I think there is a more general point about the Australian (and our judicial) system that it is structurally tipped in favour of the defendant. Firstly, of course, that the burden of proof is 'beyond reasonable doubt in such cases. But also that the defendant has several attempts at acquittal - not just the original trial, but then appeal and potentially supreme court (or equivalent). The defendant only needs to win in one of those three stages to be permanently acquitted - the prosecution needs to win in all three for the conviction to be sustained.
Now I'm not saying that is necessarily wrong, but it does bias the system in favour of the defendant, but I do have some concerns in types of offence where the key is consent, where there is perhaps very little independent forensic evidence - potential such as rape, sexual abuse etc. I think it also makes it more difficult for victims to come forward if they understand that they have to be successful at three separate stages to secure justice.
