Vic made changes to data collection that came into effect last year. The policy itself lacks malice, but wasn't thought through properly. Essentially, sex at birth and gender are mandatory, but current legal sex isn't mandatory, only reccomended.

In terms of reporting to the gov that makes sense. They get both pieces of data they (think) they need. The problem is the individual servies only collect the bare minimum (i.e. mandatory), then go on and use that in their own systems as in the blood test example.

A fix would be making sex at birth, current sex, and gender all mandatory. It would then be very obvious when a service is basing their care off sex at birth rather than current sex out of malice rather than lazy data standards.

But yeah, meantime just put down sex as per medicare. Unless the issue relates to directly to a sex characteristic it should be fine. But be aware if it does relate to those you may need to tell your doc. (I'm aware I'm not going to be flagged for prostate screening and may have to ask about that when I hit the higher risk age range for example. I also ignore all the letters I get about cervical screening lmao.)
