The Commonwealth, by way of Parliament, determines which are indictable offences.
Sexual offences are included in the long list.

If this is to change, it requires the cooperation of the Senate to pass any proposed changes.p to that list. Best of luck on that one.

Defendants charged with an indictable offence have a right to a trial by Judge or Jury. (Roughly speaking).

The fear of changes to this norm by the author, are based in her argument of a simple case.
But if a rape of a women occurred by multiple offenders, then the field is complicated by numbers, and it’s agreeable, a Judge alone may be the best option for an all-round just trial, which may, in some cases, find some of the accused liable to lesser charges.

I can see, it may well be expeditious for a judge alone trial to conclude on all issues with some simultaneousness.

Also, I can see that any proposed changes may have the opposite effect of leniency being a highlight and cause for public concern in itself.

Problem is, it is difficult to deny that Judges are political creatures; and the issue of a female Judge presiding on a rape trial, is too often judged as prejudicial.

A jury trial is by far a safer option in my view.
