Hi Lulu
=D> Congratulations on your decision. It is a very big step to take. My story is in LT TTC 'Donor Insemination' thread - too long to post here.
Can't help with any info about donors or procedures if you don't go through an IVF clinic.
But most IVF clinics will provide ART to single women. Trouble is, there's a donor shortage atm. I went through IVF Australia (North) and there were no problems. Medicare funding may be your only hurdle. Luckily (??) I had a history of infertility with my ex so could claim the rebate. I know IVFA have an 'East' clinic.
Good luck with your journey!!
