(a) any contributions or other payments payable by him or her under this Act;
(b) any benefit payable to or in respect of him or her under this Act; and
(c) any payment which may become payable from the Consolidated Revenue Fund to the Superannuation Fund, or from the Superannuation Fund to the Commonwealth, in respect of him or her under this Act;
be read as if any reference to an amount of salary, contribution, benefit, or payment, or to any other amount, were a reference to the amount in that foreign currency that corresponds with that amount.
(3) For the purposes of subsection (2):
(a) the amount in sterling that corresponds with an amount referred to in this Act shall be calculated on the basis that 1 pound sterling is the equivalent of $2; and
