Nup, you absolutely can only have a number of sessions, and I understand why they do that. Because it's free they can't keep seeing people long term. I think there is only one psychiatrist in the area as well and usually there is a 2 month waiting list, sometimes longer to see him. I think what happens is once they know what meds work for you then you get repeats and once the repeats run out you can just go to your gp to get a refill. That's how it works in NZ anyway. You could probably see the psychiatrist again if after awhile your meds stopped working and you needed a reevalution. imo that doesn't seem unethical.
