There have been changes proposed to supplementary estimates in the government response. There are two key ones that I'll highlight.
One is a better format of information, where members could see what each department had in previous estimates, what they actually spent, and what their current year authorities are. The other change I should highlight is that in future supplementary estimates, to help parliamentarians better see the link between the budget and something in the supplementary estimates, when the government commits for the first time that new spending will appear in supplementary estimates or in estimates, it would reference back to the appropriate budget. Members would actually see the first time there's a new program that it came from budget 2013, for instance, so that would help at least to improve the link.
