I think this issue has been raised before, and we did take a look back. I think the review you're referring to is the review conducted by the Department of Finance on proposed legislative change, so that would be within the purview of the Department of Finance.
To answer your question specifically, no, that wasn't the crackdown. If you look at the OAG report, at exhibit 7.2, when they say they're finding an additional $3.4 billion a year, that isn't in the small and medium enterprise space. That's with multinationals, GST, large, underground economy, etc., so to answer the question, the extra $3.4 billion they're finding per year is not in the space that you're concerned about.
