What reason would there possible be for no family or friend of this woman to make a statement in the media?
I can think of two court cases that are currently going through Australian courts that could provide the very reason. Because there are currently two female people going through court or have been through court, one in NSW and one in QLD, who used male language to describe a male person in media.
If a female person cannot be very clear that their issue is that the male person being 'male' is the very issue, then it does deter clear statements being made. It also means that some people will jump to the conclusion anyway that the person is just a bigot because the male person is 'trans' and that they are transphobic.
Seems a very possible reason why a person in Australia, particularly in NSW, would not make an explicit claim about a male person being a male person?
It would then also be victim blaming any female person for not speaking out about a male person being a male person if they feel they cannot do so without significant negative repercussions.
