It has been used in the past when initiatives such as Government Online, for example, are established. In this case, vote 10 was used to transfer funds to government departments. You can use supplementary estimates or estimates processes, or you can use allocations from central votes, but the description of the central votes is actually on page 147 of the supplementary estimates. So get a sense there that vote 10 is to supplement other appropriations, if you have a government-wide initiative. And you normally report against that vote.
