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.
