If you cant find anyone - why not try looking through some of the reputable Oz magazines on spirituality. I notice some people have been advertising for years - you might at least be able to ring them and see which one would suit your purposes.
Is there an accredited Hypnotherapy Association in VIC? they maybe able to give you some leads in the right direction.
Hope you search is fruitful!!
