Hi Emma,
I just had a look at the freedom of information laws in Aust. and also the privacy laws for managing personal data.
Firstly it seems that Aussie has a bit of an issue releasing FOI data.

Another way of tackling this, if your recent request to Victorian Police is fruitless, is using your Privacy Act, 1988. From what I can tell an individual can request data that is held about them personally from both private sector and government agencies. So in the first instance fire off a request under the Privacy Act requesting any data held on you as a person. Depending on how that goes you have 2x options.
1. If declined: get your Privacy Commissioner office to look over your case and give you some guidance, support.
2. If data is released on you, then you can look it over to make more targeted FOI requests. Given that it seems your FOI system is over-loaded and not functioning well this may be a more fruitful approach. You do have the right to your personal information in Australia.
Data on your privacy laws and steps to take to make requests.
