Oh, the issues with respect to cost.
I think they're very difficult to try to pin down exactly. And one should not actually be in a position to ask people why they're asking for that information and how they intend to use it, because if there's one cost for an individual and one cost for an institution, all the journalists would be making their requests in their own names, rather than in the names of their institutions.
There may be ways of reducing the cost to the government. For example, information brokers--it's probably incredibly inefficient for them to be asking for the same sort of information over and over again to get it updated monthly. Government departments should be entering into licence agreements and providing that information on a fee-for-service basis, then recovering their costs.
There may be ways of getting a lot of disclosure of information completely outside of the Access to Information Act.
