There is no reliable test to confirm whether one is transsexual or not, and any therapist selling one is probably best avoided. (Not that I know of
any therapist who makes any such claims). We are still largely self-diagnosed at this point, though maybe at some point that will change, given some of the recent research on physical brain differences associated with gender identity.
Also, therapy approaches are pretty haphazard here in the States, at least, and I imagine the same is reflected elsewhere. Therapists tend to choose an approach that fits them, and it hardly seems very systematic at this point. I don't know how easy or not it is to "shop" for a therapist in Australia, compared to the States, but I'd definitely suggest digging into the details and asking some blunt questions about any therapist's approach and discipline before even tentatively committing to work with them over any length of time.
Most will not tend to offer directive advice, but will engage in talk therapy over time to eventually arrive as some sense of which issues to address first. Sometimes, trying to fix one thing directly can have unfortunate echoes somewhere else, so there is at least some logic to avoiding a fast "fix it" mentality, when the other issues you're facing could turn out to be complicated, and they may be waiting for you to reveal issues they sense you are not prepared yet to address or acknowledge directly. The "process" tends to feel like trying to hang Jell-O to the the wall, at least it did for me.
Despite some serious problems with my therapist, like ignoring my concerns that I might be bipolar, and encouraging (after over a year with him) a course of SSRIs that triggered the mania that confirmed I was in fact bipolar albeit with a very atypical presentation that at least my ex (an MD) considered odd enough that she felt he was not completely incompetent.... anyway, the benefits were:
- Developing Cognitive Behavioral Therapy skills for coping with depression;
- Problem solving during the period when I was not ready to commit to transition (partly due to the sense that it would mean the end of my marriage -- granted, my refusal to make a promise never to transition did lead to divorce anyway;
- EMDR work to deal with particular memories and incidents that may have been sources of the stresses behind my PTSD diagnosis;
- Ultimately, in a roundabout way, lengthy therapy did confirm to me much about the nature of my gender identity, details that can be useful for reflection, and that I hope, at least, will serve to help me maintain equilibrium when I finally do manage to put together all that is needed to proceed with transition.
In the end, though, much of what you accomplish in therapy is your own accomplishment, the therapist is often only there to serve as a sounding board, or a reality check, depending on what you need and how you see yourself working towards your goals.
If you are looking for something other than transition and HRT, best to ask about that as directly as you can. While therapists are not quite as manipulative and gate-keeperish as they were a decade or two ago, they are not likely to push you somewhere you don't want to go, but they may be tending more at this point to assume that most people presenting to them with gender identity issues are probably looking to begin HRT.
