Hello Redjam, it depends on which GP you go and see. Medicare will pay for part of, and in some cases, all of the cost of seeing a GP. For Medicare to cover all of the cost, you need to see a doctor who bulk bills. You can find out if a clinic is a bulk billing clinic by ringing around and asking, or doing some research online. There are links to directories of health professionals on this website. For the non bulk billing GPs, I believe you can expect to pay at least $30 to see one for a 15 minute consultation.
A GP can write you up something called a mental health care plan, which provides you access to a certain number of subsidised sessions with a psychologist (I can't remember exactly how many it is these days, someone else may know, I think it's six or ten per year). Again, Medicare will pay perhaps half of each session, meaning it should end up costing you in the region of $70. There are also bulk billing psychologists, but these are much harder to find than GPs.
The bb helpling will probably have more reliable information and may have some ideas of who you can see as well because you will be able to tell them where you live.
