In some cases, we only have audio. I regret this, but our legal department informs us that we can't broadcast or publish some images without copyright clearance from the original copyright holder. An image that may be used for an education lecture in a single classroom or lecture hall falls within fair use provisions of the copyright act, while making it accessible online falls under those aspects of copyright law governing broadcasting and publishing.
Er -- no. Unless they have drastically amended the Aussie copyright statute and I missed it (which is not impossible, but somewhat unlikely) you don't have fair use provisions at all. As far as I know, the only countries with fair use are the United States, and now, since a couple of years ago, Isreal. Which is probably why your legal department is telling you what they told you. You probably *do* have statutory exceptions along the lines of "fair dealing" that function as you describe (certainly the United States does, in addition to fair use).
