Gosh actus - you should get onto the Finance Minister and tip him off on the work of fiction that is the CASA Annual Report.
The most recent one has a line item called "Revenue from Government" in the amount of about $43 million. ($42.801 million to be precise.). That amount was appropriated out of the consolidated revenue fund as part of the usual annual budget and appropriations bills process.
That line item is separate from the Fuel Excise line item (in the amount of about $118 million ($117.871 to be precise), appropriated out of the consolidated revenue fund as a consequence of the
Aviation Fuels Revenues (Special Appropriation) Act 1988.
(You do realise that fuel excise is just a kind of tax that
must be paid into the consolidated revenue fund
first, before there is anything available to be appropriated and spent (unless you know someone with the surname Khemlani ... )?
There is another Commonwealth safety agency that is funded substantially by appropriations from the consolidated revenue fund. Section 48 of the AMSA Act says, with the crap removed:
(1) There are to be paid to the Authority amounts equal to: ...
(2) Amounts payable under subsection (1) are to be paid out of the Consolidated Revenue Fund, which is appropriated accordingly.
But you'll learn all this in your later years of undergraduate study.
