why a carbon price with incentives, page-3

There are checks and balances, including the Auditor-General, to make sure it happens as designed.

I assume that the Future Fund is still outside of consolidated revenue. There are probably other examples that people can refer to.

Other countries have set up schemes not too different to this and they seem to be working okay. No reason for Australia to be less capable than, say, India in this regard.

It depends on the structure. The previous government misused the petrol excise as I recall (when John Anderson was deputy), but it was picked up and (partly) rectified and the roads budget was increased accordingly. And this was when the excise went straight into consolidated revenue so not as easy for the general public to see.

From what I read, the carbon price would always be kept quite separate and outside the normal budget, so it would be much more transparent and easy for even the general public to monitor.
