"There shall be payable to Her Majesty, in every year, out of the Consolidated Revenue Fund the sum of five thousand pounds mentioned in Schedule C to this Act to be appropriated to the welfare of the aboriginal natives, and expended in providing them with food and clothing when they would otherwise be destitute, in promoting the education of aboriginal children (including half-castes), and in assisting generally to promote the preservation and well‑being of the aborigines. The said annual sum shall be issued to the Aborigines Protection Board by the treasurer on warrants under the hand of the Governor, and may be expended by the said Board at their discretion, under the sole control of the Governor, anything in the Aborigines Protection Act, 1886, to the contrary notwithstanding. Provided always, that if and when the gross revenue of the colony shall exceed five hundred thousand pounds in any financial year, an amount equal to one per centum on such gross revenue shall, for the purposes of this section, be substituted for the said sum of five thousand pounds in and for the financial year next ensuing.
