I don't have what a specific cost of a privacy impact assessment would be, but it strikes me as being good governance that, as we're introducing legislation or changes in policy, this would be an outreach that could potentially save government money in avoiding errors in the future. I don't see that conducting a signal check, an assessment with the engagement of the Privacy Commissioner, would add to it significantly.
I would want to have a discussion with him and with his office about what an increase in the level of activity could mean for them. It strikes me that the level of activity may not increase, but that it would front-end-load his office's work. It may not increase the actual burden in their shop, but it would increase the efficacy of their intervention, because it would be earlier on.
