Your question is especially relevant for me today as I attend the last of my voice feminization therapy sessions at the Eye and Ear Hospital in the city.
This is run by La Trobe Communications Clinic:
I participated in a VFE (stemple) study last year, and this year voice feminization.
My experience has been positive. The most important thing to understand is that this takes time ... many months and realistically a few years. To sound female is more than just about pitch, it is also about emphasis, and structure.
I have no hesitation in recommending the La Trobe Communications Clinic.
It is best to make an enquiry ASAP as the waiting list can be months.
* I was made aware of the VFE by "Hayley" via the ZBGC noticeboard last year.
