This program launched 6 months ago but better late than never. There is apparently a questionnaire and the items are mailed to you so it’s not anonymous, but the source (Family Planning) seems legit.
I don’t have to tell you what the impact of unplanned pregnancy is on your career/finances or even just short term medical bills and time off work. Grab em if they’re free, and also hand them out to your mates.
For people over 30 and/or not in NSW the local family planning centres are likely to have these free as well.
Here’s a great resource for Victoria too. In addition to free condoms the Melbourne Sexual Health clinic does vaccinations and free needles/syringes.

Edit: The pilot for public free pad/tampon vending machines has ended in Melbourne but it seems free period products have been legislated in ACT so remain an option https://www.vic.gov.au/free-pads-and-tampons-public-places
