Hi Aubrey,
Welcome to Susan's family. It's good of you to drop in and say "Hi". Hope you like it here, and you stay for a while.
There is a mountain of information, resources and friendship waiting for you here, you just need to jump in start talking and ask any question you like. You're quite safe here and we are very accepting.
Just to let you know, I'm from north of Sydney and know a few girls from down your way. And as you've probably worked out, the 'Gong' is not all that Trans friendly. Most women I know from there travel to Sydney for therapy, electro, Endo, and voice therapy. Personally I don't of any medical professionals from there that are gender experienced.
Having said that, the Gender Centre will most probably be your best point of contact for the services you are looking for.
Anyhow, you first question first. Any doctor at your medical centre should be able to give you a referral to a therapist specialising in gender identity issues. You simply need to ask for one as you feel you have some gender identity issues. You do not need to be more specific than that, unless the doctor demonstrates knowledge and a willingness to help you.
Second. The Gender Centre have a good in-house counselor, or you can ask for a list of therapists specialising in gender issues.
Third. (a) laser (b) electrolysis (c) HRT
(a) HRT will change the dynamics of your body hair. To what extent is pretty much an individual result. There are topical applications your Endocronologist may recommend. When it comes to laser, shop around as the treatment, methodologies and prices vary widely. As does the effectiveness. I might suggest you look into this after you start HT and see what effects it has. And yes, if you are well endowed with hair, you'll need the tummy done as well. Of course don't forget your face. The top lip is a great exercise in pain management

Depending on your surgeon, if you go that far, scrotal electrolysis may also be required. Again if you're well endowed with hair, it may be mandatory. You don't really want hairs growing in your vulva. And electrolysis IS the only effective method that works.
(b) Electrolysis. Pretty much a ditto of the above. One practioner that some women use is in Balmain and charges something like $75-120 per hour.
(c) HT Again the Gender Centre should be able to give you a list of reputable Endocronologist. These people are few and far between. I know of only 2 in Sydney that really know their salt.
About transition timetables. They don't really exist. There is no hard and fast way to transition. You basically transition at your own comfort and speed. Once you get into it, you kind of sense when things need to be done.
If your considering singing lesson in order to learn how to sing; great. If you are thinking of it as feminine voice therapy; forget it. Singing lessons don't work that way. Stay with the Speech Therapist. The Gender Centre had a speech therapist in last month, outlining what a therapist would do with respects to voice training.
So roughly speaking, if you're still into timetables, here's a revised one. (a) do you research and find a good therapist, Endo and speech therapist. (b) check in with your local GP and ask for referrals to said specialists. (c) sit back, do the work and enjoy and embrace the journey.
Looking forward to hearing more of your story in time to come, but in the meantime, be safe, well and happy.
Lotsa huggs
Catherine
