You made a mistake and need to pay to correct it. There are no excuses, you were not in school uniform so you should have twigged you needed to purchase a ticket.
