Hey Zac
I also live in Australia (QLD) and have never had any problems procuring herbs & substances of any kind. (feel free to email me for help here)
I am currently taking the 'Humaworm' herbs and they are working very well. I paid with credit card and they arrived promptly.
I would suggest that you post on that forum as he is very knowledgeable.
I personally wouldn't bother getting any allopathic parasite testing. I would just launch into a course of herbs for 30 days and continue reading here on Curezone, asking as you need to.
I also want to say that there is the bigger picture to focus on.. total body health.. of which parasite cleansing is a very important initial step (at least this has been my experience)
see you and best of luck!
