VIC Legislation on Corporate Sponsorship of Australian Police Force?

[Samuel Martin]

I was just wondering if anyone would know if there is any legislation regarding corporate sponsorship of Australian Police Forces?

Seeing as though each state and territory has their own police force, this would apply to all states individually rather than just Victoria (as chosen in the heading of this question).

What's the background to your question?
